FP Digital Media [Video] wxFormBuilder: Build a Python Gif Viewer - 4

This is part 4 of building a GIF viewer with python, wxPython widgets and building the GUI using wxFormBuilder.

In the last tutorial we added main loop code to the wxFormBuilder generated code. But this didn’t work because we have to sanitise or should I say clean thehad problems running the GIF viewer application because we have to sanitise and more code to fix it.

In this tutorial I explain:

why you had to create three directories: descode, fb and src
why the wxFormBuider generated python code doesn’t work when you try to run it with a python main loop
what needs to be done to fix the generated code by creating a frameCleaner.py script

Here is the frameCleaner.py code:

# frameCleaner.py

import os

def cleanFrame(prjDir,filename):
    srcFile = os.path.join(prjDir+'\descode',filename+'.py')
    f=open(srcFile,'r')
    codein = f.read()
    codein = codein.replace('\t','    ')
    codein = codein.replace('m_','')
    f.close()
    
    # ----- Save src code
    outFile = os.path.join(prjDir+'\src',filename+'.py')
    f=open(outFile,'w')
    f.write(codein)
    f.close()
    return 'complete'

prjDir = r"C:\Python27\wxFormBuilder\fb-templates\gif-viewer"
filename = "gifviewer"

print 'Cleaning descode file: %s' % (filename+'.py')

outStat = cleanFrame(prjDir,filename)

print 'Clean descode file and save in src folder %s.' % (outStat)

# frameCleaner.py

import os

def cleanFrame(prjDir,filename):

srcFile = os.path.join(prjDir+'\descode',filename+'.py')

f=open(srcFile,'r')

codein = f.read()

codein = codein.replace('\t',' ')

codein = codein.replace('m_','')

f.close()

# ----- Save src code

outFile = os.path.join(prjDir+'\src',filename+'.py')

f=open(outFile,'w')

f.write(codein)

f.close()

return 'complete'

prjDir = r"C:\Python27\wxFormBuilder\fb-templates\gif-viewer"

filename = "gifviewer"

print 'Cleaning descode file: %s' % (filename+'.py')

outStat = cleanFrame(prjDir,filename)

print 'Clean descode file and save in src folder %s.' % (outStat)
