The GtkMenuItem widget and the derived widgets are the only valid childs for menus. Their function is to correctly handle highlighting, alignment, events and submenus.
As it derives from GtkBin it can hold any valid child widget, altough only a few are really useful.
The GtkMenuItem implementation of the GtkBuildable interface supports adding a submenu by specifying "submenu" as the "type" attribute of a <child> element.
Example 31. A UI definition fragment with submenus

GtkWidget* gtk_menu_item_new (void
);
Creates a new GtkMenuItem.
Returns : |
the newly created GtkMenuItem |
GtkWidget* gtk_menu_item_new_with_label (const gchar *label
);
Creates a new GtkMenuItem whose child is a GtkLabel.
|
the text for the label |
Returns : |
the newly created GtkMenuItem |
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.
|
The text of the button, with an underscore in front of the mnemonic character |
Returns : |
a new GtkMenuItem |
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.)
|
a GtkMenuItem. |
|
if TRUE the menu item will appear at the
far right if added to a menu bar.
|
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.
|
a GtkMenuItem |
Returns : |
TRUE if the menu item will appear at the
far right if added to a menu bar.
|
const gchar * gtk_menu_item_get_label (GtkMenuItem *menu_item
);
Sets text
on the menu_item
label
|
a GtkMenuItem |
Returns : |
The text in the menu_item label. This is the internal
string used by the label, and must not be modified.
|
Since 2.16
void gtk_menu_item_set_label (GtkMenuItem *menu_item
,const gchar *label
);
Sets text
on the menu_item
label
|
a GtkMenuItem |
|
the text you want to set |
Since 2.16
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.
|
a GtkMenuItem |
Returns : |
TRUE if an embedded underline in the label indicates
the mnemonic accelerator key.
|
Since 2.16
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.
|
a GtkMenuItem |
|
TRUE if underlines in the text indicate mnemonics
|
Since 2.16
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.
|
a GtkMenuItem |
|
the submenu, or NULL . [allow-none]
|
GtkWidget* gtk_menu_item_get_submenu (GtkMenuItem *menu_item
);
Gets the submenu underneath this menu item, if any. See
gtk_menu_item_set_submenu()
.
|
a GtkMenuItem |
Returns : |
submenu for this menu item, or NULL if none.
|
void gtk_menu_item_remove_submenu (GtkMenuItem *menu_item
);
gtk_menu_item_remove_submenu
has been deprecated since version 2.12 and should not be used in newly-written code. gtk_menu_item_remove_submenu()
is deprecated and
should not be used in newly written code. Use
gtk_menu_item_set_submenu()
instead.
Removes the widget's submenu.

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
persistant storage (see gtk_accel_map_save()
on this).
To setup 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()
.
|
a valid GtkMenuItem |
|
accelerator path, corresponding to this menu item's
functionality, or NULL to unset the current path. [allow-none]
|
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.
|
a valid GtkMenuItem |
Returns : |
the accelerator path corresponding to this menu item's
functionality, or NULL if not set
