PyQt4 and Qt v5 =============== Building Against Qt v5 ---------------------- PyQt4 can be built against Qt v5 in exactly the same way that it is built against Qt v4. However only a Qt v4 compatible subset of Qt v5 is supported, specifically: - any classes added in Qt v5 *are not* supported - any new features added in Qt v5 to classes that exist in Qt v4 *are* supported - any features that are marked as deprecated in Qt v5 *are* supported. The :option:`--no-deprecated <configure.py --no-deprecated>` option to PyQt4's :program:`configure.py` can be used to disable the support for the deprecated features. This can be useful in the porting of PyQt4 applications to PyQt5.
