Expand description

Swappable native-menu backend. One instance serves the whole app.

Required Methods§

Source

fn set_window_menu( &mut self, window_id: TeksiloWindowId, menu: NativeMenuSnapshot, poster: Arc<dyn AppEventPoster>, )

Build (or replace) the native menu for window_id from menu. For every item the user later chooses, the backend MUST post a NativeMenuEventPayload — with window_id_owner == window_id — through poster. If window_id is (or becomes) the active window, the backend should also make this menu the visible one.

Source

fn activate_window(&mut self, window_id: TeksiloWindowId)

Make window_id’s previously-set menu the active/visible one (focus follows window). No-op if that window never set a menu.

Source

fn clear_window(&mut self, window_id: TeksiloWindowId)

Forget window_id’s menu (window closed).

Source

fn update_item(&mut self, id: MenuItemId, delta: MenuItemDelta)

Apply a reactive delta to a single already-installed item.

Trait Implementations§

Source §

impl NativeMenuBackend for Box<dyn NativeMenuBackend>

Forward through a boxed backend so NativeMenuHandle::new(default_backend()) type-checks.

Source §

fn set_window_menu( &mut self, window_id: TeksiloWindowId, menu: NativeMenuSnapshot, poster: Arc<dyn AppEventPoster>, )

Build (or replace) the native menu for window_id from menu. For every item the user later chooses, the backend MUST post a NativeMenuEventPayload — with window_id_owner == window_id — through poster. If window_id is (or becomes) the active window, the backend should also make this menu the visible one.
