To be more specific, models may ignore this call as it exists primarily for performance reasons. This function is primarily meant as a way for views to let caching model know when nodes are being displayed (and hence, whether or not to cache that node.) For example, a file-system based model would not want to keep the entire file-hierarchy in memory, just the sections that are currently being displayed by every current view.

Event		Defined By
	row_changed (TreeModel *self, TreePath path, TreeIter iter) : none This signal is emitted when a row in the model has changed. This signal is emitted when a row in the model has changed. Parameters: Gtk.TreeModel self* Gtk.TreePath path Gtk.TreeIter iter Returns: {none}	Gtk.TreeModel
	row_deleted (TreeModel *self, TreePath path) : none This signal is emitted when a row has been deleted. This signal is emitted when a row has been deleted. Note that no iterator is passed to the signal handler, since the row is already deleted. Implementations of GtkTreeModel must emit row-deleted before removing the node from its internal data structures. This is because models and views which access and monitor this model might have references on the node which need to be released in the row-deleted handler. Parameters: Gtk.TreeModel self* Gtk.TreePath path Returns: {none}	Gtk.TreeModel
	row_has_child_toggled (TreeModel *self, TreePath path, TreeIter iter) : none This signal is emitted when a row has gotten the first child row or lost its last child row. This signal is emitted when a row has gotten the first child row or lost its last child row. Parameters: Gtk.TreeModel self* Gtk.TreePath path Gtk.TreeIter iter Returns: {none}	Gtk.TreeModel
	row_inserted (TreeModel *self, TreePath path, TreeIter iter) : none This signal is emitted when a new row has been inserted in the model. This signal is emitted when a new row has been inserted in the model. Note that the row may still be empty at this point, since it is a common pattern to first insert an empty row, and then fill it with the desired values. Parameters: Gtk.TreeModel self* Gtk.TreePath path Gtk.TreeIter iter Returns: {none}	Gtk.TreeModel
	rows_reordered (TreeModel *self, TreePath path, TreeIter iter, void *new_order) : none This signal is emitted when the children of a node in the GtkTreeModel* have been reordered. This signal is emitted when the children of a node in the GtkTreeModel have been reordered. Note that this signal is not emitted when rows are reordered by DND, since this is implemented by removing and then reinserting the row. Parameters: Gtk.TreeModel self Gtk.TreePath path Gtk.TreeIter iter void* new_order Returns: {none}	Gtk.TreeModel
	sort_column_changed (TreeSortable *self) : none The ::sort-column-changed signal is emitted when the sort column or sort order of sortable* is changed. The ::sort-column-changed signal is emitted when the sort column or sort order of sortable is changed. The signal is emitted before the contents of sortable are resorted. Parameters: Gtk.TreeSortable self Returns: {none}	Gtk.TreeSortable
