Maximum window size, help needed

[Kirill K. Smirnov]

Hi,

I want to improve wineconsole a little, max hor and vert console window 
dimensions. To achieve this, I need to know maximum available size of window 
on the desktop.
  The simpliest way I found is to use GetMonitorInfo, but it does not take 
into account desktop panels. As the result, maximized window fills entire 
desktop, overlapping with KDE panel.

So the question: is there such function, smth like 
GetMaxWindowSizeWithoutDesktopPanels, which clips panels?

Thanks in advance
