Qt4 warning: QWidget::repaint: Recursive repaint detected
Message 1 in thread
Hi
I am porting a Qt3 application to Qt4 and I keep getting a lot of these
warnings:
QWidget::repaint: Recursive repaint detected
QPaintEngine::setSystemRect: Should not be changed while engine is active
QPaintEngine::setSystemClip: Should not be changed while engine is active
.
.
.
I use Qt-4.2.2, g++ 4.1.1 20060525 on a fedora core 5 box, and I have
used qt3to4 on the code.
I tried using Q3Painter instead of QPainter, and when I did so most of
the warnings disappeared. However, I am still getting a few, does
anybody know what may be causing them?
