[Ctk-developers] Python wrapper

[Steve Pieper]

Hi Felix -

Agreed - it would be great to have be able to import CTK into a
standard python interpreter.  Perhaps you can contribute code for
that? :)

By way of background, PySide did not exist when CTK chose to use
PythonQt.  PyQt was (and still is, I believe) only available under GPL
or commercial licenses.  PythonQt is licensed under LGPL and suited
our needs well.

Now that PySide exists, using it with CTK should be possible but I
don't think anyone has looked in detail at it.

-Steve
