MHo 2008-04-09: Does someone know why a horizontal scrollbar does not work properly in conjunction with this widget? It seems that the hsb never gets updated.
D. McC 2008-04-12: Have you specified minimum column widths with the -minwidth option? I used to have this problem too, and it went away when I specified minimum widths.
MHo: No, haven't tried yet. Switched the whole GUI of my app to BWidgets because I had other problems with tile, too. MHo 09-nov-2008: With -stretch 1, the scrollbar is missing, with -stretch 0, it's there!
