Any option for QPainter::setRasterOp( ) in Qt 4.2.2

[joseph]

Hi guys,

Our team is trying to port our application from qt3.4.4 to Qt 4.2.2. The existing one is a drawing application ( Qt3.3.4) , which will draw objects ( say Line, rectangle..etc ) in Qframe.and everything is wroking perfectly in Qt3.x.

Now the problem is, in Qt3.x we were using

Qpainter::setRasterOp( )

Qpainter::setRasterOp( )

To copy to clipboard, switch view to plain text mode 

to get a clear drawned object . but while poting to Qt 4.2.2 , there is no such option like "setRasterOp( )"

Could you please let me know any option to enable " RasterOperation " in Qt 4.2.2 .
