## Implemented Interfaces

GtkMenuItem implements AtkImplementorIface, GtkBuildable, GtkActivatable and GtkActionable.

## Includes

    #include <gtk/gtk.h>

## Description

The GtkMenuItem widget and the derived widgets are the only valid children for menus. Their function is to correctly handle highlighting, alignment, events and submenus.

As a GtkMenuItem derives from GtkBin it can hold any valid child widget, although only a few are really useful.

By default, a GtkMenuItem sets a GtkAccelLabel as its child. GtkMenuItem has direct functions to set the label and its mnemonic. For more advanced label settings, you can fetch the child widget from the GtkBin.

An example for setting markup and accelerator on a MenuItem:

    1
    2
    3
    4
    5
    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 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:

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

### CSS nodes

    1
    2
    3
    menuitem
    ├── <child>
    ╰── [arrow.right]

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.

## Functions

### 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.

#### Parameters

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.

#### Parameters

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);

`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.)

#### Parameters

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);

`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.

#### Parameters

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

#### Parameters

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

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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

### 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()`.

#### Parameters

menu_item | a GtkMenuItem |

#### Returns

submenu for this menu item, or `NULL` if none.

[nullable][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()`.

#### Parameters

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.

#### Parameters

menu_item | a valid GtkMenuItem |

#### Returns

the accelerator path corresponding to this menu item’s functionality, or `NULL` if not set.

[nullable][transfer none]

Since: 2.14
