impl MenuIndexFromScreenCoord for DefaultMenuInstanceView

fn menu_index_from_screen_coord<T, 'a>(
    &self,
    menu: &'a Menu<T>,
    coord: Coord
) -> Option<usize>where
    T: Copy,

impl<T> View<MenuInstance<T>> for DefaultMenuInstanceViewwhere

fn view<G>(
    &mut self,
    value: &MenuInstance<T>,
    offset: Coord,
    depth: i32,
    grid: &mut G
)where
    G: ViewGrid,

Update the cells in grid to describe how a type should be rendered. This mutably borrows self to allow the view to contain buffers/caches which are updated during rendering.

impl<T> ViewSize<MenuInstance<T>> for DefaultMenuInstanceViewwhere

fn size(&mut self, data: &MenuInstance<T>) -> Size

Returns the size in cells of the rectangle containing a ui element. This allows for the implementation of decorator ui components that render a border around some inner element.
