Clip area of a canvas...

Hello...

after a looong time reading, time has come for me to write something with 
Kylix. Wll, actually porting a project form Delphi 5 to Kylix 3 OE.

Problem:

under Windows I used to write something like the following, to set a clipping 
area on a tcanvas, so that nothing would be drawn outside the bounds:

ClipRgn:=CreateRectRgn(FViewPortRect.Left, FViewPortRect.Top, 
FViewPortRect.Right+1, FViewPortRect.Bottom+1);

SelectClipRgn(ImgScreen.Canvas.Handle, ClipRgn);

but with Kylix such functions don't exist. So my question is: how do I 
"translate" the above code to gain the same result with Kylix? (provided I 
already tried to use some QTsomething... and QRegionH in place of HRGN with 
no results)

TIA
Batman
