See the section on "Overriding methods" in http://ironpython.codeplex.com/SourceControl/changeset/view/60398#1011839 (IronPython_Main\Doc\dotnet-integration.rst) for more details on overriding, like dealing with ref params. We are working on making the info easily accessible, but for now, you can browse the content from the rst file.

Some time spent googling doesn't bring anything up except for IP/C# code examples containing the override keyword. For example, I want to override the Form class' OnLoad method, so I wrote a decorator to do so. class frm(Form): def __init__(self): Form.__init__(self) def override(method): def inner(*args): base = super(Form, args[0]) #args[0] is frm instance base_method = getattr(base.__thisclass__, method.__name__) method(*args) #call our method first return base_method(*args) return inner @override def OnLoad(self, evt_args): print evt_args It doesn't do anything snazzy - just prints out the EventArgs, then calls the base class Form.OnLoad. Any thoughts? Brian
