"""Minimal Python 2 & 3 shim around all Qt bindings
DOCUMENTATION
Qt.py was born in the film and visual effects industry to address
the growing need for the development of software capable of running
with more than one flavour of the Qt bindings for Python - PySide,
PySide2, PyQt4 and PyQt5.
1. Build for one, run with all
2. Explicit is better than implicit
3. Support co-existence
Default resolution order:
- PySide2
- PyQt5
- PySide
- PyQt4
Usage:
>> import sys
>> from Qt import QtWidgets
>> app = QtWidgets.QApplication(sys.argv)
>> button = QtWidgets.QPushButton("Hello World")
>> button.show()
>> app.exec_()
All members of PySide2 are mapped from other bindings, should they exist.
If no equivalent member exist, it is excluded from Qt.py and inaccessible.
The idea is to highlight members that exist across all supported binding,
and guarantee that code that runs on one binding runs on all others.
