Appends a new row to tree_store. If parent is non-null, then it will append the new row after the last child of parent, otherwise it will append a row to the top level. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.tree_store.TreeStore.set or gtk.tree_store.TreeStore.setValue.
Removes all rows from tree_store
Creates a new row at position. If parent is non-null, then the row will be made a child of parent. Otherwise, the row will be created at the toplevel. If position is -1 or is larger than the number of rows at that level, then the new row will be inserted to the end of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.tree_store.TreeStore.set or gtk.tree_store.TreeStore.setValue.
Inserts a new row after sibling. If sibling is null, then the row will be prepended to parent ’s children. If parent and sibling are null, then the row will be prepended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional.
Inserts a new row before sibling. If sibling is null, then the row will be appended to parent ’s children. If parent and sibling are null, then the row will be appended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling. When sibling is set, parent is optional.
A variant of gtk.tree_store.TreeStore.insertWithValues which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language bindings.
Returns true if iter is an ancestor of descendant. That is, iter is the parent (or grandparent or great-grandparent) of descendant.
Returns the depth of iter. This will be 0 for anything on the root level, 1 for anything down a level, etc.
WARNING: This function is slow. Only use it for debugging and/or testing purposes.
Moves iter in tree_store to the position after position. iter and position should be in the same level. Note that this function only works with unsorted stores. If position is null, iter will be moved to the start of the level.
Moves iter in tree_store to the position before position. iter and position should be in the same level. Note that this function only works with unsorted stores. If position is null, iter will be moved to the end of the level.
Prepends a new row to tree_store. If parent is non-null, then it will prepend the new row before the first child of parent, otherwise it will prepend a row to the top level. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.tree_store.TreeStore.set or gtk.tree_store.TreeStore.setValue.
Removes iter from tree_store. After being removed, iter is set to the next valid row at that level, or invalidated if it previously pointed to the last one.
Returns this, for use in with statements.
A variant of gtk.tree_store.TreeStore.setValist which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language bindings or in case the number of columns to change is not known until run-time.
This function is meant primarily for #GObjects that inherit from #GtkTreeStore, and should only be used when constructing a new #GtkTreeStore. It will not function after a row has been added, or a method on the #GtkTreeModel interface is called.
Sets the data in the cell specified by iter and column. The type of value must be convertible to the type of the column.
Swaps a and b in the same level of tree_store. Note that this function only works with unsorted stores.

Asks the #GtkTreeDragDest to insert a row before the path dest, deriving the contents of the row from selection_data. If dest is outside the tree so that inserting before it is impossible, false will be returned. Also, false may be returned if the new row is not created for some model-specific reason. Should robustly handle a dest no longer found in the model!
Determines whether a drop is possible before the given dest_path, at the same depth as dest_path. i.e., can we drop the data in selection_data at that location. dest_path does not have to exist; the return value will almost certainly be false if the parent of dest_path doesn’t exist, though.

Returns true if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.
Sets the default comparison function used when sorting to be sort_func. If the current sort column id of sortable is gtk.types.TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function.
Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a #GtkTreeSortable::sort-column-changed signal. sort_column_id may either be a regular column id, or one of the following special values:

Creates a binding between source_property on source and target_property on target.
Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectWrap.refSink.
Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
Gets a named field from the objects table of associations (see gobject.object.ObjectWrap.setData).
Gets a property of an object.
This function gets back user data pointers stored via gobject.object.ObjectWrap.setQdata.
Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Checks whether object has a floating[floating-ref] reference.
Emits a "notify" signal for the property property_name on object.
Emits a "notify" signal for the property specified by pspec on object.
Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Sets a property on an object.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via gobject.object.ObjectWrap.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
Reverts the effect of a previous call to gobject.object.ObjectWrap.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectWrap.ref_ and gobject.object.ObjectWrap.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

The #GtkTreeStore object is a list model for use with a #GtkTreeView widget. It implements the #GtkTreeModel interface, and consequentially, can use all of the methods available there. It also implements the #GtkTreeSortable interface so it can be sorted by the view. Finally, it also implements the tree [drag and drop][gtk3-GtkTreeView-drag-and-drop] interfaces.
GtkTreeStore as GtkBuildable
The GtkTreeStore implementation of the #GtkBuildable interface allows to specify the model columns with a <columns> element that may contain multiple <column> elements, each specifying one model column. The “type” attribute specifies the data type for the column.
An example of a UI Definition fragment for a tree store:
