Expand description

Trait governing menus, sub-menus and menu-entries

Provided methods

[src]

fn menu_is_open(&self) -> bool

Report whether one’s own menu is open

By default, this is false.

[src]

fn set_menu_path(&mut self, _mgr: &mut Manager<'_>, _target: Option<WidgetId>)

Open or close a sub-menu, including parents

Given Some(id) = target, the sub-menu with this id should open its menu; if it has child-menus, these should close; and if any ancestors are menus, these should open.

target == None implies that all menus should close.
