in porting Qt3 to Qt4, problem with bitBlt

[impeteperry]

Hi, I am trying to rewrite a Qt3 progrom in Ot4. and I am having a problem with my resizeEvent function. In Qt3 I have

void edpForm::resizeEvent( QResizeEvent* event )
{
	QPixmap save( baseBuffer );
	baseBuffer = QPixmap(  event->size() );
	baseBuffer.fill( QColor( 240, 240, 255 ) );
	bitBlt ( &baseBuffer, 0, 0, &save );
}

void edpForm::resizeEvent( QResizeEvent* event )
{
	QPixmap save( baseBuffer );
	baseBuffer = QPixmap(  event->size() );
	baseBuffer.fill( QColor( 240, 240, 255 ) );
	bitBlt ( &baseBuffer, 0, 0, &save );
}

To copy to clipboard, switch view to plain text mode 

and now I get a "bitBlt" not declared in this scope. Going to the Qt3 to Qt4 documentation I find.

To reimplement painter backends one previously needed to reimplement the virtual function QPaintDevice::cmd(). This function is taken out and should is replaced with the function QPaintDevice::paintEngine() and the abstract class QPaintEngine. QPaintEngine provides virtual functions for all drawing operations that can be performed on a painter backend.

bitBlt() and copyBlt() are now only compatibility functions. Use QPainter::drawPixmap() instead.

It is possible I have missed somthing in a header file someplace to cause the error message and not the change from Qt3 to Qt4. If the latter is the case some help on the proper way to handle a resize event would be appreciated.

This is a graphic program which uses the buffer/bitBlt a great deal.

Thanks.
