Yep, mywindow.Closing += myCloseHandler should work just fine. You might need to do call the event handler type if the conversion type doesn't automatically happen (but I think the conversion will happen automatically).

That looks interesting; I found a pretty explicit article on how the 'Closing' event works at: http://msdn.microsoft.com/en-us/library/ms748948.aspx (about 1/2 way down the page). It looks like an event handler similar to mine could be used to cancel the 'Closing' event and preserve the window, but I haven't been able to determine how to attach the event handler to my window in IronPython. Would I be doing something like: mywindow.Closing += myCloseHandler to get the handler to catch the Closing event? Thanks, Ken Anything that talks about "window messages" or "subclassing" is pretty-much incompatible with WPF. What you really want to do is handle the Closing event on the WPF Window object. This will give you the opportunity to cancel.
