	new Gdk.Drawable (Object *properties) Create a new Gdk.Drawable Create a new Gdk.Drawable Parameters: Object properties*
	copy_to_image (Image *image, Number src_x, Number src_y, Number dest_x, Number dest_y, Number width, Number height) : Gdk.Image Copies a portion of drawable* into the client side image structure and copies into that. Copies a portion of drawable into the client side image structure and copies into that. See gdk_drawable_get_image() for further details. of drawable Parameters: Gdk.Image image a GdkDrawable, or NULL if a new image should be created. Number src_x Required (not null) Number src_y Required (not null) Number dest_x Required (not null) Number dest_y Required (not null) Number width Required (not null) Number height Required (not null) Returns: Gdk.Image	Gdk.Drawable
	get_clip_region () : Gdk.Region Computes the region of a drawable that potentially can be written to by drawing primitives. Computes the region of a drawable that potentially can be written to by drawing primitives. This region will not take into account the clip region for the GC, and may also not take into account other factors such as if the window is obscured by other windows, but no area outside of this region will be affected by drawing primitives. when you are done. Returns: Gdk.Region	Gdk.Drawable
	get_colormap () : Gdk.Colormap Gets the colormap for drawable, if one is set; returns NULL otherwise. Gets the colormap for drawable, if one is set; returns NULL otherwise. Returns: Gdk.Colormap	Gdk.Drawable
	get_data (String *key) : void Equivalent to g_object_get_data(); the GObject variant should be used instead. Equivalent to g_object_get_data(); the GObject variant should be used instead. Parameters: String key Required (not null) Returns: void*	Gdk.Drawable
	get_depth () : Number Obtains the bit depth of the drawable, that is, the number of bits that make up a pixel in the drawable's visual. Obtains the bit depth of the drawable, that is, the number of bits that make up a pixel in the drawable's visual. Examples are 8 bits per pixel, 24 bits per pixel, etc. Returns: Number	Gdk.Drawable
	get_display () : Gdk.Display Gets the GdkDisplay associated with a GdkDrawable. Gets the GdkDisplay associated with a GdkDrawable. Returns: Gdk.Display	Gdk.Drawable
	get_image (Number x, Number y, Number *width, Number height) : Gdk.Image A GdkImage* stores client-side image data (pixels). A GdkImage stores client-side image data (pixels). In contrast, GdkPixmap and GdkWindow are server-side objects. gdk_drawable_get_image() obtains the pixels from a server-side drawable as a client-side GdkImage. The format of a GdkImage depends on the GdkVisual of the current display, which makes manipulating GdkImage extremely difficult; therefore, in most cases you should use gdk_pixbuf_get_from_drawable() instead of this lower-level function. A GdkPixbuf contains image data in a canonicalized RGB format, rather than a display-dependent format. Of course, there's a convenience vs. speed tradeoff here, so you'll want to think about what makes sense for your application. obtain as an image. You would usually copy image data to the client side if you intend to examine the values of individual pixels, for example to darken an image or add a red tint. It would be prohibitively slow to make a round-trip request to the windowing system for each pixel, so instead you get all of them at once, modify them, then copy them all back at once. If the X server or other windowing system backend is on the local machine, this function may use shared memory to avoid copying the image data. If the source drawable is a GdkWindow and partially offscreen or obscured, then the obscured portions of the returned image will contain undefined data. Parameters: Number x Required (not null) Number y Required (not null) Number width Required (not null) Number height Required (not null) Returns: Gdk.Image	Gdk.Drawable
	get_screen () : Gdk.Screen Gets the GdkScreen associated with a GdkDrawable. Gets the GdkScreen associated with a GdkDrawable. Returns: Gdk.Screen	Gdk.Drawable
	get_size () : Object Fills *width and *height with the size of drawable. Fills *width and *height with the size of drawable. On the X11 platform, if drawable is a GdkWindow, the returned size is the size reported in the most-recently-processed configure event, rather than the current size on the X server. Returns: width: Number height: Number	Gdk.Drawable
	get_visible_region () : Gdk.Region Computes the region of a drawable that is potentially visible. Computes the region of a drawable that is potentially visible. This does not necessarily take into account if the window is obscured by other windows, but no area outside of this region is visible. when you are done. Returns: Gdk.Region	Gdk.Drawable
	get_visual () : Gdk.Visual Gets the GdkVisual describing the pixel format of drawable. Gets the GdkVisual describing the pixel format of drawable. Returns: Gdk.Visual	Gdk.Drawable
	set_colormap (Colormap *colormap) : none Sets the colormap associated with drawable. Sets the colormap associated with drawable. Normally this will happen automatically when the drawable is created; you only need to use this function if the drawable-creating function did not have a way to determine the colormap, and you then use drawable operations that require a colormap. The colormap for all drawables and graphics contexts you intend to use together should match. i.e. when using a GdkGC* to draw to a drawable, or copying one drawable to another, the colormaps should match. Parameters: Gdk.Colormap colormap Required (not null) Returns: none	Gdk.Drawable
	set_data (String *key, void *data, Function destroy_func) : none This function is equivalent to g_object_set_data(), the GObject* variant should be used instead. This function is equivalent to g_object_set_data(), the GObject variant should be used instead. Parameters: String key Required (not null) void* data Required (not null) Function (void* *data) : none function to free data, or NULL* Returns: none	Gdk.Drawable
