Loading QtDesigner's .ui files in PySide

For the complete noobs at PySide and .ui files, here is a complete example:

from PySide import QtCore, QtGui, QtUiToolsdef loadUiWidget(uifilename, parent=None):    loader = QtUiTools.QUiLoader()    uifile = QtCore.QFile(uifilename)    uifile.open(QtCore.QFile.ReadOnly)    ui = loader.load(uifile, parent)    uifile.close()    return uiif __name__ == "__main__":    import sys    app = QtGui.QApplication(sys.argv)    MainWindow = loadUiWidget(":/forms/myform.ui")    MainWindow.show()    sys.exit(app.exec_())

PySide, unlike PyQt, has implemented the QUiLoader class to directly read in .ui files.From the linked documentation,

loader = QUiLoader()file = QFile(":/forms/myform.ui")file.open(QFile.ReadOnly)myWidget = loader.load(file, self)file.close()

Another variant, based on a shorter load directive, found on https://askubuntu.com/questions/140740/should-i-use-pyqt-or-pyside-for-a-new-qt-project#comment248297_141641. (Basically, you can avoid all that file opening and closing.)

import sysfrom PySide import QtUiToolsfrom PySide.QtGui import *app = QApplication(sys.argv)window = QtUiTools.QUiLoader().load("filename.ui")window.show()sys.exit(app.exec_())

Notes:

• filename.ui should be in the same folder as your .py file.
• You may want to use if __name__ == "__main__": as outlined in BarryPye's answer
