sending signals to the calling function

[Jaco Smuts]

Go for Tim's generator idea

Had to figure it  out a while ago in order to avoid multiple threads or 
overly complex scheduling.

It is a great tool to have in your toolbox,

Hi, again...

here's a more detailed description:

at the moment, the function looks like this:

def CreateZip(self):
    bakFile = 'data_backup_NS.zip'
 
    print "\nCompressing your data...\n"
    myZip = zipfile.ZipFile(bakFile, 'w', zipfile.ZIP_DEFLATED)
 
    for file in self.FinalList:
                 print "adding", file, "..."
                 # zip doesn't support unicode
                 if isinstance(file, unicode):
                     myZip.write(file.encode('mbcs')) #good for windows
                 else:
                     myZip.write(file)
 
    myZip.close()

it works fine when called from a console application, but now I want it to
be called from a wxwindows gui also (and redirect the output to a
wxScrolledMessageDialog). if there isn't a way to "signal" the calling
function, is there a way to redirect the output of the function (it's
running on windows)?

thanx
