I'm not sure how we do this stuff under the covers, but it's all pure pyGTK. - -dave Greg Ewing wrote: > If I understand correctly, firstly you're trying to create a kind > of graphical GUI-building environment, but using your own unique > kinds of widgets rather than the standard ones. > > It's hard to say what would be the best way to go about it.
