Catching the EVT_LIST_BEGIN_LABEL_EDIT event works for firing my

event I can fire when that popped up frame is closed so I can update my
listctrl?

You can make a custom event if you want to do it that way, but the
easiest is to just catch the frame's EVT_CLOSE and then from that
handler call some method in your listctrl class that does what you need.

I found the pubsub module actually does what I needed. I'm not sure how I
would go about catching an event that is thrown in a separate module
anyway. Thanks for the help.

That's the beauty of events. The code that wants to
catch the events tells wxPython to bind it, and then
it doesn't matter what code posts the events. The
events could come from the same module, a different
module, or whatever. It will all look the same to the
event handler.

I understand the theory of what you say, but I don't know how to execute
it. I tried the following:

<code>

def OnEditOptions(self, event):
        
       frm = Options(configLst)
       frm.Bind(wx.EVT_CLOSE, self.OnOptionsClosed)
       frm.Show()

def OnOptionsClosed(self, event):
        print 'in OnOptionsClosed!'

</code>

This only causes my print statement to execute. It doesn't close the frame
that I called. If I told the handler in the opened frame to close and did
an event.skip(), wouldn't that propagate the EVT_CLOSE to the calling app
and cause it to be closed as well?

I only started Python just over a year ago and didn't get into wxPython
until Sept. or Oct. 2006.

Thanks,

Mike

Nah, EVT_CLOSE events don't propagate like that. You
do need the event to propagate beyond your handler,
however, so it can float up to the wxPython handler
which will actually close the frame. Try:

def OnOptionsClosed(self, event):
    print 'in OnOptionsClosed!'
    event.Skip()

and it should be much happier.
