// But unfortunately, Iup isn't designed to handle this possibility.
// If I do not provide something for the handle now,
// Iup will skip the map process for all the widgets that go in the Dialog.
// So I have a overly clever workaround.
// I create a detached ViewGroup and use it in the Activity's place.
// The ViewGroup will still allow me to add widgets to it.
// Then when the onCreate() finally gets invoked, I can swap out the pointers.
// I will attach the ViewGroup as the contentView for the activity and all will be as expected.
// I also get to do something extra slippery here and pass a non-serialable object
// from this activity to the new one.
// Normally, you use Intents (which I am using to pass the Ihandle pointer).
// But ViewGroup is not serializable.
// But using C/JNI allows me to circumvent this restriction and pass the object.
// Keep a strong reference to the ViewGroup to keep it alive until our Activity is ready.
// (Remember to release this reference once we attach it to the new Activity).
