The wxPopupWindow can easily be achieved by creating a wxMiniFrame with absolutely no styles ('0', explicitly). The features of the wxPopupWindow in the wxPython demo don't come with it, they were manually added in the demo code, so simply adapting the code should suffice. Even as I was typing this message, I realized that this was probably exactly what wxPopupWindow was, and suddenly this clicked because I remembered seeing in the wxWindows help files that all of the styles for wxMiniFrame only worked on Windows and Motif, and it made a point to note that they didn't work on GTK. So I tried a snippet of code[1] on my Mac (until then I had been working on a windows box) and, to my surprise, it worked perfectly. This raises some questions for me, like why, if the wxPython package is going to have the wxPopupWindow feature, they don't simply inherit wxMiniFrame like I did (quite literally, it looks /exactly/ the same as a wxPopupWindow). Not only would this make it more multi-platform (I have no access to a GTK machine so I don't know if this works. Could someone please check?), but it would be more useful, considering the fact that it is in fact a frame, and wouldn't have the problems that M.E.Farmer outlined above regarding controls on wxPopupWindows. Regardless, I'm happy that I've uncovered the answer, and I hope this helps someone else in the same situation :) Daniel Bickett NOTES: [1] from wxPython.wx import wxMiniFrame, wxPySimpleApp app = wxPySimpleApp() frame = wxMiniFrame( None , -1 , '' , size = ( 300 , 150 ) , style = 0 ) frame.Show() app.MainLoop() -- http://mail.python.org/mailman/listinfo/python-list
