If you invoke the system 'cp' command though, it may not be possible to have a progress bar because the command will only talk back when it exits.

For me the normal copy thing is the cp command. It reads through errors quite happily...

If its a long loop or using os.walk() then you need to put it in a separate thread. Thats probably the best solution. Alternartively invoke the cp command line and run it in the background(with &), but then you won;t get suvch good error reports etc... Otherwise break it into chunks so you only copy a few files at a time and then return to the GUI. But that will slow the copy process even more! > Can anyone show me how to run the gtk and copy code as separate > processes since this seems to be the only way that the application > graphics wont hang? Thanks in advance. You don't need separate processes just separate threads. Check the Python documentation for a threading tutorial. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
