At this moment i am trying the example:
http://doc.trolltech.com/4.4/widgets-imageviewer.html
But i have trouble to convert the class-method <scaleImage()>.
There is a Qt Method which is not listed in the Qt API
Library. It is named <Q_ASSERT>.
How should my PyQt4 Code looks like for this Class-Method?
I doesn't know what i have to do with <Q_ASSERT>.
Here i post the part of the example:
################################################################
void ImageViewer::scaleImage(double factor)
{
Q_ASSERT(imageLabel->pixmap());
scaleFactor *= factor;
imageLabel->resize(scaleFactor * imageLabel->pixmap()->size());
adjustScrollBar(scrollArea->horizontalScrollBar(), factor);
adjustScrollBar(scrollArea->verticalScrollBar(), factor);
zoomInAct->setEnabled(scaleFactor < 3.0);
zoomOutAct->setEnabled(scaleFactor > 0.333);
}
