Struct kas_widgets::menu::MenuBar

pub struct MenuBar<D: Directional = Right> { /* private fields */ }

A menu-bar

This widget houses a sequence of menu buttons, allowing input actions across menus.

Implementations

impl<D> MenuBar<D>where D: Default + Directional,

pub fn new(menus: Vec<SubMenu<D::Flipped>>) -> Self

Construct a menubar

Note: it appears that MenuBar::new(..) causes a type inference error, however MenuBar::<_>::new(..) does not. Alternatively one may specify the direction explicitly: MenuBar::<_, kas::dir::Right>::new(..).

impl<D: Directional> MenuBar<D>

pub fn new_with_direction(direction: D, menus: Vec<SubMenu<D::Flipped>>) -> Self

Construct a menubar with explicit direction

pub fn builder() -> MenuBuilder<D>
