minimize windows in the taskbar

I've created an application similar to the google desktop. When I
minimize it, it stays in the taskbar Tedit and in the button.


panel2.Top:=1;
panel2.Left :=750;
panel2.Width:=100;
Windows.SetParent(panel2.Handle, FindWindow('Shell_TrayWnd', nil));


But the problem I have is that if I open other windows, then the taskar
TEdit and the btn get overlapped by other minimized desktop windows in
the taskbar. Please do let me know how I can set reserved space for the
Tedit and the btn in the taskbar?


Thanks
