[PyQt] Qt5.5 / PyQt5.5 on OS X - SVG not in supportedImageFormats

[Marko Luther]

Phil,

thanks for that super fast reply. Of course I did not read that (although on the top of the document). Sorry.
So I understand that this is a runtime issue. I typed

# export DYLD_FRAMEWORK_PATH=~/Qt5.5.0/5.5/clang_64/lib/
# python3.4
>>> from PyQt5.QtGui import QImageReader
>>> print(QImageReader.supportedImageFormats())

and now I have "svg" and "svgz" among the results and the SVG QIcon are rendered as expected.

Thanks a lot for that quick help (and also for that wonderful software),
Marko
