72/// This doesn't do a whole lot by itself, these are what `button` does:
73/// 
74/// * Add a event listener for `Hover` and `Click`
75/// * If `cursor` is set, change cutsor icon when hovering or pressing.
76/// * Propagate its status `Down`, `Click`, `Hover`, `Pressed` to its direct children.
77/// 
78/// You can use the `extra: handler!(Click => fn name() {..})` pattern to handle clicks
79/// and use [`DisplayIf`](crate::widgets::DisplayIf) for simple UI interaction.
