FP Digital Media [Video] wxFormBuilder: Build a Python Gif Viewer - 7

Our seventh tutorial goes through the frameFixCleaner.py code to cleans up the wxFormBuilder generated python code and adds a main loop so we can run the application. In this tutorial I rehash the code to get it just right and working.

Here is the completed frameFixCleaner.py code

    cleancode = cleancode.replace('m_','')
    cleancode = cleancode.replace('    # Virtual event handlers, overide them in your derived class','')
    return cleancode   
    
def fixFrame(prjDir,filename):
    fmcode=""
    srcFile = os.path.join(prjDir+'\descode',filename+'.py')
