I did a QWT plot (with qwt 5.0.x) that has 3 sliders to scale and scroll the plot by calling "setAxisScale" and "replot()".
this plot runs into an "assert failure" when moving the sliders.
The complete error says "ASSERT: y>=0" in file c:\iwake\build_vs2005_commercial______________padd ing______________\src\gui
\painting\qpaintengine_raster_p.h, line 293
sometimes the error description is:
"ASSERT: y>m_height" ...
Visual Studio Debug Log says:
QPaintEngine::setSystemRect, should not be changed while engine is active
QPaintEngine::setSystemClip(), should not be changed while engine is active
QPixmap:perator=: Cannot assign to pixmap during painting
QWidget::repaint: recursive repaint detected.
Any help would be appreciated! I'm using QT 4.1.4
