Methods / Constructors
Method / Constructor		Defined By
	foreach (Function *func, void *user_data) : none Calls func on each node in model in a depth-first fashion. Calls func on each node in model in a depth-first fashion. If func* returns TRUE, then the tree ceases to be walked, and gtk_tree_model_foreach() returns. Parameters: Function (TreeModel *model, TreePath path, TreeIter iter, void *data) : none Required (not null) void user_data Required (not null) Returns: none	Gtk.TreeModel
	get_column_type (Number *index_) : Number Returns the type of the column. Returns the type of the column. Parameters: Number index_* Required (not null) Returns: Number	Gtk.TreeModel
	get_flags () : Gtk.TreeModelFlags Returns a set of flags supported by this interface. Returns a set of flags supported by this interface. The flags are a bitwise combination of GtkTreeModelFlags. The flags supported should not change during the lifecycle of the tree_model. Returns: Gtk.TreeModelFlags	Gtk.TreeModel
	get_iter (TreeIter *iter, TreePath path) : Boolean Sets iter* to a valid iterator pointing to path. Sets iter to a valid iterator pointing to path. Parameters: Gtk.TreeIter iter Required (not null) Gtk.TreePath path Required (not null) Returns: Boolean	Gtk.TreeModel
	get_iter_first (TreeIter *iter) : Boolean Initializes iter* with the first iterator in the tree (the one at the path "0") and returns TRUE. Initializes iter with the first iterator in the tree (the one at the path "0") and returns TRUE. Returns FALSE if the tree is empty. Parameters: Gtk.TreeIter iter Required (not null) Returns: Boolean	Gtk.TreeModel
	get_iter_from_string (TreeIter *iter, String path_string) : Boolean Sets iter* to a valid iterator pointing to path_string, if it exists. Sets iter to a valid iterator pointing to path_string, if it exists. Otherwise, iter is left invalid and FALSE is returned. Parameters: Gtk.TreeIter iter Required (not null) String path_string Required (not null) Returns: Boolean	Gtk.TreeModel
	get_n_columns () : Number Returns the number of columns supported by tree_model. Returns the number of columns supported by tree_model. Returns: Number	Gtk.TreeModel
	get_path (TreeIter *iter) : Gtk.TreePath Returns a newly-created GtkTreePath* referenced by iter. Returns a newly-created GtkTreePath referenced by iter. This path should be freed with gtk_tree_path_free(). Parameters: Gtk.TreeIter iter Required (not null) Returns: Gtk.TreePath	Gtk.TreeModel
	get_string_from_iter (TreeIter *iter) : String Generates a string representation of the iter. Generates a string representation of the iter. This string is a ':' separated list of numbers. For example, "4:10:0:3" would be an acceptable return value for this string. Parameters: Gtk.TreeIter iter* Required (not null) Returns: String	Gtk.TreeModel
	get_value (TreeIter *iter, Number column, Value value) : none Initializes and sets value* to that at column. Initializes and sets value to that at column. When done with value, g_value_unset() needs to be called to free any allocated memory. Parameters: Gtk.TreeIter iter Required (not null) Number column Required (not null) GObject.Value value Required (not null) An empty GValue to set. Returns: none	Gtk.TreeModel
	iter_children (TreeIter *iter, TreeIter parent) : Boolean Sets iter* to point to the first child of parent. Sets iter to point to the first child of parent. If parent has no children, FALSE is returned and iter is set to be invalid. parent will remain a valid node after this function has been called. If parent is NULL returns the first node, equivalent to gtk_tree_model_get_iter_first (tree_model, iter); Parameters: Gtk.TreeIter iter Required (not null) Gtk.TreeIter parent The GtkTreeIter, or NULL Returns: Boolean	Gtk.TreeModel
	iter_has_child (TreeIter *iter) : Boolean Returns TRUE* if iter has children, FALSE otherwise. Returns TRUE if iter has children, FALSE otherwise. Parameters: Gtk.TreeIter iter Required (not null) Returns: Boolean	Gtk.TreeModel
	iter_n_children (TreeIter *iter) : Number Returns the number of children that iter* has. Returns the number of children that iter has.

	iter_nth_child (TreeIter *iter, TreeIter parent, Number n) : Boolean Sets iter* to be the child of parent, using the given index. Sets iter to be the child of parent, using the given index. The first index is 0. If n is too big, or parent has no children, iter is set to an invalid iterator and FALSE is returned. parent will remain a valid node after this function has been called. As a special case, if parent is NULL, then the nth root node is set. Parameters: Gtk.TreeIter iter Required (not null) Gtk.TreeIter parent The GtkTreeIter to get the child from, or NULL. Number n Required (not null) Returns: Boolean	Gtk.TreeModel
	iter_parent (TreeIter *iter, TreeIter child) : Boolean Sets iter* to be the parent of child. Sets iter to be the parent of child. If child is at the toplevel, and doesn't have a parent, then iter is set to an invalid iterator and FALSE is returned. child will remain a valid node after this function has been called. Parameters: Gtk.TreeIter iter Required (not null) Gtk.TreeIter child Required (not null) Returns: Boolean	Gtk.TreeModel
	ref_node (TreeIter *iter) : none Lets the tree ref the node. Lets the tree ref the node. This is an optional method for models to implement. 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. A model should be expected to be able to get an iter independent of its reffed state. Parameters: Gtk.TreeIter iter* Required (not null) Returns: none	Gtk.TreeModel
	row_changed (TreePath *path, TreeIter iter) : none Emits the "row-changed" signal on tree_model. Emits the "row-changed" signal on tree_model. Parameters: Gtk.TreePath path* Required (not null) Gtk.TreeIter iter Required (not null) Returns: none	Gtk.TreeModel
	row_deleted (TreePath *path) : none Emits the "row-deleted" signal on tree_model. Emits the "row-deleted" signal on tree_model. This should be called by models after a row has been removed. The location pointed to by path* should be the location that the row previously was at. It may not be a valid location anymore. Parameters: Gtk.TreePath path Required (not null) Returns: none	Gtk.TreeModel
	row_has_child_toggled (TreePath *path, TreeIter iter) : none Emits the "row-has-child-toggled" signal on tree_model. Emits the "row-has-child-toggled" signal on tree_model. This should be called by models after the child state of a node changes. Parameters: Gtk.TreePath path* Required (not null) Gtk.TreeIter iter Required (not null) Returns: none	Gtk.TreeModel
	row_inserted (TreePath *path, TreeIter iter) : none Emits the "row-inserted" signal on tree_model* Emits the "row-inserted" signal on tree_model Parameters: Gtk.TreePath path Required (not null) Gtk.TreeIter iter Required (not null) Returns: none	Gtk.TreeModel
	rows_reordered (TreePath *path, TreeIter iter) : Number Emits the "rows-reordered" signal on tree_model. Emits the "rows-reordered" signal on tree_model. This should be called by models when their rows have been reordered. Parameters: Gtk.TreePath path* Required (not null) reordered Gtk.TreeIter iter Required (not null) reordered, or NULL if the depth of path is 0. Returns: Number	Gtk.TreeModel
	unref_node (TreeIter *iter) : none Lets the tree unref the node. Lets the tree unref the node. This is an optional method for models to implement. To be more specific, models may ignore this call as it exists primarily for performance reasons. For more information on what this means, see gtk_tree_model_ref_node(). Please note that nodes that are deleted are not unreffed. Parameters: Gtk.TreeIter iter* Required (not null) Returns: none	Gtk.TreeModel

Events - usage syntax: this.signals.EVENTNAME.connect( Function )
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
