public class Menu : MenuShell, Implementor, Buildable

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 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.

  // 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.

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;
