.on_window_event(|event| match event.event() {
      WindowEvent::CloseRequested => {
        event.window().hide().unwrap();
      }
      _ => {} // event.window().hide().unwrap();
    })

You can hide the window decorations and make a custom titlebar, this way you have total control over whether your close button should hide or close the window.
