[Video] wxFormBuilder: Build a Python Gif Viewer – 5
In the last tutorial you created a python script that would fix up some of the wxFormBuilder code. In this tutorial you will create a new frameFixCleaner.py script that cleans up unwanted code and adds a main loop so your application will work straight away.
This is a very handy tool and as you will notice it speeds up your time in creating python GUI applications using wxFormBuilder.
Here is the frameFixCleaner.py code:
