QtPy is a compatibility layer which allows to use the code written for PyQt5 with any python Qt binding: PyQt4, PyQt5, pyside or pyside2. Main differences in PyQt5: - all widget classes are now in QtWidgets package, not QtGui; - QString obsoleted by unicode (sip API 2); - changed the way of signals connection. Closes: #1191
