Testing showed it does not work, if done like this:

procedure TForm1.FormCreate(Sender: TObject);
var
  f2: TForm;
begin
  f2 := TForm2.Create(Panel2);
  f2.show;
end;

the secomd form is shown seperately and managed by the window manager.
Using MDI didn't do it either.

The last possibilities I see are streaming parts of the form myself or
using the dock manager thingy. Can someone explain how docking would be
done (or point me to the docs), please?
