Gtk.ToolItem.prototype.get_proxy_menu_item

function get_proxy_menu_item(menu_item_id:String):Gtk.Widget {
    // Gjs wrapper for gtk_tool_item_get_proxy_menu_item()
}

If menu_item_id matches the string passed to Gtk.set_proxy_menu_item return the corresponding Gtk.MenuItem.

Custom subclasses of Gtk.ToolItem should use this function to update their menu item when the Gtk.ToolItem changes. That the menu_item_id<!-- -->s must match ensures that a Gtk.ToolItem will not inadvertently change a menu item that they did not create.
