wxpython/wxwizard gauge issue

Question

I am trying to add a Gauge to one of my pages in a wxpython app I am writing.

My standard python code reads through a folder of zip files and writes out to a CSV.

I have two questions, how can I make the range of my gauge match the number of files found and secondly how to set the value of the gauge to the count of files processed.

My entire code is below.

So I have setup a gauge on my 3rd page and as the convertFiles is operating I want the guage to update to the count value.

I have tried lots of the tutorials and getting lots of

object progress not defined

I really appreciate any help

Thanks

If you want a count of the files found in a directory, I like using Python's glob module. It returns a list of results that you can just grab a length of. If you want the number of files inside a zip file, I think you can use Python's zipfile module to pull it out via the namelist() method.

Now that that is out of the way, you can create the wx.Gauge widget with the length of the file list as the "range" parameter for the Gauge. Then at the end of your convertFiles() method, you just call the gauge's SetValue() method. The wxPython demo has an example.
