Hi Sounds like you've got a wizard-type interface thing happening. I haven't used wxGlade but I have done similar things in GTK several times.
Try putting all the windows in a notebook widget with hidden tabs. Put the 'Next Page' button and the filename outside the notebook. This makes the filename always available and the 'Next Page' button would just switch pages in the notebook widget. Hope this is helpful Cheers Tim -- http://mail.python.org/mailman/listinfo/python-list
