Struct Menu 

pub struct Menu(/* private fields */);

A menu object.

This may be a window menu, an application menu (macOS) or a context (right-click) menu.

Configuring menus

Currently, a menu and its items cannot be changed once created. If you need to change anything about a menu (for instance, disabling or selecting items) you need to create a new menu with the desired properties.

Implementations

impl Menu

pub fn new() -> Menu

Create a new empty window or application menu.

pub fn add_item( &mut self, id: u32, text: &str, key: Option<&HotKey>, selected: Option<bool>, enabled: bool, )

Add an item to this menu.

The id should uniquely identify this item. If the user selects this item, the responsible WinHandler’s command method will be called with this id. If the enabled argument is false, the menu item will be grayed out; the hotkey will also be disabled. If the selected argument is true, the menu will have a checkmark or platform appropriate equivalent indicating that it is currently selected. The key argument is an optional HotKey that will be registered with the system.
