A common front-end to PySide and PyQt4
With this module, you can import the QtGui and QtCore submodules from
qt_helpers, and it will automatically pick one between PyQt4 and PySide:
from qt_helpers import QtGui, QtCore
By default, qt_helpers will first try and import from PyQt4, then PySide.
To explicitly force which backend package to use, you can set the QT_API
environment variable to 'pyqt' or 'pyside'.
Note that when using qt_helpers, the QString API is always set to version
2.
If you want to know which backend is being used, you can use the is_pyqt()
and is_pyside() functions.
Finally, a convenience load_ui(filename) function is provided to load Qt
.ui files, e.g.:
from qt_helpers import load_ui
ui = load_ui('mywidget.ui')
If you define any custom widgets that are used in the .ui file, you
should pass them as a list or tuple to load_ui using the
custom_widgets= argument.
