FP Digital Media [Video] wxFormBuilder: Build a Python Gif Viewer - 9 listbox Code

We are now getting closer to finishing the Gif Viewer using python, wxpython and wxFormBuilder.

Now we add the code to populate the listbox with all Gif images found in a directory.

In this tutorial we change the file name that is converted from the descode directory to filenameBK.py

Changed frameFixCleaner.py code with filenameBK.py
