GtkMenuItem

GtkMenuItem as GtkBuildable

The GtkMenuItem implementation of the GtkBuildable interface supports adding a submenu by specifying “submenu” as the “type” attribute of a <child> element.

An example of UI definition fragment with submenus:

CSS nodes

GtkWidget *menu_item = gtk_menu_item_new_with_label ("Example Menu Item");

GtkWidget *child = gtk_bin_get_child (GTK_BIN (menu_item));
gtk_label_set_markup (GTK_LABEL (child), "<i>new label</i> with <b>markup</b>");
gtk_accel_label_set_accel (GTK_ACCEL_LABEL (child), GDK_KEY_1, 0);

GtkMenuItem has a single CSS node with name menuitem. If the menuitem has a submenu, it gets another CSS node with name arrow, which has the .left or .right style class.

gtk_menu_item_new ()

GtkWidget *
gtk_menu_item_new (void);

Creates a new GtkMenuItem.

gtk_menu_item_new_with_label ()

GtkWidget *
gtk_menu_item_new_with_label (const gchar *label);

Creates a new GtkMenuItem whose child is a GtkLabel.

gtk_menu_item_new_with_mnemonic ()

GtkWidget *
gtk_menu_item_new_with_mnemonic (const gchar *label);

Creates a new GtkMenuItem containing a label.

The label will be created using gtk_label_new_with_mnemonic(), so underscores in label indicate the mnemonic for the menu item.

gtk_menu_item_set_right_justified ()

void
gtk_menu_item_set_right_justified (GtkMenuItem *menu_item,
                                   gboolean right_justified);

Sets whether the menu item appears justified at the right side of a menu bar. This was traditionally done for “Help” menu items, but is now considered a bad idea. (If the widget layout is reversed for a right-to-left language like Hebrew or Arabic, right-justified-menu-items appear at the left.)

gtk_menu_item_get_right_justified ()

gboolean
gtk_menu_item_get_right_justified (GtkMenuItem *menu_item);

Gets whether the menu item appears justified at the right side of the menu bar.

gtk_menu_item_get_label ()

const gchar *
gtk_menu_item_get_label (GtkMenuItem *menu_item);

Sets text on the menu_item label

Since: 2.16

gtk_menu_item_set_label ()

void
gtk_menu_item_set_label (GtkMenuItem *menu_item,
                         const gchar *label);

Sets text on the menu_item label

Since: 2.16

gtk_menu_item_get_use_underline ()

gboolean
gtk_menu_item_get_use_underline (GtkMenuItem *menu_item);

Checks if an underline in the text indicates the next character should be used for the mnemonic accelerator key.

Since: 2.16

gtk_menu_item_set_use_underline ()

void
gtk_menu_item_set_use_underline (GtkMenuItem *menu_item,
                                 gboolean setting);

If true, an underline in the text indicates the next character should be used for the mnemonic accelerator key.

Since: 2.16

gtk_menu_item_set_submenu ()

void
gtk_menu_item_set_submenu (GtkMenuItem *menu_item,
                           GtkWidget *submenu);

Sets or replaces the menu item’s submenu, or removes it when a NULL submenu is passed.

gtk_menu_item_get_submenu ()

GtkWidget *
gtk_menu_item_get_submenu (GtkMenuItem *menu_item);

Gets the submenu underneath this menu item, if any. See gtk_menu_item_set_submenu().

gtk_menu_item_set_accel_path ()

void
gtk_menu_item_set_accel_path (GtkMenuItem *menu_item,
                              const gchar *accel_path);

Set the accelerator path on menu_item , through which runtime changes of the menu item’s accelerator caused by the user can be identified and saved to persistent storage (see gtk_accel_map_save() on this). To set up a default accelerator for this menu item, call gtk_accel_map_add_entry() with the same accel_path . See also gtk_accel_map_add_entry() on the specifics of accelerator paths, and gtk_menu_set_accel_path() for a more convenient variant of this function.

This function is basically a convenience wrapper that handles calling gtk_widget_set_accel_path() with the appropriate accelerator group for the menu item.

Note that you do need to set an accelerator on the parent menu with gtk_menu_set_accel_group() for this to work.

Note that accel_path string will be stored in a GQuark. Therefore, if you pass a static string, you can save some memory by interning it first with g_intern_static_string().

gtk_menu_item_get_accel_path ()

const gchar *
gtk_menu_item_get_accel_path (GtkMenuItem *menu_item);

Retrieve the accelerator path that was previously set on menu_item .

See gtk_menu_item_set_accel_path() for details.

Since: 2.14

gtk_menu_item_select ()

void
gtk_menu_item_select (GtkMenuItem *menu_item);

Emits the “deselect” signal on the given item.

gtk_menu_item_activate ()

void
gtk_menu_item_activate (GtkMenuItem *menu_item);

Emits the “activate” signal on the given item

gtk_menu_item_toggle_size_request ()

void
gtk_menu_item_toggle_size_request (GtkMenuItem *menu_item,
                                   gint *requisition);

Emits the “toggle-size-request” signal on the given item.

gtk_menu_item_toggle_size_allocate ()

void
gtk_menu_item_toggle_size_allocate (GtkMenuItem *menu_item,
                                    gint allocation);

Emits the “toggle-size-allocate” signal on the given item.

gtk_menu_item_get_reserve_indicator ()

gboolean
gtk_menu_item_get_reserve_indicator (GtkMenuItem *menu_item);

Returns whether the menu_item reserves space for the submenu indicator, regardless if it has a submenu or not.

Since: 3.0

gtk_menu_item_set_reserve_indicator ()

void
gtk_menu_item_set_reserve_indicator (GtkMenuItem *menu_item,
                                     gboolean reserve);

Sets whether the menu_item should reserve space for the submenu indicator, regardless if it actually has a submenu or not.

There should be little need for applications to call this functions.
