"""Script to process UI files (convert .ui to .py).
2018-02-20 11:17:03 -05:00
It compiles .ui files to be used with PyQt4, PyQt5, PySide, QtPy, PyQtGraph.
You just need to run (it has default values) from script folder.
2018-02-20 11:17:03 -05:00
To run this script you need to have these tools available on system:
2018-02-20 11:17:03 -05:00
- pyuic4 for PyQt4 and PyQtGraph
- pyuic5 for PyQt5 and QtPy
- pyside-uic for Pyside
2018-02-20 11:17:03 -05:00
Links to understand those tools:
- pyuic4: http://pyqt.sourceforge.net/Docs/PyQt4/designer.html#pyuic4
- pyuic5: http://pyqt.sourceforge.net/Docs/PyQt5/designer.html#pyuic5
- pyside-uic: https://www.mankier.com/1/pyside-uic
