Here's an example of using Tkinter inside Vue 5I that I wrote for SkinVue. You can actually do this now once the right TK/TCL libraries are installed (they're free from Python.org). In my opinion, TKinter is really a crudely written GUI that will frustrate almost anyone trying to write applications using it. There are much better Python GUI's out there (e.g. wxPython, PythonCARD) that e-on should consider using as a more rational solution for users wanting to write interactive Python apps.
