How do you load .ui files onto python classes with PySide?

问题

I've used PyQt for quite a while, and the entire time I've used it, there has been a pretty consistent programming pattern.

Use Qt Designer to create a .ui file.
Create a python class of the same type as the widget you created in the .ui file.
When initializing the python class, use uic to dynamically load the .ui file onto the class.

Is there any way to do something similar in PySide? I've read through the documentation and examples and the closest thing I could find was a calculator example that pre-rendered the .ui file out to python code, which is the super old way of doing it in PyQt (why bake it to python when you can just parse the ui?)

I'm doing exactly that with PySide. :)

You use this https://gist.github.com/cpbotha/1b42a20c8f3eb9bb7cb8 (original by Sebastian Wiesner was at https://github.com/lunaryorn/snippets/blob/master/qt4/designer/pyside_dynamic.py but has disappeared) - which overrides PySide.QtUiTools.QUiLoader and supplies a new loadUi() method so that you can do this:

class MyMainWindow(QMainWindow):
    def __init__(self, parent=None):
        QMainWindow.__init__(self, parent)
        loadUi('mainwindow.ui', self)

When you instantiate MyMainWindow, it will have the UI that you designed with the Qt Designer.

If you also need to use custom widgets ("Promote To" in Qt Designer), see this answer: https://stackoverflow.com/a/14877624/532513
