Handle button press

You can write a system that run in Update schedule to handle button events (hovered, pressed, none).

fn handle_button_press_system(mut events: EventReader<FaInteractionEvent>) {
    for e in events.read() {

        // it's not a button press event, return early.
        if !e.is_pressed(WidgetType::Button) {
            return;
        }

        // make sure this works only with buttons that have id provided
        if let Some(id) = e.widget_id.as_ref() {
            match id.as_str() {
                "#default-btn" => {
                    // do something when default button is pressed
                },
                "#info-btn" => {
                    // do something when info button is pressed
                }
                _ => ()
            }
        }
    }
