Expand description

Trait for a widget that has a focus flag.

Required Methods§

Source

fn focus(&self) -> FocusFlag

Access to the flag for the rest.

Source

fn area(&self) -> Rect

Area for mouse focus.

This area shouldn’t overlap with areas returned by other widgets. If it does, the widget should use z_areas() for clarification. Otherwise, the areas are searched in order of addition.
