Well, now that I found out that there is an addCallback() API
I used it. Around line 300 of gmPhraseWheel it returns self.data which as as 
far as I can tell is a pointer to the data I want.
You use wxListBox.GetClientData() to get the pointer. 

Well back in gmLabJournal the callback provides me with this very pointer.
How do I get the data associated with it ?
