pub fn handle_event_with( &self, cx: &mut Cx, event: &Event, scope: &mut Scope<'_, '_>, sweep_area: Area, )

§handle event with a sweep area

this is used for the sweep event, this fn can help to pass the event into popup, the widget should implement the handle_event_with fn in impl Widget for $Widget

§Example
impl Widget for Button {
fn handle_event_with(&mut self, cx: &mut Cx, event: &Event, scope: &mut Scope, sweep_area: Area) {
    let uid = self.widget_uid();

    if self.animator_handle_event(cx, event).must_redraw() {
        self.draw_button.redraw(cx);
    }
    match event.hits_with_options(cx, self.draw_button.area(), HitOptions::new().with_sweep_area(sweep_area) ) {
        Hit::FingerDown(f_down) => {
            if self.grab_key_focus {
                 cx.set_key_focus(self.sweep_area);
            }
            cx.widget_action(uid, &scope.path, GButtonEvent::Pressed(f_down.modifiers));
            self.animator_play(cx, id!(hover.pressed));
