Hierarchy

  • TreeRowReference

Index

Constructors

  • Creates a row reference based on path. This reference will keep pointing to the node pointed to by path, so long as it exists. It listens to all signals emitted by model, and updates its path appropriately. If path isn't a valid path in model, then %NULL is returned.

    Parameters

    Returns Gtk.TreeRowReference

Properties

name: string

Methods

  • free(): void
  • valid(): boolean
  • Lets a set of row reference created by gtk_tree_row_reference_new_proxy() know that the model emitted the "row_deleted" signal.

    Parameters

    Returns void

  • Lets a set of row reference created by gtk_tree_row_reference_new_proxy() know that the model emitted the "row_inserted" signal.

    Parameters

    Returns void

  • Creates a row reference based on path. This reference will keep pointing to the node pointed to by path, so long as it exists. It listens to all signals emitted by model, and updates its path appropriately. If path isn't a valid path in model, then %NULL is returned.

    Parameters

    Returns Gtk.TreeRowReference

  • You do not need to use this function. Creates a row reference based on path. This reference will keep pointing to the node pointed to by path, so long as it exists. If path isn't a valid path in model, then %NULL is returned. However, unlike references created with gtk_tree_row_reference_new(), it does not listen to the model for changes. The creator of the row reference must do this explicitly using gtk_tree_row_reference_inserted(), gtk_tree_row_reference_deleted(), gtk_tree_row_reference_reordered().

    These functions must be called exactly once per proxy when the corresponding signal on the model is emitted. This single call updates all row references for that proxy. Since built-in GTK+ objects like #GtkTreeView already use this mechanism internally, using them as the proxy object will produce unpredictable results. Further more, passing the same object as model and proxy doesn't work for reasons of internal implementation.

    This type of row reference is primarily meant by structures that need to carefully monitor exactly when a row reference updates itself, and is not generally needed by most applications.

    Parameters

    Returns Gtk.TreeRowReference

  • Lets a set of row reference created by gtk_tree_row_reference_new_proxy() know that the model emitted the "rows_reordered" signal.

    Parameters

    • proxy: GObject.Object

      A #GObject

    • path: Gtk.TreePath

      The parent path of the reordered signal

    • iter: Gtk.TreeIter

      The iter pointing to the parent of the reordered

    • new_order: number

      The new order of rows

    Returns void
