Struct FocusAdapter

pub struct FocusAdapter<const N: usize = 0> {
    pub focus: FocusFlag,
    pub area: Rect,
    pub z_areas: [ZRect; N],
    pub navigation: Navigation,
}

Adapter for widgets that don’t use this library.

This can be constructed on the fly, if you have the necessary parts. You will at least need a FocusFlag stored parallel to the widget state.

Fields

focus: FocusFlag

area: Rect

z_areas: [ZRect; N]

navigation: Navigation
