Signal

GtkToolItem::create-menu-proxy

Declaration 

gboolean
create_menu_proxy (
  GtkToolItem* self,
  gpointer user_data
)

Description [src]

This signal is emitted when the toolbar needs information from tool_item about whether the item should appear in the toolbar overflow menu. In response the tool item should either

  • call gtk_tool_item_set_proxy_menu_item() with a NULL pointer and return TRUE to indicate that the item should not appear in the overflow menu

  • call gtk_tool_item_set_proxy_menu_item() with a new menu item and return TRUE, or

  • return FALSE to indicate that the signal was not handled by the item. This means that the item will not appear in the overflow menu unless a later handler installs a menu item.

The toolbar may cache the result of this signal. When the tool item changes how it will respond to this signal it must call gtk_tool_item_rebuild_menu() to invalidate the cache and ensure that the toolbar rebuilds its overflow menu.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

Return value

Type: gboolean

TRUE if the signal was handled, FALSE if not.
