I have a viewport whose child is a form widget and I would like to be able to tell the viewport where to position itself. For example, our form widget contains a list of times of the day along the left edge (from 12:00 AM - 11:30 PM). Whenever I draw the screen, the viewport is positioned at the top of the timelisting (i.e. 12:00), so I have to scroll down to 9:00. I would prefer the viewport to start out positioned at 9:00, instead of 12:00. In other words, I would like to change the default area to be clipped by the viewform. Current area shown upon startup: _______________________ > | 1 | | > |___| | > | 2 | | > |___| | > | 3 | | > |___| | > | 4 | | > |___| | | 5 | | |___| | | 6 | | |___| | | 7 | | |___| | | 8 | | |___|___________________| Area we want to show upon startup: _______________________ | 1 | | |___| | | 2 | | |___| | > | 3 | | > |___| | > | 4 | | > |___| | > | 5 | | > |___| | > | 6 | | > |___| | | 7 | | |___| | | 8 | | |___|___________________| If you have any questions, ask away. I need help!!! _|_o Andrew W.

Funny you should say this .. someone here came to me with the same problem, they wanted to be able to specify a new X and Y for the clipped child. Currently if you do a SetValues on the child of the Athena Viewport it refuses the request. What you need to change is the geometry manager inside the Viewport to accept the X and Y change request .. funny really, coz everything is in there to cope with moving the child (there is a MoveChild(w, x, y) procedure). I've fixed this in my own version of the Viewport (which uses different scrolly-bars) .. but as there is a need out there I'll send you diffs for Athena Viewport and also pass them on to Chris Peterson and see if he wants to include them.
