    fn area(&self) -> Rect;

    // Provided methods
    fn z_areas(&self) -> &[ZRect] { ... }

    fn gained_focus(&self) -> bool { ... }
}

Trait for a widget that has a focus flag.

Required Methods

fn focus(&self) -> &FocusFlag

Access to the flag for the rest.

fn area(&self) -> Rect

Access the area for mouse focus.

Provided Methods

fn z_areas(&self) -> &[ZRect]

The widget might have several disjointed areas. This is the case if it is showing a popup, but there might be other causes.

This is seen as a higher resolution image of the area given with area(). That means the result of area() is the union of all areas given here.

fn navigable(&self) -> bool

The widget is focusable, but doesn’t want to partake in keyboard navigation.

fn is_focused(&self) -> bool

Focused?

fn lost_focus(&self) -> bool

Just lost focus.

fn gained_focus(&self) -> bool

Just gained focus.
