Recently, I've been thinking hard about what makes code maintainable, and how to write code to be maintainable. This interest has partly been driven by the mentoring of those starting out in C++ that I've been doing, both through the ACCU mentored developers program, and for work.

The principles I've identified have not really been hidden; since they've been widely documented for years, and they're actually things that most good developers do as a matter of course. However, as with many things, you don't necessarily realize their benefits until you rediscover them yourself.

This is a collection of notes I have made while porting an application from MFC to wxWidgets. It is intended partly as a tutorial and partly to document some of the roadblocks I met on the way.

In this, the final part of the series, Jon rounds off the port of an application from MFC to wxWidgets.
