## Description

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.

### 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.

Example 78. A UI definition fragment with submenus

    1
    2
    3
    4
    5
    <object class="GtkMenuItem">
      <child type="submenu">
        <object class="GtkMenu"/>
      </child>
    </object>

## Details

### struct GtkMenuItem

    struct GtkMenuItem;

### gtk_menu_item_new ()

    GtkWidget *         gtk_menu_item_new                   (void);

Creates a new GtkMenuItem.

Returns : | the newly created 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.

`label` : | the text for the label
Returns : | the newly created GtkMenuItem

### 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.

`label` : | The text of the button, with an underscore in front of the mnemonic character
Returns : | a new GtkMenuItem

### gtk_menu_item_set_right_justified ()

    void                gtk_menu_item_set_right_justified   (GtkMenuItem *menu_item,
                                                             gboolean right_justified);

### Warning

`gtk_menu_item_set_right_justified` has been deprecated since version 3.2 and should not be used in newly-written code. If you insist on using it, use `gtk_widget_set_hexpand()` and `gtk_widget_set_halign()`.

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.)

`menu_item` : | a GtkMenuItem.
`right_justified` : | if `TRUE` the menu item will appear at the far right if added to a menu bar

### gtk_menu_item_get_right_justified ()

    gboolean            gtk_menu_item_get_right_justified   (GtkMenuItem *menu_item);

### Warning

`gtk_menu_item_get_right_justified` has been deprecated since version 3.2 and should not be used in newly-written code. See `gtk_menu_item_set_right_justified()`

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

`menu_item` : | a GtkMenuItem
Returns : | `TRUE` if the menu item will appear at the far right if added to a menu bar.

### gtk_menu_item_get_label ()

    const gchar *       gtk_menu_item_get_label             (GtkMenuItem *menu_item);

Sets `text` on the `menu_item` label

`menu_item` : | 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

### gtk_menu_item_set_label ()

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

Sets `text` on the `menu_item` label

`menu_item` : | a GtkMenuItem
`label` : | the text you want to set

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.

`menu_item` : | a GtkMenuItem
Returns : | `TRUE` if an embedded underline in the label indicates 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.

`menu_item` : | a GtkMenuItem
`setting` : | `TRUE` if underlines in the text indicate mnemonics

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.

`menu_item` : | a GtkMenuItem
`submenu` : | the submenu, or `NULL`. [allow-none]

### 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()`.

`menu_item` : | a GtkMenuItem
Returns : | submenu for this menu item, or `NULL` if none. [transfer none]

### 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()`.

`menu_item` : | a valid GtkMenuItem
`accel_path` : | accelerator path, corresponding to this menu item's functionality, or `NULL` to unset the current path. [allow-none]

### 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.

`menu_item` : | a valid GtkMenuItem
Returns : | the accelerator path corresponding to this menu item's functionality, or `NULL` if not set

Since 2.14

### gtk_menu_item_select ()

    void                gtk_menu_item_select                (GtkMenuItem *menu_item);

Emits the "select" signal on the given item. Behaves exactly like gtk_item_select.

`menu_item` : | the menu item

### gtk_menu_item_deselect ()

    void                gtk_menu_item_deselect              (GtkMenuItem *menu_item);

Emits the "activate" signal on the given item

`menu_item` : | the menu item

### gtk_menu_item_toggle_size_request ()

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

`menu_item` : | the menu item
`requisition` : | the requisition to use as signal data.

### 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.

`menu_item` : | the menu item.
`allocation` : | the allocation to use as signal data.

### 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.

`menu_item` : | a GtkMenuItem
Returns : | `TRUE` if `menu_item` always reserves space for the submenu indicator

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.
