The difference between the fill=, expand=, and anchor= options to the pack() function takes a while to get used to. In brief:
* fill= controls the size of a control itself * expand= controls the size of the space into which the pack() function places a control * anchor= comes into play if the size of the space exceeds the size of the control This Google Doc might be helpful: http://docs.google.com/Doc?id=dhmzfrmj_0c685rrdb It shows the effects of progressively adding various fill= and expand= clause within three statements that create and place Button controls. -John E-mail message checked by Spyware Doctor (6.0.0.386) Database version: 5.11640 http://www.pctools.com/en/spyware-doctor-antivirus/ -- http://mail.python.org/mailman/listinfo/python-list
