The same for KDE :-(

BTW, Delphi uses a dedicated and invisible application window, in 
addition to the application main window, that shows up in the Windows 
task bar. It may be a matter of window classes or styles, so that all 
user-defined forms are treated as child windows of the application 
window, and as such never go into the taskbar. Other application windows 
are minimized to the screen, not to the taskbar, like MDI child windows.

I'd assume that other window managers offer similar features. For KDE 
it's sufficient to *hide* all forms (but the main form), when the 
application is minimized. When only the main form really is *minimized*, 
also only this form appears in the KDE taskbar.
