Callback for popup.close()

[Jeerjmin]

I would like to run the callback function after popup.close (). This is real?

You can register a listener to the close event with Popup.addCloseListener(() => {});. That callback will run on every close. But there's no way to add callbacks to the close call. The only way at the moment is to register a close listener before you call close and in the handler just remove the listener.
