#[repr(transparent)]pub struct MenuItem { /* private fields */ }Expand description
The MenuItem 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 Bin it can hold any valid child widget,
although only a few are really useful.
By default, a GtkMenuItem sets a AccelLabel 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:
⚠️ The following code is in C ⚠️
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 Buildable interface supports
adding a submenu by specifying “submenu” as the “type” attribute of
a <child> element.
An example of UI definition fragment with submenus:
⚠️ The following code is in xml ⚠️
<object class="GtkMenuItem">
  <child type="submenu">
    <object class="GtkMenu"/>
  </child>
</object>CSS nodes
⚠️ The following code is in plain ⚠️
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.

Implementations
sourceimpl MenuItem
 
impl MenuItem
pub const NONE: Option<&'static MenuItem> = None
sourcepub fn with_label(label: &str) -> MenuItem
 
pub fn with_label(label: &str) -> MenuItem
sourcepub fn with_mnemonic(label: &str) -> MenuItem
 
pub fn with_mnemonic(label: &str) -> MenuItem
Creates a new MenuItem containing a label.
The label will be created using Label::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 MenuItem
sourcepub fn builder() -> MenuItemBuilder
 
pub fn builder() -> MenuItemBuilder
Creates a new builder-pattern struct instance to construct MenuItem objects.
This method returns an instance of MenuItemBuilder which can be used to create MenuItem objects.
