Methods / Constructors
Method / Constructor		Defined By
	new Gtk.TreeView (Object *properties) Create a new Gtk.TreeView Create a new Gtk.TreeView Parameters: Object properties*
	new Gtk.TreeView.with_model (TreeModel *model) : Gtk.TreeView Create a new Gtk.TreeView Create a new Gtk.TreeView Parameters: Gtk.TreeModel model* Required (not null) Returns: Gtk.TreeView
	activate () : Boolean For widgets that can be "activated" (buttons, menu items, etc. For widgets that can be "activated" (buttons, menu items, etc.) this function activates them. Activation is what happens when you press Enter on a widget during key navigation. If widget isn't activatable, the function returns FALSE. Returns: Boolean	Gtk.Widget
	add (Widget *widget) : none Adds widget* to container. Adds widget to container. Typically used for simple containers such as GtkWindow, GtkFrame, or GtkButton; for more complicated layout containers such as GtkBox or GtkTable, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_table_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can't place the same widget inside two different containers. Parameters: Gtk.Widget widget Required (not null) Returns: none	Gtk.Container
	add_accelerator (String *accel_signal, AccelGroup accel_group, Number accel_key, ModifierType accel_mods, AccelFlags accel_flags) : none Parameters: String accel_signal* Required (not null) Gtk.AccelGroup accel_group Required (not null) Number accel_key Required (not null) Gdk.ModifierType accel_mods Required (not null) Gtk.AccelFlags accel_flags Required (not null) Returns: none	Gtk.Widget
	add_child (Builder *builder, Object child, String type) : none Adds a child to buildable. Adds a child to buildable. type* is an optional string describing how the child should be added. Parameters: Gtk.Builder builder Required (not null) GObject.Object child Required (not null) String type kind of child or NULL Returns: none	Gtk.Buildable
	add_events (Number *events) : none Adds the events in the bitfield events* to the event mask for Adds the events in the bitfield events to the event mask for Parameters: Number events Required (not null) Returns: none	Gtk.Widget
	add_mnemonic_label (Widget *label) : none Adds a widget to the list of mnemonic labels for this widget. Adds a widget to the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). Note the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well, by using a connection to the GtkWidget::destroy signal or a weak notifier. Parameters: Gtk.Widget label* Required (not null) Returns: none	Gtk.Widget
	append_column (TreeViewColumn *column) : Number Appends column* to the list of columns. Appends column to the list of columns. If tree_view has "fixed_height" mode enabled, then column must have its "sizing" property set to be GTK_TREE_VIEW_COLUMN_FIXED. Parameters: Gtk.TreeViewColumn column Required (not null) Returns: Number	Gtk.TreeView
	can_activate_accel (Number *signal_id) : Boolean Determines whether an accelerator that activates the signal identified by signal_id* can currently be activated. Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This is done by emitting the GtkWidget::can-activate-accel signal on widget; if the signal isn't overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped. Parameters: Number signal_id Required (not null) Returns: Boolean	Gtk.Widget
	check_resize () : none Returns: none	Gtk.Container
	child_focus (DirectionType *direction) : Boolean This function is used by custom widget implementations; if you're writing an app, you'd use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. This function is used by custom widget implementations; if you're writing an app, you'd use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. So you may want to investigate those functions instead. gtk_widget_child_focus() is called by containers as the user moves around the window using keyboard shortcuts. direction* indicates what kind of motion is taking place (up, down, left, right, tab forward, tab backward). gtk_widget_child_focus() emits the GtkWidget::focus signal; widgets override the default handler for this signal in order to implement appropriate focus behavior. The default ::focus handler for a widget should return TRUE if moving in direction left the focus on a focusable location inside that widget, and FALSE if moving in direction moved the focus outside the widget. If returning TRUE, widgets normally call gtk_widget_grab_focus() to place the focus accordingly; if returning FALSE, they don't modify the current focus location. This function replaces gtk_container_focus() from GTK+ 1.2. It was necessary to check that the child was visible, sensitive, and focusable before calling gtk_container_focus(). gtk_widget_child_focus() returns FALSE if the widget is not currently in a focusable state, so there's no need for those checks. Parameters: Gtk.DirectionType direction Required (not null) Returns: Boolean	Gtk.Widget
	child_get_property (Widget *child, String property_name, Value value) : none Gets the value of a child property for child* and container. Gets the value of a child property for child and container.

	child_notify (String *child_property) : none Emits a GtkWidget::child-notify signal for the child property child_property* on widget. Emits a GtkWidget::child-notify signal for the child property child_property on widget. This is the analogue of g_object_notify() for child properties. Parameters: String child_property Required (not null) class of widget's parent Returns: none	Gtk.Widget
	child_set_property (Widget *child, String property_name, Value value) : none Sets a child property for child* and container. Sets a child property for child and container. Parameters: Gtk.Widget child Required (not null) String property_name Required (not null) GObject.Value value Required (not null) Returns: none	Gtk.Container
	child_type () : Number Returns the type of the children supported by the container. Returns the type of the children supported by the container. Note that this may return G_TYPE_NONE to indicate that no more children can be added, e.g. for a GtkPaned which already has two children. Returns: Number	Gtk.Container
	class_path () : Object Same as gtk_widget_path(), but always uses the name of a widget's type, never uses a custom name set with gtk_widget_set_name(). Same as gtk_widget_path(), but always uses the name of a widget's type, never uses a custom name set with gtk_widget_set_name().

Creates a new PangoLayout with the appropriate font map, font description, and base direction for drawing text for this widget. If you keep a PangoLayout created in this way around, in order to notify the layout of changes to the base direction or font of this widget, you must call pango_layout_context_changed() in response to the GtkWidget::style-set and GtkWidget::direction-changed signals for the widget. Parameters: String text Required (not null) Returns: Pango.Layout	Gtk.Widget
	create_row_drag_icon (TreePath *path) : Gdk.Pixmap Creates a GdkPixmap* representation of the row at path. Creates a GdkPixmap representation of the row at path. This image is used for a drag icon. Parameters: Gtk.TreePath path Required (not null) Returns: Gdk.Pixmap	Gtk.TreeView
	custom_finished (Builder *builder, Object child, String tagname, void *data) : none This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the buildable. This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the buildable. Parameters: Gtk.Builder builder* Required (not null) GObject.Object child child object or NULL for non-child tags String tagname Required (not null) void* data Required (not null) Returns: none	Gtk.Buildable
	custom_tag_end (Builder *builder, Object child, String tagname, void *data) : none This is called at the end of each custom element handled by the buildable.

This is called for each unknown element under <child>. if it doesn't. Parameters: Gtk.Builder builder* Required (not null) GObject.Object child child object or NULL for non-child tags String tagname Required (not null) GLib.MarkupParser parser Required (not null) void* data Required (not null) to parser functions Returns: Boolean	Gtk.Buildable
	destroy () : none Destroys a widget. Destroys a widget. Equivalent to gtk_object_destroy(), except that you don't have to cast the widget to GtkObject. When a widget is destroyed, it will break any references it holds to other objects. If the widget is inside a container, the widget will be removed from the container. If the widget is a toplevel (derived from GtkWindow), it will be removed from the list of toplevels, and the reference GTK+ holds to it will be removed. Removing a widget from its container or the list of toplevels results in the widget being finalized, unless you've added additional references to the widget with g_object_ref(). In most cases, only toplevel widgets (windows) require explicit destruction, because when you destroy a toplevel its children will be destroyed as well. Returns: none	Gtk.Widget
	destroyed (Widget *widget_pointer) : none This function sets widget_pointer to NULL if widget_pointer != NULL. This function sets *widget_pointer to NULL if widget_pointer != NULL. It's intended to be used as a callback connected to the "destroy" signal of a widget. You connect gtk_widget_destroyed() as a signal handler, and pass the address of your widget variable as user data. Then when the widget is destroyed, the variable will be set to NULL. Useful for example to avoid multiple copies of the same dialog. Parameters: Gtk.Widget widget_pointer Required (not null) address of a variable that contains widget Returns: none	Gtk.Widget
	draw (Rectangle *area) : none In GTK+ 1.2, this function would immediately render the region area* of a widget, by invoking the virtual draw method of a widget. In GTK+ 1.2, this function would immediately render the region area of a widget, by invoking the virtual draw method of a widget. In GTK+ 2.0, the draw method is gone, and instead gtk_widget_draw() simply invalidates the specified region of the widget, then updates the invalid region of the widget immediately. Usually you don't want to update the region immediately for performance reasons, so in general gtk_widget_queue_draw_area() is a better choice if you want to draw a region of a widget. Parameters: Gdk.Rectangle area Required (not null) Returns: none	Gtk.Widget
	enable_model_drag_dest (TargetEntry *targets, Number n_targets, DragAction actions) : none Turns tree_view* into a drop destination for automatic DND. Turns tree_view into a drop destination for automatic DND. Calling this method sets GtkTreeView:reorderable to FALSE. Parameters: Gtk.TargetEntry targets Required (not null) Number n_targets Required (not null) Gdk.DragAction actions Required (not null) widget Returns: none	Gtk.TreeView
	enable_model_drag_source (ModifierType *start_button_mask, TargetEntry targets, Number n_targets, DragAction actions) : none Turns tree_view* into a drag source for automatic DND. Turns tree_view into a drag source for automatic DND. Calling this method sets GtkTreeView:reorderable to FALSE. Parameters: Gdk.ModifierType start_button_mask Required (not null) Gtk.TargetEntry targets Required (not null) Number n_targets Required (not null) Gdk.DragAction actions Required (not null) widget Returns: none	Gtk.TreeView
	ensure_style () : none Ensures that widget has a style (widget->style). Ensures that widget has a style (widget->style). Not a very useful function; most of the time, if you want the style, the widget is realized, and realized widgets are guaranteed to have a style already. Returns: none	Gtk.Widget
	error_bell () : none Notifies the user about an input-related error on this widget. Notifies the user about an input-related error on this widget. If the GtkSettings:gtk-error-bell setting is TRUE, it calls gdk_window_beep(), otherwise it does nothing. Note that the effect of gdk_window_beep() can be configured in many ways, depending on the windowing backend and the desktop environment or window manager that is used. Returns: none	Gtk.Widget
	event (Event *event) : Boolean Rarely-used function. Rarely-used function. This function is used to emit the event signals on a widget (those signals should never be emitted without using this function to do so). If you want to synthesize an event though, don't use this function; instead, use gtk_main_do_event() so the event will behave as if it were in the event queue. Don't synthesize expose events; instead, use gdk_window_invalidate_rect() to invalidate a region of the window. the event was handled) Parameters: Gdk.Event event* Required (not null) Returns: Boolean	Gtk.Widget
	expand_all () : none Recursively expands all nodes in the tree_view. Recursively expands all nodes in the tree_view. Returns: none	Gtk.TreeView
	expand_row (TreePath *path, Boolean open_all) : Boolean Opens the row so its children are visible. Opens the row so its children are visible. Parameters: Gtk.TreePath path* Required (not null) Boolean open_all Required (not null) Returns: Boolean	Gtk.TreeView
	expand_to_path (TreePath *path) : none Expands the row at path. Expands the row at path. This will also expand all parent rows of Parameters: Gtk.TreePath path* Required (not null) Returns: none	Gtk.TreeView
	forall (Function *callback, void *callback_data) : none Invokes callback* on each child of container, including children that are considered "internal" (implementation details of the container). Invokes callback on each child of container, including children that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself. Most applications should use gtk_container_foreach(), rather than gtk_container_forall(). Parameters: Function (Widget *widget, void *data) : none Required (not null) void callback_data Required (not null) Returns: none	Gtk.Container
	foreach (Function *callback, void *callback_data) : none Invokes callback* on each non-internal child of container. Invokes callback on each non-internal child of container. See gtk_container_forall() for details on what constitutes an "internal" child. Most applications should use gtk_container_foreach(), rather than gtk_container_forall(). Parameters: Function (Widget *widget, void *data) : none Required (not null) void callback_data Required (not null) Returns: none	Gtk.Container
	foreach_full (Function *callback, Function marshal, void *callback_data, Function notify) : none Parameters: Function (Widget widget, void *data) : none Required (not null) Function (Object object, void *data, Number n_args, Arg args) : none Required (not null) void callback_data Required (not null) Function (void* *data*) : none Required (not null) Returns: none	Gtk.Container
	freeze_child_notify () : none Stops emission of GtkWidget::child-notify signals on widget. Stops emission of GtkWidget::child-notify signals on widget. The signals are queued until gtk_widget_thaw_child_notify() is called on widget. This is the analogue of g_object_freeze_notify() for child properties. Returns: none	Gtk.Widget
	get_accessible () : Atk.Object Returns the accessible object that describes the widget to an assistive technology. Returns the accessible object that describes the widget to an assistive technology. If no accessibility library is loaded (i.e. no ATK implementation library is loaded via GTK_MODULES or via another application library, such as libgnome), then this AtkObject instance may be a no-op. Likewise, if no class-specific AtkObject implementation is available for the widget instance in question, it will inherit an AtkObject implementation from the first ancestor class for which such an implementation is defined. The documentation of the ATK library contains more information about accessible objects and their uses. Returns: Atk.Object the AtkObject associated with widget	Gtk.Widget
	get_action () : Gtk.Action Returns the GtkAction that widget is a proxy for. Returns the GtkAction that widget is a proxy for. See also gtk_action_get_proxies(). NULL, if it is not attached to an action. Returns: Gtk.Action	Gtk.Widget
	get_allocation () : Gdk.Rectangle Retrieves the widget's allocation. Retrieves the widget's allocation. Returns: Gdk.Rectangle	Gtk.Widget
	get_ancestor (Number *widget_type) : Gtk.Widget Gets the first ancestor of widget* with type widget_type. Gets the first ancestor of widget with type widget_type. For example, gtk_widget_get_ancestor (widget, GTK_TYPE_BOX) gets the first GtkBox that's an ancestor of widget. No reference will be added to the returned widget; it should not be unreferenced. See note about checking for a toplevel GtkWindow in the docs for gtk_widget_get_toplevel(). Note that unlike gtk_widget_is_ancestor(), gtk_widget_get_ancestor() considers widget to be an ancestor of itself. Parameters: Number widget_type Required (not null) Returns: Gtk.Widget the ancestor widget, or NULL if not found	Gtk.Widget
	get_app_paintable () : Boolean Determines whether the application intends to draw on the widget in an GtkWidget::expose-event handler. Determines whether the application intends to draw on the widget in an GtkWidget::expose-event handler. See gtk_widget_set_app_paintable() Returns: Boolean	Gtk.Widget
	get_background_area (TreePath *path, TreeViewColumn column, Rectangle rect) : none Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path* and the column specified by column. Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is NULL, or points to a node not found in the tree, the y and height fields of the rectangle will be filled with 0. If column is NULL, the x and width fields will be filled with 0. The returned rectangle is equivalent to the areas tile to cover the entire bin window. Contrast with the cell_area, returned by gtk_tree_view_get_cell_area(), which returns only the cell itself, excluding surrounding borders and the tree expander area. Parameters: Gtk.TreePath path a GtkTreePath for the row, or NULL to get only horizontal coordinates Gtk.TreeViewColumn column a GtkTreeViewColumn for the column, or NULL to get only vertical coordiantes Gdk.Rectangle rect Required (not null) Returns: none	Gtk.TreeView
	get_bin_window () : Gdk.Window Returns the window that tree_view renders to. Returns the window that tree_view renders to. This is used primarily to compare to event->window to confirm that the event on Returns: Gdk.Window	Gtk.TreeView
	get_border_width () : Number Retrieves the border width of the container. Retrieves the border width of the container. See gtk_container_set_border_width(). Returns: Number	Gtk.Container
	get_can_default () : Boolean Determines whether widget can be a default widget. Determines whether widget can be a default widget. See gtk_widget_set_can_default(). Returns: Boolean	Gtk.Widget
	get_can_focus () : Boolean Determines whether widget can own the input focus. Determines whether widget can own the input focus. See gtk_widget_set_can_focus(). Returns: Boolean	Gtk.Widget
	get_cell_area (TreePath *path, TreeViewColumn column, Rectangle rect) : none Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path* and the column specified by column. Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is NULL, or points to a path not currently displayed, the y and height fields of the rectangle will be filled with 0. If column is NULL, the x and width fields will be filled with 0. The sum of all cell rects does not cover the entire tree; there are extra pixels in between rows, for example. The returned rectangle is equivalent to the cell_area passed to gtk_cell_renderer_render(). This function is only valid if tree_view is realized. Parameters: Gtk.TreePath path a GtkTreePath for the row, or NULL to get only horizontal coordinates Gtk.TreeViewColumn column a GtkTreeViewColumn for the column, or NULL to get only vertical coordinates Gdk.Rectangle rect Required (not null) Returns: none	Gtk.TreeView
	get_child_requisition (Requisition *requisition) : none This function is only for use in widget implementations. This function is only for use in widget implementations. Obtains geometry on the widget (e.g. with gtk_widget_set_size_request()), in which case it returns that geometry instead of the widget's requisition. This function differs from gtk_widget_size_request() in that it retrieves the last size request value from widget->requisition, while gtk_widget_size_request() actually calls the "size_request" method on widget* to compute the size request and fill in widget->requisition, and only then returns widget->requisition.

	get_snapshot (Rectangle *clip_rect) : Gdk.Pixmap Create a GdkPixmap* of the contents of the widget and its children. Create a GdkPixmap of the contents of the widget and its children. Works even if the widget is obscured. The depth and visual of the resulting pixmap is dependent on the widget being snapshot and likely differs from those of a target widget displaying the pixmap. The function gdk_pixbuf_get_from_drawable() can be used to convert the pixmap to a visual independant representation. The snapshot area used by this function is the widget's allocation plus any extra space occupied by additional windows belonging to this widget (such as the arrows of a spin button). Thus, the resulting snapshot pixmap is possibly larger than the allocation. If clip_rect is non-NULL, the resulting pixmap is shrunken to match the specified clip_rect. The (x,y) coordinates of clip_rect are interpreted widget relative. If width or height of clip_rect are 0 or negative, the width or height of the resulting pixmap will be shrunken by the respective amount. For instance a clip_rect { +5, +5, -10, -10 } will chop off 5 pixels at each side of the snapshot pixmap. If non-NULL, clip_rect will contain the exact widget-relative snapshot coordinates upon return. A clip_rect of { -1, -1, 0, 0 } can be used to preserve the auto-grown snapshot area and use clip_rect as a pure output parameter. The returned pixmap can be NULL, if the resulting clip_area was empty. Parameters: Gdk.Rectangle clip_rect a GdkRectangle or NULL Returns: Gdk.Pixmap	Gtk.Widget

This function returns the topmost widget in the container hierarchy returned as the topmost widget. No reference will be added to the returned widget; it should not be unreferenced. Note the difference in behavior vs. gtk_widget_get_ancestor(); gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW) would return NULL if widget wasn't inside a toplevel window, and if the window was inside a GtkWindow-derived widget which was in turn inside the toplevel GtkWindow. While the second case may seem unlikely, it actually happens when a GtkPlug is embedded inside a GtkSocket within the same application. To reliably find the toplevel GtkWindow, use gtk_widget_get_toplevel() and check if the TOPLEVEL flags is set on the result. \|[ GtkWidget toplevel = gtk_widget_get_toplevel (widget); if (gtk_widget_is_toplevel (toplevel)) { / Perform action on toplevel. / } ]\| if there's no ancestor.

Computes the intersection of a widget's area and area, storing the intersection in intersection, and returns TRUE if there was an intersection. intersection may be NULL if you're only interested in whether there was an intersection. Parameters: Gdk.Rectangle area Required (not null) Gdk.Rectangle intersection Required (not null) Returns: Boolean	Gtk.Widget
	is_ancestor (Widget *ancestor) : Boolean Determines whether widget* is somewhere inside ancestor, possibly with intermediate containers. Determines whether widget is somewhere inside ancestor, possibly with intermediate containers. grandchild, great grandchild, etc. Parameters: Gtk.Widget ancestor Required (not null) Returns: Boolean	Gtk.Widget
	is_composited () : Boolean Whether widget can rely on having its alpha channel drawn correctly. Whether widget can rely on having its alpha channel drawn correctly. On X11 this function returns whether a compositing manager is running for widget's screen. Please note that the semantics of this call will change in the future if used on a widget that has a composited window in its hierarchy (as set by gdk_window_set_composited()). channel being drawn correctly. Returns: Boolean	Gtk.Widget
	is_drawable () : Boolean Determines whether widget can be drawn to. Determines whether widget can be drawn to. A widget can be drawn to if it is mapped and visible. Returns: Boolean	Gtk.Widget
	is_focus () : Boolean Determines if the widget is the focus widget within its toplevel. Determines if the widget is the focus widget within its toplevel. (This does not mean that the HAS_FOCUS flag is necessarily set; HAS_FOCUS will only be set if the toplevel widget additionally has the global input focus.) Returns: Boolean	Gtk.Widget
	is_rubber_banding_active () : Boolean Returns whether a rubber banding operation is currently being done in tree_view. Returns whether a rubber banding operation is currently being done in tree_view. done in tree_view. Returns: Boolean	Gtk.TreeView
	is_sensitive () : Boolean Returns the widget's effective sensitivity, which means it is sensitive itself and also its parent widget is sensntive Returns the widget's effective sensitivity, which means it is sensitive itself and also its parent widget is sensntive Returns: Boolean	Gtk.Widget
	is_toplevel () : Boolean Determines whether widget is a toplevel widget. Determines whether widget is a toplevel widget. Currently only GtkWindow and GtkInvisible are toplevel widgets. Toplevel widgets have no parent widget. Returns: Boolean	Gtk.Widget
	keynav_failed (DirectionType *direction) : Boolean This function should be called whenever keyboard navigation within a single widget hits a boundary. This function should be called whenever keyboard navigation within a single widget hits a boundary. The function emits the GtkWidget::keynav-failed signal on the widget and its return value should be interpreted in a way similar to the return value of gtk_widget_child_focus(): When TRUE* is returned, stay in the widget, the failed keyboard navigation is Ok and/or there is nowhere we can/should move the focus to. When FALSE is returned, the caller should continue with keyboard navigation outside the widget, e.g. by calling gtk_widget_child_focus() on the widget's toplevel. The default ::keynav-failed handler returns TRUE for GTK_DIR_TAB_FORWARD and GTK_DIR_TAB_BACKWARD. For the other values of GtkDirectionType, it looks at the GtkSettings:gtk-keynav-cursor-only setting and returns FALSE if the setting is TRUE. This way the entire user interface becomes cursor-navigatable on input devices such as mobile phones which only have cursor keys but no tab key. Whenever the default handler returns TRUE, it also calls gtk_widget_error_bell() to notify the user of the failed keyboard navigation. A use case for providing an own implementation of ::keynav-failed (either by connecting to it or by overriding it) would be a row of GtkEntry widgets where the user should be able to navigate the entire row with the cursor keys, as e.g. known from user interfaces that require entering license keys. if the emitting widget should try to handle the keyboard navigation attempt in its parent container(s). Parameters: Gtk.DirectionType direction Required (not null) Returns: Boolean	Gtk.Widget
	list_mnemonic_labels () : Array Returns a newly allocated list of the widgets, normally labels, for which this widget is a the target of a mnemonic (see for example, gtk_label_set_mnemonic_widget()). Returns a newly allocated list of the widgets, normally labels, for which this widget is a the target of a mnemonic (see for example, gtk_label_set_mnemonic_widget()). The widgets in the list are not individually referenced. If you want to iterate through the list and perform actions involving callbacks that might destroy the widgets, you must call g_list_foreach (result, (GFunc)g_object_ref, NULL) first, and then unref all the widgets afterwards. mnemonic labels; free this list with g_list_free() when you are done with it. Returns: Array the list of	Gtk.Widget
	map () : none This function is only for use in widget implementations. This function is only for use in widget implementations. Causes a widget to be mapped if it isn't already. Returns: none	Gtk.Widget
	map_expanded_rows (Function *func, void *data) : none Calls func* on all expanded rows. Calls func on all expanded rows. Parameters: Function (TreeView *tree_view, TreePath path, void *user_data) : none Required (not null) void data Required (not null) Returns: none	Gtk.TreeView
	mnemonic_activate (Boolean *group_cycling) : Boolean Emits the GtkWidget::mnemonic-activate signal. Emits the GtkWidget::mnemonic-activate signal. The default handler for this signal activates the widget* if is TRUE. Parameters: Boolean group_cycling Required (not null) Returns: Boolean	Gtk.Widget
	modify_base (StateType *state, Color color) : none Sets the base color for a widget in a particular state. Sets the base color for a widget in a particular state. All other style values are left untouched. The base color is the background color used along with the text color (see gtk_widget_modify_text()) for widgets such as GtkEntry* and GtkTextView. See also gtk_widget_modify_style(). Note that "no window" widgets (which have the GTK_NO_WINDOW flag set) draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. GtkLabel. To modify the background of such widgets, you have to set the base color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a GtkEventBox widget and setting the base color on that. Parameters: Gtk.StateType state Required (not null) Gdk.Color color or NULL to undo the effect of previous calls to of gtk_widget_modify_base(). Returns: none	Gtk.Widget
	modify_bg (StateType *state, Color color) : none Sets the background color for a widget in a particular state. Sets the background color for a widget in a particular state. All other style values are left untouched. See also gtk_widget_modify_style(). Note that "no window" widgets (which have the GTK_NO_WINDOW* flag set) draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. GtkLabel. To modify the background of such widgets, you have to set the background color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a GtkEventBox widget and setting the background color on that. Parameters: Gtk.StateType state Required (not null) Gdk.Color color or NULL to undo the effect of previous calls to of gtk_widget_modify_bg(). Returns: none	Gtk.Widget
	modify_cursor (Color *primary, Color secondary) : none Sets the cursor color to use in a widget, overriding the GtkWidget:cursor-color and GtkWidget:secondary-cursor-color style properties. Sets the cursor color to use in a widget, overriding the GtkWidget:cursor-color and GtkWidget:secondary-cursor-color style properties. All other style values are left untouched. See also gtk_widget_modify_style(). Parameters: Gdk.Color primary* Required (not null) allocated), or NULL to undo the effect of previous calls to of gtk_widget_modify_cursor(). Gdk.Color secondary Required (not null) allocated), or NULL to undo the effect of previous calls to of gtk_widget_modify_cursor(). Returns: none	Gtk.Widget
	modify_fg (StateType *state, Color color) : none Sets the foreground color for a widget in a particular state. Sets the foreground color for a widget in a particular state. All other style values are left untouched. See also gtk_widget_modify_style(). Parameters: Gtk.StateType state* Required (not null) Gdk.Color color or NULL to undo the effect of previous calls to of gtk_widget_modify_fg(). Returns: none	Gtk.Widget
	modify_font (FontDescription *font_desc) : none Sets the font to use for a widget. Sets the font to use for a widget. All other style values are left untouched. See also gtk_widget_modify_style(). Parameters: Pango.FontDescription font_desc* the font description to use, or NULL to undo the effect of previous calls to gtk_widget_modify_font(). Returns: none	Gtk.Widget
	modify_style (RcStyle *style) : none Modifies style values on the widget. Modifies style values on the widget. Modifications made using this technique take precedence over style values set via an RC file, however, they will be overriden if a style is explicitely set on the widget using gtk_widget_set_style(). The GtkRcStyle* structure is designed so each field can either be set or unset, so it is possible, using this function, to modify some style values and leave the others unchanged. Note that modifications made with this function are not cumulative with previous calls to gtk_widget_modify_style() or with such functions as gtk_widget_modify_fg(). If you wish to retain previous values, you must first call gtk_widget_get_modifier_style(), make your modifications to the returned style, then call gtk_widget_modify_style() with that style. On the other hand, if you first call gtk_widget_modify_style(), subsequent calls to such functions gtk_widget_modify_fg() will have a cumulative effect with the initial modifications. Parameters: Gtk.RcStyle style Required (not null) Returns: none	Gtk.Widget
	modify_text (StateType *state, Color color) : none Sets the text color for a widget in a particular state. Sets the text color for a widget in a particular state. All other style values are left untouched. The text color is the foreground color used along with the base color (see gtk_widget_modify_base()) for widgets such as GtkEntry* and GtkTextView. See also gtk_widget_modify_style(). Parameters: Gtk.StateType state Required (not null) Gdk.Color color or NULL to undo the effect of previous calls to of gtk_widget_modify_text(). Returns: none	Gtk.Widget
	move_column_after (TreeViewColumn *column, TreeViewColumn base_column) : none Moves column* to be after to base_column. Moves column to be after to base_column. If base_column is NULL, then Parameters: Gtk.TreeViewColumn column Required (not null) Gtk.TreeViewColumn base_column The GtkTreeViewColumn to be moved relative to, or NULL. Returns: none	Gtk.TreeView
	parser_finished (Builder *builder) : none Called when the builder finishes the parsing of a GtkBuilder UI definition. Called when the builder finishes the parsing of a GtkBuilder UI definition. Note that this will be called once for each time gtk_builder_add_from_file() or gtk_builder_add_from_string() is called on a builder. Parameters: Gtk.Builder builder* Required (not null) Returns: none	Gtk.Buildable
	path () : Object Obtains the full path to widget. Obtains the full path to widget. The path is simply the name of a widget and all its parents in the container hierarchy, separated by periods. The name of a widget comes from gtk_widget_get_name(). Paths are used to apply styles to a widget in gtkrc configuration files. Widget names are the type of the widget by default (e.g. "GtkButton") or can be set to an application-specific value with gtk_widget_set_name(). By setting the name of a widget, you allow users or theme authors to apply styles to that specific widget in their gtkrc file. path_reversed_p fills in the path in reverse order, i.e. starting with widget's name instead of starting with the name of widget's outermost ancestor. Returns: path_length: Number path: String path_reversed: String	Gtk.Widget
	propagate_expose (Widget *child, EventExpose event) : none When a container receives an expose event, it must send synthetic expose events to all children that don't have their own GdkWindows. When a container receives an expose event, it must send synthetic expose events to all children that don't have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives an expose event, calls gtk_container_propagate_expose() once for each child, passing in the event the container received. gtk_container_propagate_expose() takes care of deciding whether an expose event needs to be sent to the child, intersecting the event's area with the child area, and sending the event. In most cases, a container can simply either simply inherit the GtkWidget::expose implementation from GtkContainer, or, do some drawing and then chain to the ::expose implementation from GtkContainer. Parameters: Gtk.Widget child* Required (not null) Gdk.EventExpose event Required (not null) Returns: none	Gtk.Container
	queue_clear () : none This function does the same as gtk_widget_queue_draw(). This function does the same as gtk_widget_queue_draw(). Returns: none	Gtk.Widget
	queue_clear_area (Number x, Number y, Number *width, Number height) : none This function is no longer different from gtk_widget_queue_draw_area(), though it once was. This function is no longer different from gtk_widget_queue_draw_area(), though it once was. Now it just calls gtk_widget_queue_draw_area(). Originally gtk_widget_queue_clear_area() would force a redraw of the background for GTK_NO_WINDOW* widgets, and gtk_widget_queue_draw_area() would not. Now both functions ensure the background will be redrawn. Parameters: Number x Required (not null) Number y Required (not null) Number width Required (not null) Number height Required (not null) Returns: none	Gtk.Widget
	queue_draw () : none Equivalent to calling gtk_widget_queue_draw_area() for the entire area of a widget. Equivalent to calling gtk_widget_queue_draw_area() for the entire area of a widget. Returns: none	Gtk.Widget
	queue_draw_area (Number x, Number y, Number *width, Number height) : none Invalidates the rectangular area of widget* defined by x, y, widget's window and all its child windows. Invalidates the rectangular area of widget defined by x, y, widget's window and all its child windows. Once the main loop becomes idle (after the current batch of events has been processed, roughly), the window will receive expose events for the union of all regions that have been invalidated. Normally you would only use this function in widget implementations. You might also use it, or gdk_window_invalidate_rect() directly, to schedule a redraw of a GtkDrawingArea or some portion thereof. Frequently you can just call gdk_window_invalidate_rect() or gdk_window_invalidate_region() instead of this function. Those functions will invalidate only a single window, instead of the widget and all its children. The advantage of adding to the invalidated region compared to simply drawing immediately is efficiency; using an invalid region ensures that you only have to redraw one time. Parameters: Number x Required (not null) Number y Required (not null) Number width Required (not null) Number height Required (not null) Returns: none	Gtk.Widget
	queue_resize () : none This function is only for use in widget implementations. This function is only for use in widget implementations. Flags a widget to have its size renegotiated; should be called when a widget for some reason has a new size request. For example, when you change the text in a GtkLabel, GtkLabel queues a resize to ensure there's enough space for the new text. Returns: none	Gtk.Widget
	queue_resize_no_redraw () : none This function works like gtk_widget_queue_resize(), except that the widget is not invalidated. This function works like gtk_widget_queue_resize(), except that the widget is not invalidated. Returns: none	Gtk.Widget
	realize () : none Creates the GDK (windowing system) resources associated with a widget. Creates the GDK (windowing system) resources associated with a widget. For example, widget->window will be created when a widget is realized. Normally realization happens implicitly; if you show a widget and all its parent containers, then the widget will be realized and mapped automatically. Realizing a widget requires all the widget's parent widgets to be realized; calling gtk_widget_realize() realizes the widget's parents in addition to when you realize it, bad things will happen. This function is primarily used in widget implementations, and isn't very useful otherwise. Many times when you think you might need it, a better approach is to connect to a signal that will be called after the widget is realized automatically, such as GtkWidget::expose-event. Or simply g_signal_connect () to the GtkWidget::realize signal. Returns: none	Gtk.Widget
	ref_accessible () : Atk.Object Gets a reference to an object's AtkObject implementation, if the object implements AtkObjectIface Gets a reference to an object's AtkObject implementation, if the object implements AtkObjectIface Returns: Atk.Object	Atk.ImplementorIface
	region_intersect (Region *region) : Gdk.Region Computes the intersection of a widget's area and region, returning the intersection. Computes the intersection of a widget's area and region, returning the intersection. The result may be empty, use gdk_region_empty() to check. Parameters: Gdk.Region region* Required (not null) Returns: Gdk.Region and region. The coordinates of the return value are relative to widget->window for NO_WINDOW widgets, and relative to the parent window of widget->window for widgets with their own window.	Gtk.Widget
	remove (Widget *widget) : none Removes widget* from container. Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it while it's not inside a container, using g_object_ref(). If you don't want to use widget again it's usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles. Parameters: Gtk.Widget widget Required (not null) Returns: none	Gtk.Container
	remove_accelerator (AccelGroup *accel_group, Number accel_key, ModifierType accel_mods) : Boolean Removes an accelerator from widget, previously installed with gtk_widget_add_accelerator(). Removes an accelerator from widget, previously installed with gtk_widget_add_accelerator(). Parameters: Gtk.AccelGroup accel_group* Required (not null) Number accel_key Required (not null) Gdk.ModifierType accel_mods Required (not null) Returns: Boolean	Gtk.Widget
	remove_column (TreeViewColumn *column) : Number Removes column* from tree_view. Removes column from tree_view. Parameters: Gtk.TreeViewColumn column Required (not null) Returns: Number	Gtk.TreeView
	remove_data (String *key) : none Parameters: String key* Required (not null) Returns: none	Gtk.Object
	remove_data_by_id (Number *data_id) : none Parameters: Number data_id* Required (not null) Returns: none	Gtk.Object
	remove_mnemonic_label (Widget *label) : none Removes a widget from the list of mnemonic labels for this widget. Removes a widget from the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). The widget must have previously been added to the list with gtk_widget_add_mnemonic_label(). Parameters: Gtk.Widget label* Required (not null) Returns: none	Gtk.Widget
	remove_no_notify (String *key) : none Parameters: String key* Required (not null) Returns: none	Gtk.Object
	remove_no_notify_by_id (Number *key_id) : none Parameters: Number key_id* Required (not null) Returns: none	Gtk.Object
	render_icon (String *stock_id, Number size, String detail) : GdkPixbuf.Pixbuf A convenience function that uses the theme engine and RC file settings for widget* to look up stock_id and render it to a pixbuf. A convenience function that uses the theme engine and RC file settings for widget to look up stock_id and render it to a pixbuf. stock_id should be a stock icon ID such as GTK_STOCK_OPEN or GTK_STOCK_OK. size should be a size such as GTK_ICON_SIZE_MENU. detail should be a string that identifies the widget or code doing the rendering, so that theme engines can special-case rendering for that widget or code. The pixels in the returned GdkPixbuf are shared with the rest of the application and should not be modified. The pixbuf should be freed after use with g_object_unref(). Parameters: String stock_id Required (not null) Number size Required (not null) 1 means render at the size of the source and don't scale (if there are multiple source sizes, GTK+ picks one of the available sizes). String detail render detail to pass to theme engine Returns: GdkPixbuf.Pixbuf	Gtk.Widget
	reparent (Widget *new_parent) : none Moves a widget from one GtkContainer* to another, handling reference count issues to avoid destroying the widget. Moves a widget from one GtkContainer to another, handling reference count issues to avoid destroying the widget. Parameters: Gtk.Widget new_parent Required (not null) Returns: none	Gtk.Widget
	reset_rc_styles () : none Reset the styles of widget and all descendents, so when they are looked up again, they get the correct values for the currently loaded RC file settings. Reset the styles of widget and all descendents, so when they are looked up again, they get the correct values for the currently loaded RC file settings. This function is not useful for applications. Returns: none	Gtk.Widget
	reset_shapes () : none Recursively resets the shape on this widget and its descendants. Recursively resets the shape on this widget and its descendants. Returns: none	Gtk.Widget
	resize_children () : none Returns: none	Gtk.Container
	row_activated (TreePath *path, TreeViewColumn column) : none Activates the cell determined by path* and column. Activates the cell determined by path and column. Parameters: Gtk.TreePath path Required (not null) Gtk.TreeViewColumn column Required (not null) Returns: none	Gtk.TreeView
	row_expanded (TreePath *path) : Boolean Returns TRUE* if the node pointed to by path is expanded in tree_view. Returns TRUE if the node pointed to by path is expanded in tree_view. Parameters: Gtk.TreePath path Required (not null) Returns: Boolean	Gtk.TreeView
	scroll_to_cell (TreePath *path, TreeViewColumn column, Boolean use_align, Number row_align, Number col_align) : none Moves the alignments of tree_view* to the position specified by column and if path is NULL no vertical scrolling occurs. Moves the alignments of tree_view to the position specified by column and if path is NULL no vertical scrolling occurs. At a minimum, one of column or path need to be non-NULL. row_align determines where the row is placed, and col_align determines where column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center. If use_align is FALSE, then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the cell onto the screen. This means that the cell will be scrolled to the edge closest to its current position. If the cell is currently visible on the screen, nothing is done. This function only works if the model is set, and path is a valid row on the model. If the model changes before the tree_view is realized, the centered path will be modified to reflect this change. Parameters: Gtk.TreePath path The path of the row to move to, or NULL. Gtk.TreeViewColumn column The GtkTreeViewColumn to move horizontally to, or NULL. Boolean use_align Required (not null) Number row_align Required (not null) Number col_align Required (not null) Returns: none	Gtk.TreeView
	scroll_to_point (Number *tree_x, Number tree_y) : none Scrolls the tree view such that the top-left corner of the visible area is tree_x, tree_y, where tree_x* and tree_y are specified in tree coordinates. Scrolls the tree view such that the top-left corner of the visible area is tree_x, tree_y, where tree_x and tree_y are specified in tree coordinates. The tree_view must be realized before this function is called. If it isn't, you probably want to be using gtk_tree_view_scroll_to_cell(). If either tree_x or tree_y are -1, then that direction isn't scrolled. Parameters: Number tree_x Required (not null) Number tree_y Required (not null) Returns: none	Gtk.TreeView
	send_expose (Event *event) : Number Very rarely-used function. Very rarely-used function. This function is used to emit an expose event signals on a widget. This function is not normally used directly. The only time it is used is when propagating an expose event to a child NO_WINDOW* widget, and that is normally done using gtk_container_propagate_expose(). If you want to force an area of a window to be redrawn, use gdk_window_invalidate_rect() or gdk_window_invalidate_region(). To cause the redraw to be done immediately, follow that call with a call to gdk_window_process_updates(). the event was handled) Parameters: Gdk.Event event Required (not null) Returns: Number	Gtk.Widget
	send_focus_change (Event *event) : Boolean Sends the focus change event* to widget This function is not meant to be used by applications. Sends the focus change event to widget This function is not meant to be used by applications. The only time it should be used is when it is necessary for a GtkWidget to assign focus to a widget that is semantically owned by the first widget even though it's not a direct child - for instance, a search entry in a floating window similar to the quick search in GtkTreeView. An example of its usage is: \|[ GdkEvent fevent = gdk_event_new (GDK_FOCUS_CHANGE); fevent->focus_change.type = GDK_FOCUS_CHANGE; fevent->focus_change.in = TRUE; fevent->focus_change.window = gtk_widget_get_window (widget); if (fevent->focus_change.window != NULL) g_object_ref (fevent->focus_change.window); gtk_widget_send_focus_change (widget, fevent); gdk_event_free (event); ]\| if the event was handled, and FALSE* otherwise Parameters: Gdk.Event event Required (not null) Returns: Boolean	Gtk.Widget
	set_accel_path (String *accel_path, AccelGroup accel_group) : none Given an accelerator group, accel_group, and an accelerator path, key binding that is defined for accel_path* is pressed, widget will be activated. Given an accelerator group, accel_group, and an accelerator path, key binding that is defined for accel_path is pressed, widget will be activated. This removes any accelerators (for any accelerator group) installed by previous calls to gtk_widget_set_accel_path(). Associating accelerators with paths allows them to be modified by the user and the modifications to be saved for future use. (See gtk_accel_map_save().) This function is a low level function that would most likely be used by a menu creation system like GtkUIManager. If you use GtkUIManager, setting up accelerator paths will be done automatically. Even when you you aren't using GtkUIManager, if you only want to set up accelerators on menu items gtk_menu_item_set_accel_path() provides a somewhat more convenient interface. Note that accel_path string will be stored in a GQuark. Therefore, if you pass a static string, you can save some memory by interning it first with g_intern_static_string(). Parameters: String accel_path path used to look up the accelerator Gtk.AccelGroup accel_group a GtkAccelGroup. Returns: none	Gtk.Widget
	set_allocation (Rectangle *allocation) : none Sets the widget's allocation. Sets the widget's allocation. This should not be used directly, but from within a widget's size_allocate method. Parameters: Gdk.Rectangle allocation* Required (not null) Returns: none	Gtk.Widget
	set_app_paintable (Boolean *app_paintable) : none Sets whether the application intends to draw on the widget in an GtkWidget::expose-event handler. Sets whether the application intends to draw on the widget in an GtkWidget::expose-event handler. This is a hint to the widget and does not affect the behavior of the GTK+ core; many widgets ignore this flag entirely. For widgets that do pay attention to the flag, such as GtkEventBox* and GtkWindow, the effect is to suppress default themed drawing of the widget's background. (Children of the widget will still be drawn.) The application is then entirely responsible for drawing the widget background. Note that the background is still drawn when the widget is mapped. If this is not suitable (e.g. because you want to make a transparent window using an RGBA visual), you can work around this by doing: \|[ gtk_widget_realize (window); gdk_window_set_back_pixmap (window->window, NULL, FALSE); gtk_widget_show (window); ]\| Parameters: Boolean app_paintable Required (not null) Returns: none	Gtk.Widget
	set_border_width (Number *border_width) : none Sets the border width of the container. Sets the border width of the container. The border width of a container is the amount of space to leave around the outside of the container. The only exception to this is GtkWindow; because toplevel windows can't leave space outside, they leave the space inside. The border is added on all sides of the container. To add space to only one side, one approach is to create a GtkAlignment* widget, call gtk_widget_set_size_request() to give it a size, and place it on the side of the container as a spacer. Parameters: Number border_width Required (not null) the container. Valid values are in the range 0-65535 pixels. Returns: none	Gtk.Container
	set_buildable_property (Builder *builder, String name, Value value) : none Sets the property name name* to value on the buildable object. Sets the property name name to value on the buildable object. Parameters: Gtk.Builder builder Required (not null) String name Required (not null) GObject.Value value Required (not null) Returns: none	Gtk.Buildable
	set_can_default (Boolean *can_default) : none Specifies whether widget* can be a default widget. Specifies whether widget can be a default widget. See gtk_widget_grab_default() for details about the meaning of "default". Parameters: Boolean can_default Required (not null) Returns: none	Gtk.Widget
	set_can_focus (Boolean *can_focus) : none Specifies whether widget* can own the input focus. Specifies whether widget can own the input focus. See gtk_widget_grab_focus() for actually setting the input focus on a widget. Parameters: Boolean can_focus Required (not null) Returns: none	Gtk.Widget
	set_child_visible (Boolean *is_visible) : none Sets whether widget* should be mapped along with its when its parent is mapped and widget has been shown with gtk_widget_show(). Sets whether widget should be mapped along with its when its parent is mapped and widget has been shown with gtk_widget_show(). The child visibility can be set for widget before it is added to a container with gtk_widget_set_parent(), to avoid mapping children unnecessary before immediately unmapping them. However it will be reset to its default state of TRUE when the widget is removed from a container. Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself. This function is only useful for container implementations and never should be called by an application. Parameters: Boolean is_visible Required (not null) Returns: none	Gtk.Widget
	set_colormap (Colormap *colormap) : none Sets the colormap for the widget to the given value. Sets the colormap for the widget to the given value. Widget must not have been previously realized. This probably should only be used from an init() function (i.e. from the constructor for the widget). Parameters: Gdk.Colormap colormap* Required (not null) Returns: none	Gtk.Widget
	set_column_drag_function (Function *func, void *user_data, Function destroy) : none Sets a user function for determining where a column may be dropped when dragged. Sets a user function for determining where a column may be dropped when dragged. This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The dragged, the two GtkTreeViewColumn* s determining the drop spot, and are NULL, then they indicate an edge. If func is set to be NULL, then dropped everywhere.

	set_cursor (TreePath *path, TreeViewColumn focus_column, Boolean start_editing) : none Sets the current keyboard focus to be at path, and selects it. Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user's attention on a particular row. If it. Additionally, if focus_column* is specified, and start_editing is TRUE, then editing should be started in the specified cell. This function is often followed by gtk_widget_grab_focus (tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized. If path is invalid for model, the current cursor (if any) will be unset and the function will return without failing. Parameters: Gtk.TreePath path Required (not null) Gtk.TreeViewColumn focus_column A GtkTreeViewColumn, or NULL Boolean start_editing Required (not null) Returns: none	Gtk.TreeView
	set_cursor_on_cell (TreePath *path, TreeViewColumn focus_column, CellRenderer focus_cell, Boolean start_editing) : none Sets the current keyboard focus to be at path, and selects it. Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user's attention on a particular row. If it. If focus_column* and focus_cell are not NULL, and focus_column contains 2 or more editable or activatable cells, then focus is given to the cell specified by focus_cell. Additionally, if focus_column is specified, and start_editing is TRUE, then editing should be started in the specified cell. This function is often followed by widget. Please note that editing can only happen when the widget is realized. If path is invalid for model, the current cursor (if any) will be unset and the function will return without failing.

It is meant for private use by ATK for determining the number of visible children that are removed when the user collapses a row, or a row is deleted. Parameters: Function (TreeView tree_view, TreePath path, Number children, void *user_data) : none Function to be called when a view row is destroyed, or NULL* void* data User data to be passed to func, or NULL Function (void* *data) : none Destroy notifier for data, or NULL* Returns: none	Gtk.TreeView
	set_direction (TextDirection *dir) : none Sets the reading direction on a particular widget. Sets the reading direction on a particular widget. This direction controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitely visual rather than logical (such as buttons for text justification). If the direction is set to GTK_TEXT_DIR_NONE, then the value set by gtk_widget_set_default_direction() will be used. Parameters: Gtk.TextDirection dir* Required (not null) Returns: none	Gtk.Widget
	set_double_buffered (Boolean *double_buffered) : none Widgets are double buffered by default; you can use this function to turn off the buffering. Widgets are double buffered by default; you can use this function to turn off the buffering. "Double buffered" simply means that gdk_window_begin_paint_region() and gdk_window_end_paint() are called automatically around expose events sent to the widget. gdk_window_begin_paint() diverts all drawing to a widget's window to an offscreen buffer, and gdk_window_end_paint() draws the buffer to the screen. The result is that users see the window update in one smooth step, and don't see individual graphics primitives being rendered. In very simple terms, double buffered widgets don't flicker, so you would only use this function to turn off double buffering if you had special needs and really knew what you were doing. expose events, since even the clearing to the background color or pixmap will not happen automatically (as it is done in gdk_window_begin_paint()). Parameters: Boolean double_buffered* Required (not null) Returns: none	Gtk.Widget
	set_drag_dest_row (TreePath *path, TreeViewDropPosition pos) : none Sets the row that is highlighted for feedback. Sets the row that is highlighted for feedback.

	set_enable_search (Boolean *enable_search) : none If enable_search* is set, then the user can type in text to search through the tree interactively (this is sometimes called "typeahead find"). If enable_search is set, then the user can type in text to search through the tree interactively (this is sometimes called "typeahead find"). Note that even if this is FALSE, the user can still initiate a search using the "start-interactive-search" key binding. Parameters: Boolean enable_search Required (not null) Returns: none	Gtk.TreeView
	set_enable_tree_lines (Boolean *enabled) : none Sets whether to draw lines interconnecting the expanders in tree_view. Sets whether to draw lines interconnecting the expanders in tree_view.

The event mask determines which events a widget will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget's functionality, so be careful. This function must be called while a widget is unrealized. Consider gtk_widget_add_events() for widgets that are already realized, or if you want to preserve the existing event mask. This function can't be used with GTK_NO_WINDOW* widgets; to get events on those widgets, place them inside a GtkEventBox and receive events on the event box. Parameters: Number events Required (not null) Returns: none	Gtk.Widget
	set_expander_column (TreeViewColumn *column) : none Sets the column to draw the expander arrow at. Sets the column to draw the expander arrow at. It must be in tree_view. If column* is NULL, then the expander arrow is always at the first visible column. If you do not want expander arrow to appear in your tree, set the expander column to a hidden column. Parameters: Gtk.TreeViewColumn column Required (not null) Returns: none	Gtk.TreeView

Only enable this option if all rows are the same height and all columns are of type GTK_TREE_VIEW_COLUMN_FIXED. Parameters: Boolean enable Required (not null) Returns: none	Gtk.TreeView
	set_focus_child (Widget *child) : none Sets, or unsets if child* is NULL, the focused child of container. Sets, or unsets if child is NULL, the focused child of container. This function emits the GtkContainer::set_focus_child signal of default behaviour by overriding the class closure of this signal. Parameters: Gtk.Widget child a GtkWidget, or NULL Returns: none	Gtk.Container
	set_focus_hadjustment (Adjustment *adjustment) : none Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_vadjustment() for setting the vertical adjustment. The adjustments have to be in pixel units and in the same coordinate system as the allocation for immediate children of the container. Parameters: Gtk.Adjustment adjustment* Required (not null) moved among the descendents of container Returns: none	Gtk.Container
	set_focus_vadjustment (Adjustment *adjustment) : none Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See gtk_scrolled_window_get_vadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_hadjustment() for setting the horizontal adjustment. The adjustments have to be in pixel units and in the same coordinate system as the allocation for immediate children of the container. Parameters: Gtk.Adjustment adjustment* Required (not null) is moved among the descendents of container Returns: none	Gtk.Container

	set_has_window (Boolean *has_window) : none Specifies whether widget* has a GdkWindow of its own. Specifies whether widget has a GdkWindow of its own. Note that all realized widgets have a non-NULL "window" pointer (gtk_widget_get_window() never returns a NULL window when a widget is realized), but for many of them it's actually the GdkWindow of one of its parent widgets. Widgets that create a window for themselves in GtkWidget::realize() however must announce this by calling this function with has_window = TRUE. This function should only be called by widget implementations, and they should call it in their init() function. Parameters: Boolean has_window Required (not null) Returns: none	Gtk.Widget
	set_headers_clickable (Boolean *setting) : none Allow the column title buttons to be clicked. Allow the column title buttons to be clicked. Parameters: Boolean setting* Required (not null) Returns: none	Gtk.TreeView

	set_hover_selection (Boolean *hover) : none Enables of disables the hover selection mode of tree_view. Enables of disables the hover selection mode of tree_view. Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes GTK_SELECTION_SINGLE* and GTK_SELECTION_BROWSE. Parameters: Boolean hover Required (not null) Returns: none	Gtk.TreeView
	set_level_indentation (Number *indentation) : none Sets the amount of extra indentation for child levels to use in tree_view* in addition to the default indentation. Sets the amount of extra indentation for child levels to use in tree_view in addition to the default indentation. The value should be specified in pixels, a value of 0 disables this feature and in this case only the default indentation will be used. This does not have any visible effects for lists. Parameters: Number indentation Required (not null) Returns: none	Gtk.TreeView
	set_mapped (Boolean *mapped) : none Marks the widget as being realized. Marks the widget as being realized. This function should only ever be called in a derived widget's "map" or "unmap" implementation. Parameters: Boolean mapped* Required (not null) Returns: none	Gtk.Widget
	set_model (TreeModel *model) : none Sets the model for a GtkTreeView. Sets the model for a GtkTreeView. If the tree_view* already has a model set, it will remove it before setting the new model. If model is NULL, then it will unset the old model. Parameters: Gtk.TreeModel model The model. Returns: none	Gtk.TreeView
	set_name (String *name) : none Widgets can be named, which allows you to refer to them from a gtkrc file. Widgets can be named, which allows you to refer to them from a gtkrc file. You can apply a style to widgets with a particular name in the gtkrc file. See the documentation for gtkrc files (on the same page as the docs for GtkRcStyle). Note that widget names are separated by periods in paths (see gtk_widget_path()), so names with embedded periods may cause confusion. Parameters: String name* Required (not null) Returns: none	Gtk.Widget
	set_no_show_all (Boolean *no_show_all) : none Sets the GtkWidget:no-show-all property, which determines whether calls to gtk_widget_show_all() and gtk_widget_hide_all() will affect this widget. Sets the GtkWidget:no-show-all property, which determines whether calls to gtk_widget_show_all() and gtk_widget_hide_all() will affect this widget. This is mostly for use in constructing widget hierarchies with externally controlled visibility, see GtkUIManager. Parameters: Boolean no_show_all* Required (not null) Returns: none	Gtk.Widget
	set_parent (Widget *parent) : none This function is useful only when implementing subclasses of GtkContainer. This function is useful only when implementing subclasses of GtkContainer. Sets the container as the parent of widget, and takes care of some details such as updating the state and style of the child to reflect its new location. The opposite function is gtk_widget_unparent(). Parameters: Gtk.Widget parent* Required (not null) Returns: none	Gtk.Widget
	set_parent_window (Window *parent_window) : none Sets a non default parent window for widget. Sets a non default parent window for widget. Parameters: Gdk.Window parent_window* Required (not null) Returns: none	Gtk.Widget
	set_realized (Boolean *realized) : none Marks the widget as being realized. Marks the widget as being realized. This function should only ever be called in a derived widget's "realize" or "unrealize" implementation. Parameters: Boolean realized* Required (not null) Returns: none	Gtk.Widget
	set_reallocate_redraws (Boolean *needs_redraws) : none Sets the reallocate_redraws* flag of the container to the given value. Sets the reallocate_redraws flag of the container to the given value. Containers requesting reallocation redraws get automatically redrawn if any of their children changed allocation. Parameters: Boolean needs_redraws Required (not null) Returns: none	Gtk.Container
	set_receives_default (Boolean *receives_default) : none Specifies whether widget* will be treated as the default widget within its toplevel when it has the focus, even if another widget is the default. Specifies whether widget will be treated as the default widget within its toplevel when it has the focus, even if another widget is the default. See gtk_widget_grab_default() for details about the meaning of "default". Parameters: Boolean receives_default Required (not null) Returns: none	Gtk.Widget
	set_redraw_on_allocate (Boolean *redraw_on_allocate) : none Sets whether the entire widget is queued for drawing when its size allocation changes. Sets whether the entire widget is queued for drawing when its size allocation changes. By default, this setting is TRUE* and the entire widget is redrawn on every size change. If your widget leaves the upper left unchanged when made bigger, turning this setting off will improve performance. Note that for NO_WINDOW widgets setting this flag to FALSE turns its position changes; this is to allow containers that don't draw anything to avoid excess invalidations. If you set this flag on a NO_WINDOW widget that does draw on widget->window, you are responsible for invalidating both the old and new allocation of the widget when the widget is moved and responsible for invalidating regions newly when the widget increases size. Parameters: Boolean redraw_on_allocate Required (not null) when it is allocated to a new size. Otherwise, only the new portion of the widget will be redrawn. Returns: none	Gtk.Widget
	set_reorderable (Boolean *reorderable) : none This function is a convenience function to allow you to reorder models that support the GtkDragSourceIface* and the GtkDragDestIface. This function is a convenience function to allow you to reorder models that support the GtkDragSourceIface and the GtkDragDestIface. Both GtkTreeStore and GtkListStore support these. If reorderable is TRUE, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model's row_inserted and row_deleted signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose. This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually. Parameters: Boolean reorderable Required (not null) Returns: none	Gtk.TreeView
	set_resize_mode (ResizeMode *resize_mode) : none Sets the resize mode for the container. Sets the resize mode for the container. The resize mode of a container determines whether a resize request will be passed to the container's parent, queued for later execution or executed immediately. Parameters: Gtk.ResizeMode resize_mode* Required (not null) Returns: none	Gtk.Container
	set_row_separator_func (Function *func, void *data, Function destroy) : none Sets the row separator function, which is used to determine whether a row should be drawn as a separator. Sets the row separator function, which is used to determine whether a row should be drawn as a separator. If the row separator function is NULL, no separators are drawn. This is the default value. Parameters: Function (TreeModel model, TreeIter iter, void *data) : none Required (not null) void data user data to pass to func, or NULL Function (void* *data) : none destroy notifier for data, or NULL* Returns: none	Gtk.TreeView
	set_rubber_banding (Boolean *enable) : none Enables or disables rubber banding in tree_view. Enables or disables rubber banding in tree_view. If the selection mode is GTK_SELECTION_MULTIPLE, rubber banding will allow the user to select multiple rows by dragging the mouse. Parameters: Boolean enable* Required (not null) Returns: none	Gtk.TreeView
	set_rules_hint (Boolean *setting) : none Parameters: Boolean setting* Required (not null) Returns: none	Gtk.TreeView
	set_scroll_adjustments (Adjustment *hadjustment, Adjustment vadjustment) : Boolean For widgets that support scrolling, sets the scroll adjustments and returns TRUE. For widgets that support scrolling, sets the scroll adjustments and returns TRUE. For widgets that don't support scrolling, does nothing and returns FALSE. Widgets that don't support scrolling can be scrolled by placing them in a GtkViewport, which does support scrolling. Parameters: Gtk.Adjustment hadjustment* an adjustment for horizontal scrolling, or NULL Gtk.Adjustment vadjustment an adjustment for vertical scrolling, or NULL Returns: Boolean	Gtk.Widget
	set_search_column (Number *column) : none Sets column* as the column where the interactive search code should search in for the current model. Sets column as the column where the interactive search code should search in for the current model. If the search column is set, users can use the "start-interactive-search" key binding to bring up search popup. The enable-search property controls whether simply typing text will also start an interactive search. Note that column refers to a column of the current model. The search column is reset to -1 when the model is changed. Parameters: Number column Required (not null) Returns: none	Gtk.TreeView
	set_search_entry (Entry *entry) : none Sets the entry which the interactive search code will use for this in our interface at all time at a fixed position. Sets the entry which the interactive search code will use for this in our interface at all time at a fixed position. Passing NULL* for entry again. Parameters: Gtk.Entry entry the entry the interactive search code of tree_view should use or NULL Returns: none	Gtk.TreeView
	set_search_equal_func (Function *search_equal_func, void *search_user_data, Function search_destroy) : none Sets the compare function for the interactive search capabilities; note that somewhat like strcmp() returning 0 for equality GtkTreeViewSearchEqualFunc* returns FALSE on matches. Sets the compare function for the interactive search capabilities; note that somewhat like strcmp() returning 0 for equality GtkTreeViewSearchEqualFunc returns FALSE on matches. Parameters: Function (TreeModel *model, Number column, String key, TreeIter iter, void *search_data) : none Required (not null) void search_user_data user data to pass to search_equal_func, or NULL Function (void* *data) : none Destroy notifier for search_user_data, or NULL* Returns: none	Gtk.TreeView
	set_search_position_func (Function *func, void *data, Function destroy) : none Sets the function to use when positioning the search dialog.

Parameters: Function (TreeView tree_view, Widget search_dialog, void *user_data) : none the function to use to position the search dialog, or NULL* to use the default search position function void* data user data to pass to func, or NULL Function (void* *data) : none Destroy notifier for data, or NULL* Returns: none	Gtk.TreeView
	set_sensitive (Boolean *sensitive) : none Sets the sensitivity of a widget. Sets the sensitivity of a widget. A widget is sensitive if the user can interact with it. Insensitive widgets are "grayed out" and the user can't interact with them. Insensitive widgets are known as "inactive", "disabled", or "ghosted" in some other toolkits. Parameters: Boolean sensitive* Required (not null) Returns: none	Gtk.Widget
	set_show_expanders (Boolean *enabled) : none Sets whether to draw and enable expanders and indent child rows in and there will be no way to expand and collapse rows by default. Sets whether to draw and enable expanders and indent child rows in and there will be no way to expand and collapse rows by default. Also note that hiding the expanders will disable the default indentation. You can set a custom indentation in this case using gtk_tree_view_set_level_indentation(). This does not have any visible effects for lists. Parameters: Boolean enabled* Required (not null) Returns: none	Gtk.TreeView
	set_size_request (Number *width, Number height) : none Sets the minimum size of a widget; that is, the widget's size request will be width* by height. Sets the minimum size of a widget; that is, the widget's size request will be width by height. You can use this function to force a widget to be either larger or smaller than it normally would be. In most cases, gtk_window_set_default_size() is a better choice for toplevel windows than this function; setting the default size will still allow users to shrink the window. Setting the size request will force them to leave the window at least as large as the size request. When dealing with window sizes, gtk_window_set_geometry_hints() can be a useful function as well. Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hardcode a size that will always be correct. The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it requested. If the size request in a given direction is -1 (unset), then the "natural" size request of the widget will be used instead. Widgets can't actually be allocated a size less than 1 by 1, but you can pass 0,0 to this function to mean "as small as possible." Parameters: Number width Required (not null) Number height Required (not null) Returns: none	Gtk.Widget
	set_state (StateType *state) : none This function is for use in widget implementations. This function is for use in widget implementations. Sets the state of a widget (insensitive, prelighted, etc.) Usually you should set the state using wrapper functions such as gtk_widget_set_sensitive(). Parameters: Gtk.StateType state* Required (not null) Returns: none	Gtk.Widget
	set_style (Style *style) : none Sets the GtkStyle* for a widget (widget->style). Sets the GtkStyle for a widget (widget->style). You probably don't want to use this function; it interacts badly with themes, because themes work by replacing the GtkStyle. Instead, use gtk_widget_modify_style(). Parameters: Gtk.Style style a GtkStyle, or NULL to remove the effect of a previous gtk_widget_set_style() and go back to the default style Returns: none	Gtk.Widget
	set_tooltip_cell (Tooltip *tooltip, TreePath path, TreeViewColumn column, CellRenderer cell) : none Sets the tip area of tooltip* to the area path, column and cell have in common. Sets the tip area of tooltip to the area path, column and cell have in common. For example if path is NULL and column is set, the tip area will be set to the full area covered by column. See also gtk_tooltip_set_tip_area(). Note that if path is not specified and cell is set and part of a column containing the expander, the tooltip might not show and hide at the correct position. In such cases path must be set to the current node under the mouse cursor for this function to operate correctly. See also gtk_tree_view_set_tooltip_column() for a simpler alternative. Parameters: Gtk.Tooltip tooltip Required (not null) Gtk.TreePath path a GtkTreePath or NULL Gtk.TreeViewColumn column a GtkTreeViewColumn or NULL Gtk.CellRenderer cell a GtkCellRenderer or NULL Returns: none	Gtk.TreeView
	set_tooltip_column (Number *column) : none If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have GtkTreeView* handle these automatically for you. If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have GtkTreeView handle these automatically for you. column should be set to the column in tree_view's model containing the tooltip texts, or -1 to disable this feature. When enabled, GtkWidget::has-tooltip will be set to TRUE and Note that the signal handler sets the text with gtk_tooltip_set_markup(), so &, <, etc have to be escaped in the text. Parameters: Number column Required (not null) Returns: none	Gtk.TreeView
	set_tooltip_markup (String *markup) : none Sets markup* as the contents of the tooltip, which is marked up with the Pango text markup language. Sets markup as the contents of the tooltip, which is marked up with the Pango text markup language. This function will take care of setting GtkWidget:has-tooltip to TRUE and of the default handler for the GtkWidget::query-tooltip signal. See also the GtkWidget:tooltip-markup property and gtk_tooltip_set_markup(). Parameters: String markup the contents of the tooltip for widget, or NULL Returns: none	Gtk.Widget
	set_tooltip_row (Tooltip *tooltip, TreePath path) : none Sets the tip area of tooltip* to be the area covered by the row at path. Sets the tip area of tooltip to be the area covered by the row at path. See also gtk_tree_view_set_tooltip_column() for a simpler alternative. See also gtk_tooltip_set_tip_area(). Parameters: Gtk.Tooltip tooltip Required (not null) Gtk.TreePath path Required (not null) Returns: none	Gtk.TreeView
	set_tooltip_text (String *text) : none Sets text* as the contents of the tooltip. Sets text as the contents of the tooltip. This function will take care of setting GtkWidget:has-tooltip to TRUE and of the default handler for the GtkWidget::query-tooltip signal. See also the GtkWidget:tooltip-text property and gtk_tooltip_set_text(). Parameters: String text Required (not null) Returns: none	Gtk.Widget
	set_tooltip_window (Window *custom_window) : none Replaces the default, usually yellow, window used for displaying tooltips with custom_window. Replaces the default, usually yellow, window used for displaying tooltips with custom_window. GTK+ will take care of showing and hiding custom_window* at the right moment, to behave likewise as the default tooltip window. If custom_window is NULL, the default tooltip window will be used. If the custom window should have the default theming it needs to have the name "gtk-tooltip", see gtk_widget_set_name(). Parameters: Gtk.Window custom_window a GtkWindow, or NULL Returns: none	Gtk.Widget
	set_uposition (Number x, Number y) : none Sets the position of a widget. Sets the position of a widget. The funny "u" in the name comes from the "user position" hint specified by the X Window System, and exists for legacy reasons. This function doesn't work if a widget is inside a container; it's only really useful on GtkWindow. Don't use this function to center dialogs over the main application window; most window managers will do the centering on your behalf if you call gtk_window_set_transient_for(), and it's really not possible to get the centering to work correctly in all cases from application code. But if you insist, use gtk_window_set_position() to set GTK_WIN_POS_CENTER_ON_PARENT, don't do the centering manually. Note that although x and y can be individually unset, the position is not honoured unless both x and y are set. Parameters: Number x Required (not null) Number y Required (not null) Returns: none	Gtk.Widget
	set_user_data (void* *data) : none Parameters: void data Required (not null) Returns: none	Gtk.Object
	set_usize (Number *width, Number height) : none Sets the minimum size of a widget; that is, the widget's size request will be width* by height. Sets the minimum size of a widget; that is, the widget's size request will be width by height. You can use this function to force a widget to be either larger or smaller than it is. The strange "usize" name dates from the early days of GTK+, and derives from X Window System terminology. In many cases, gtk_window_set_default_size() is a better choice for toplevel windows than this function; setting the default size will still allow users to shrink the window. Setting the usize will force them to leave the window at least as large as the usize. When dealing with window sizes, gtk_window_set_geometry_hints() can be a useful function as well. Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hardcode a size that will always be correct. Parameters: Number width Required (not null) Number height Required (not null) Returns: none	Gtk.Widget
	set_vadjustment (Adjustment *adjustment) : none Sets the GtkAdjustment* for the current vertical aspect. Sets the GtkAdjustment for the current vertical aspect. Parameters: Gtk.Adjustment adjustment The GtkAdjustment to set, or NULL Returns: none	Gtk.TreeView
	set_visible (Boolean *visible) : none Sets the visibility state of widget. Sets the visibility state of widget. Note that setting this to TRUE* doesn't mean the widget is actually viewable, see gtk_widget_get_visible(). This function simply calls gtk_widget_show() or gtk_widget_hide() but is nicer to use when the visibility of the widget depends on some condition. Parameters: Boolean visible Required (not null) Returns: none	Gtk.Widget
	set_window (Window *window) : none Sets a widget's window. Sets a widget's window. This function should only be used in a widget's GtkWidget::realize() implementation. The window* passed is usually either new window created with gdk_window_new(), or the window of its parent widget as returned by gtk_widget_get_parent_window(). Widgets must indicate whether they will create their own GdkWindow by calling gtk_widget_set_has_window(). This is usually done in the widget's init() function. Parameters: Gdk.Window window Required (not null) Returns: none	Gtk.Widget
	shape_combine_mask (Bitmap *shape_mask, Number offset_x, Number offset_y) : none Sets a shape for this widget's GDK window. Sets a shape for this widget's GDK window. This allows for transparent windows etc., see gdk_window_shape_combine_mask() for more information. Parameters: Gdk.Bitmap shape_mask* shape to be added, or NULL to remove an existing shape Number offset_x Required (not null) Number offset_y Required (not null) Returns: none	Gtk.Widget
	show () : none Flags a widget to be displayed. Flags a widget to be displayed. Any widget that isn't shown will not appear on the screen. If you want to show all the widgets in a container, it's easier to call gtk_widget_show_all() on the container, instead of individually showing the widgets. Remember that you have to show the containers containing a widget, in addition to the widget itself, before it will appear onscreen. When a toplevel container is shown, it is immediately realized and mapped; other shown widgets are realized and mapped when their toplevel container is realized and mapped. Returns: none	Gtk.Widget
	show_all () : none Recursively shows a widget, and any child widgets (if the widget is a container). Recursively shows a widget, and any child widgets (if the widget is a container). Returns: none	Gtk.Widget
	show_now () : none Shows a widget. Shows a widget. If the widget is an unmapped toplevel widget (i.e. a GtkWindow that has not yet been shown), enter the main loop and wait for the window to actually be mapped. Be careful; because the main loop is running, anything can happen during this function. Returns: none	Gtk.Widget
	sink () : none Returns: none	Gtk.Object
	size_allocate (Rectangle *allocation) : none This function is only used by GtkContainer* subclasses, to assign a size and position to their child widgets. This function is only used by GtkContainer subclasses, to assign a size and position to their child widgets. Parameters: Gdk.Rectangle allocation Required (not null) Returns: none	Gtk.Widget
	size_request (Requisition *requisition) : none This function is typically used when implementing a GtkContainer* subclass. This function is typically used when implementing a GtkContainer subclass. Obtains the preferred size of a widget. The container uses this information to arrange its child widgets and decide what size allocations to give them with gtk_widget_size_allocate(). You can also call this function from an application, with some caveats. Most notably, getting a size request requires the widget to be associated with a screen, because font information may be needed. Multihead-aware applications should keep this in mind. Also remember that the size request is not necessarily the size a widget will actually be allocated. See also gtk_widget_get_child_requisition(). Parameters: Gtk.Requisition requisition Required (not null) Returns: none	Gtk.Widget
	style_attach () : none This function attaches the widget's GtkStyle to the widget's GdkWindow. This function attaches the widget's GtkStyle to the widget's GdkWindow. It is a replacement for widget->style = gtk_style_attach (widget->style, widget->window); and should only ever be called in a derived widget's "realize" implementation which does not chain up to its parent class' "realize" implementation, because one of the parent classes (finally GtkWidget) would attach the style itself. Returns: none	Gtk.Widget
	style_get_property (String *property_name, Value value) : none Gets the value of a style property of widget. Gets the value of a style property of widget. Parameters: String property_name* Required (not null) GObject.Value value Required (not null) Returns: none	Gtk.Widget
	thaw_child_notify () : none Reverts the effect of a previous call to gtk_widget_freeze_child_notify(). Reverts the effect of a previous call to gtk_widget_freeze_child_notify(). This causes all queued GtkWidget::child-notify signals on widget to be emitted. Returns: none	Gtk.Widget
	translate_coordinates (Widget *dest_widget, Number src_x, Number src_y, Object out_values) : Boolean Translate coordinates relative to src_widget's allocation to coordinates relative to dest_widget's allocations. Translate coordinates relative to src_widget's allocation to coordinates relative to dest_widget's allocations. In order to perform this operation, both widgets must be realized, and must share a common toplevel. was no common ancestor. In this case, nothing is stored in dest_x and *dest_y. Otherwise TRUE. Parameters: Gtk.Widget dest_widget Required (not null) Number src_x Required (not null) Number src_y Required (not null) Object out_values Number dest_x Number dest_y Returns: Boolean	Gtk.Widget

	delete_event (Widget *self, Event event) : Boolean The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The default handler for this signal destroys the window. Connecting gtk_widget_hide_on_delete() to this signal will cause the window to be hidden instead, so that it can later be shown again without reconstructing it. FALSE* to propagate the event further. Parameters: Gtk.Widget self Gdk.Event event Returns: {Boolean}	Gtk.Widget
	destroy (Object *self) : none Parameters: Gtk.Object self* Returns: {none}	Gtk.Object
	destroy_event (Widget *self, Event event) : Boolean The ::destroy-event signal is emitted when a GdkWindow* is destroyed. The ::destroy-event signal is emitted when a GdkWindow is destroyed. You rarely get this signal, because most widgets disconnect themselves from their window before they destroy it, so no widget owns the window at destroy time. To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows. FALSE to propagate the event further. Parameters: Gtk.Widget self Gdk.Event event Returns: {Boolean}	Gtk.Widget

	drag_begin (Widget *self, DragContext drag_context) : none The ::drag-begin signal is emitted on the drag source when a drag is started. The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with gtk_drag_source_set_icon(). Note that some widgets set up a drag icon in the default handler of this signal, so you may have to use g_signal_connect_after() to override what the default handler did. Parameters: Gtk.Widget self* Gdk.DragContext drag_context Returns: {none}	Gtk.Widget
	drag_data_delete (Widget *self, DragContext drag_context) : none The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE* is successfully completed. The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE is successfully completed. The signal handler is responsible for deleting the data that has been dropped. What "delete" means depends on the context of the drag operation. Parameters: Gtk.Widget self Gdk.DragContext drag_context Returns: {none}	Gtk.Widget
	drag_data_get (Widget *self, DragContext drag_context, SelectionData data, Number info, Number time) : none The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. It is the responsibility of the signal handler to fill data* with the data in the format which is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text(). Parameters: Gtk.Widget self Gdk.DragContext drag_context Gtk.SelectionData data Number info Number time Returns: {none}	Gtk.Widget
	drag_data_received (Widget *self, DragContext drag_context, Number x, Number y, SelectionData data, Number info, Number time) : none The ::drag-data-received signal is emitted on the drop site when the dragged data has been received. The ::drag-data-received signal is emitted on the drop site when the dragged data has been received. If the data was received in order to determine whether the drop will be accepted, the handler is expected to call gdk_drag_status() and not finish the drag. If the data was received in response to a GtkWidget::drag-drop signal (and this is the last target to be received), the handler for this signal is expected to process the received data and then call gtk_drag_finish(), setting the success* parameter depending on whether the data was processed successfully. The handler may inspect and modify drag_context->action before calling gtk_drag_finish(), e.g. to implement GDK_ACTION_ASK as shown in the following example: \|[ void drag_data_received (GtkWidget widget, GdkDragContext drag_context, gint x, gint y, GtkSelectionData data, guint info, guint time) { if ((data->length >= 0) && (data->format == 8)) { if (drag_context->action == GDK_ACTION_ASK) { GtkWidget dialog; gint response; dialog = gtk_message_dialog_new (NULL, GTK_DIALOG_MODAL \| GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_INFO, GTK_BUTTONS_YES_NO, "Move the data ?\n"); response = gtk_dialog_run (GTK_DIALOG (dialog)); gtk_widget_destroy (dialog); if (response == GTK_RESPONSE_YES) drag_context->action = GDK_ACTION_MOVE; else drag_context->action = GDK_ACTION_COPY; } gtk_drag_finish (drag_context, TRUE, FALSE, time); return; } gtk_drag_finish (drag_context, FALSE, FALSE, time); } ]\| Parameters: Gtk.Widget self Gdk.DragContext drag_context Number x Number y Gtk.SelectionData data Number info Number time Returns: {none}	Gtk.Widget
	drag_drop (Widget *self, DragContext drag_context, Number x, Number y, Number time) : Boolean The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE* and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler must ensure that gtk_drag_finish() is called to let the source know that the drop is done. The call to gtk_drag_finish() can be done either directly or in a GtkWidget::drag-data-received handler which gets triggered by calling gtk_drag_get_data() to receive the data for one or more of the supported targets. Parameters: Gtk.Widget self Gdk.DragContext drag_context Number x Number y Number time Returns: {Boolean}	Gtk.Widget
	drag_end (Widget *self, DragContext drag_context) : none The ::drag-end signal is emitted on the drag source when a drag is finished. The ::drag-end signal is emitted on the drag source when a drag is finished. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-begin. Parameters: Gtk.Widget self* Gdk.DragContext drag_context Returns: {none}	Gtk.Widget
	drag_failed (Widget *self, DragContext drag_context, DragResult result) : Boolean The ::drag-failed signal is emitted on the drag source when a drag has failed. The ::drag-failed signal is emitted on the drag source when a drag has failed. The signal handler may hook custom code to handle a failed DND operation based on the type of error, it returns TRUE* is the failure has been already handled (not showing the default "drag operation failed" animation), otherwise it returns FALSE. Parameters: Gtk.Widget self Gdk.DragContext drag_context Gtk.DragResult result Returns: {Boolean}	Gtk.Widget
	drag_leave (Widget *self, DragContext drag_context, Number time) : none The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-motion, e.g. undo highlighting with gtk_drag_unhighlight() Parameters: Gtk.Widget self* Gdk.DragContext drag_context Number time Returns: {none}	Gtk.Widget
	drag_motion (Widget *self, DragContext drag_context, Number x, Number y, Number time) : Boolean The drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE* and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler is responsible for providing the necessary information for displaying feedback to the user, by calling gdk_drag_status(). If the decision whether the drop will be accepted or rejected can't be made based solely on the cursor position and the type of the data, the handler may inspect the dragged data by calling gtk_drag_get_data() and defer the gdk_drag_status() call to the GtkWidget::drag-data-received handler. Note that you cannot not pass GTK_DEST_DEFAULT_DROP, GTK_DEST_DEFAULT_MOTION or GTK_DEST_DEFAULT_ALL to gtk_drag_dest_set() when using the drag-motion signal that way. Also note that there is no drag-enter signal. The drag receiver has to keep track of whether he has received any drag-motion signals since the last GtkWidget::drag-leave and if not, treat the drag-motion signal as an "enter" signal. Upon an "enter", the handler will typically highlight the drop site with gtk_drag_highlight(). \|[ static void drag_motion (GtkWidget widget, GdkDragContext context, gint x, gint y, guint time) { GdkAtom target; PrivateData private_data = GET_PRIVATE_DATA (widget); if (!private_data->drag_highlight) { private_data->drag_highlight = 1; gtk_drag_highlight (widget); } target = gtk_drag_dest_find_target (widget, context, NULL); if (target == GDK_NONE) gdk_drag_status (context, 0, time); else { private_data->pending_status = context->suggested_action; gtk_drag_get_data (widget, context, target, time); } return TRUE; } static void drag_data_received (GtkWidget widget, GdkDragContext context, gint x, gint y, GtkSelectionData selection_data, guint info, guint time) { PrivateData private_data = GET_PRIVATE_DATA (widget); if (private_data->suggested_action) { private_data->suggested_action = 0; / We are getting this data due to a request in drag_motion, * rather than due to a request in drag_drop, so we are just * supposed to call gdk_drag_status (), not actually paste in * the data. / str = gtk_selection_data_get_text (selection_data); if (!data_is_acceptable (str)) gdk_drag_status (context, 0, time); else gdk_drag_status (context, private_data->suggested_action, time); } else { / accept the drop / } } ]\| Parameters: Gtk.Widget self* Gdk.DragContext drag_context Number x Number y Number time Returns: {Boolean}	Gtk.Widget
