sure:

I hope Github is ok, Caution Pascal

MUIM_Setup

MUIM_HANDLEEVENT

@Georg:
Interesting idea, but what that means? Its rather difficult process how the objects are created (because its recursive and deeply hidden in the pascal class system) so it exactly does it like you would write it in plain.
so its creating Area, Virtual Group, Scrollbox, Window, application.

But, as I said before I had a similar problem, when I did it forward in the LCL
so create order Application, Window, Scrollbox ... and always put with AddMember/Remmember into the parent object. (where it does not work this way because Init only, the child element gets destroyed again with the new parent attached)
