- * gtk_widget_get_toplevel:
- * @widget: a #GtkWidget
- *
- * This function returns the topmost widget in the container hierarchy
- * @widget is a part of. If @widget has no parent widgets, it will be
- * returned as the topmost widget. No reference will be added to the
- * returned widget; it should not be unreferenced.
- *
- * Note the difference in behavior vs. gtk_widget_get_ancestor();
- * `gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW)`
- * would return
- * %NULL if @widget wasn’t inside a toplevel window, and if the
- * window was inside a #GtkWindow-derived widget which was in turn
- * inside the toplevel #GtkWindow.
- *
- * To reliably find the toplevel #GtkWindow, use
- * gtk_widget_get_toplevel() and call GTK_IS_WINDOW()
- * on the result. For instance, to get the title of a widget's toplevel
- * window, one might use:
- * |[<!-- language="C" -->
- * static const char *
- * get_widget_toplevel_title (GtkWidget *widget)
- * {
- *   GtkWidget *toplevel = gtk_widget_get_toplevel (widget);
- *   if (GTK_IS_WINDOW (toplevel))
- *     {
- *       return gtk_window_get_title (GTK_WINDOW (toplevel));
- *     }
- *
- *   return NULL;
- * }
- * ]|
- *
- * Returns: (transfer none): the topmost ancestor of @widget, or @widget itself
- *    if there’s no ancestor.
