#[repr(transparent)]pub struct Menu { /* private fields */ }Expand description
A Menu is a MenuShell that implements a drop down menu
consisting of a list of MenuItem objects which can be navigated
and activated by the user to perform application functions.
A Menu is most commonly dropped down by activating a
MenuItem in a MenuBar or popped up by activating a
MenuItem in another Menu.
A Menu can also be popped up by activating a ComboBox.
Other composite widgets such as the Notebook can pop up a
Menu as well.
Applications can display a Menu as a popup menu by calling the
gtk_menu_popup() function. The example below shows how an application
can pop up a menu when the 3rd mouse button is pressed.
Connecting the popup signal handler.
⚠️ The following code is in C ⚠️
  // connect our handler which will popup the menu
  g_signal_connect_swapped (window, "button_press_event",
G_CALLBACK (my_popup_handler), menu);Signal handler which displays a popup menu.
⚠️ The following code is in C ⚠️
static gint
my_popup_handler (GtkWidget *widget, GdkEvent *event)
{
  GtkMenu *menu;
  GdkEventButton *event_button;
  g_return_val_if_fail (widget != NULL, FALSE);
  g_return_val_if_fail (GTK_IS_MENU (widget), FALSE);
  g_return_val_if_fail (event != NULL, FALSE);
  // The "widget" is the menu that was supplied when
  // g_signal_connect_swapped() was called.
  menu = GTK_MENU (widget);
  if (event->type == GDK_BUTTON_PRESS)
    {
      event_button = (GdkEventButton *) event;
      if (event_button->button == GDK_BUTTON_SECONDARY)
        {
          gtk_menu_popup (menu, NULL, NULL, NULL, NULL,
                          event_button->button, event_button->time);
          return TRUE;
        }
    }
  return FALSE;

Implementations
sourceimpl Menu
 
impl Menu
pub const NONE: Option<&'static Menu> = None
sourcepub fn from_model(model: &impl IsA<MenuModel>) -> Menu
 
pub fn from_model(model: &impl IsA<MenuModel>) -> Menu
Creates a Menu and populates it with menu items and
submenus according to model.
The created menu items are connected to actions found in the
ApplicationWindow to which the menu belongs - typically
by means of being attached to a widget (see gtk_menu_attach_to_widget())
that is contained within the GtkApplicationWindows widget hierarchy.
Actions can also be added using WidgetExt::insert_action_group() on the menu’s
attach widget or on any of its parent widgets.
model
Returns
a new Menu
sourcepub fn builder() -> MenuBuilder
 
pub fn builder() -> MenuBuilder
Creates a new builder-pattern struct instance to construct Menu objects.
This method returns an instance of MenuBuilder which can be used to create Menu objects.
