How to implement the MVC-pattern in Tkinter
I know this is quite old but I was able to find some decent examples using the MVC pattern with both Tk and wxPython, hopefully they provide some help for anyone stumbling upon this question.
wxPython: http://wiki.wxpython.org/ModelViewController
Tk: http://tkinter.unpythonic.net/wiki/ToyMVCThis website no longer exists so I've hosted the code on a Gist here.
Here's an interesting example:https://sukhbinder.wordpress.com/2014/12/25/an-example-of-model-view-controller-design-pattern-with-tkinter-python/
I would also recommend this book where the author goes through how to structure your Tkinter application in a model-view way:https://www.packtpub.com/application-development/tkinter-gui-application-development-hotshot
