QPrinter_Win.cpp

[Simon Rutishauser]

I've implemented quite a part of qprinter_win.cpp. Drawing graphic 
primitives should work now. 

Drawing text is a quite ugly hack in qpainter_win.cpp - maybe someone 
has a better solution for this?
The problem there in short:
You have to access some private methods of QTextEngine (or was ist 
QScriptItem, don't remember) to draw the text from within qprinter_win - 
this is not possible because qprinter_win is no _friend_ of the above 
class. Bad luck.
Drawing on the printer from within qpainter_win (which is a friend of 
the needed class) doesn't work because I haven't got the deivce context 
there.
Current solution: Drawing on a QPixmap and printing just as a normal 
pixmap.

There might be lots of bugs all over. Some code has not yet been _really_ tested, rather 
just implemented (especially the brushes and raster-op part)

I attached the complete qprinter_win.cpp (lots of code by me and I don't 
think anyone has changed anything there in the meanwhile) and a file 
containing the changed QPainter::drawTextItem() function.

Somehow cvs diff (-u) does not seem to produce usable results for me. 
Bad luck.
