GtkMenu::set_title

set_title() sets the window title for a menu that has been detached from its parent through either a GtkTearoffMenuItem widget or the set_tearoff_state() method. As with all window titles, the text will be truncated to fit the area available.

Note that the title needs to be set prior to the menu's becoming torn off.

If the title is not set, the torn off menu will display in its title bar either the text in the parent GtkMenuItem's label or, where there is none, the full file path.
