Andrea:
Thanks for the help; GetTopLevelParent() works very nicely.

doesn't know anything about a variable called "frame", which is not in
the method scope. If your frame is the top level parent of the
button/textctrl, you might try something like:def OnClick(self,event):
frame = wx.GetTopLevelParent(self)
Repository(frame, -1, namefrag=self.editname.GetValue())> The error I'm getting is 'global name frame not defined'. Obviously I

retrieve the value (whatever "pythonic" means), using the wx.TextCtrl
attributes instead of the function:namefrag = self.editname.Value
Which, if I didn't make stupi mistakes, is equivalent to:
namefrag = self.editname.GetValue()
HTH.
