No, IIRC delphi's TApplication explicitely creates an invisible window
which subsequentally becomes a parent window for all forms' windows.
This results, for example, in that there are no separate buttons for
each form on the taskbar but just one. This invisible mega-parent is
kept in Application.Handle. It sometimes appears usefull to do

     ShowWindow(Application.Handle, SW_RESTORE);
to get user's attention :)
Best regards,
