Hi,

Trying svgViewer.py example I have this error:

Traceback (most recent call last):
File "svgviewer2.py", line 236, in wheelEvent
factor = QtCore.qPow(1.2, event.delta() / 240.0)
AttributeError: 'module' object has no attribute 'qPow'

qPow() is undocumented, anymore in Q Assistant.

I've modified wheelEvent() with

factor = 1 + 0.1 * event.delta() / 120.0

and that's work, but I am curious, what makes qPow() ?

Power ?, not possible, result is too big.

Cheers

Thanks Juan José, good link, any of these functions are documented in Q Assistant.

... and I'm wrong when I say the result is too big :(
