The viewport will resize after the Scroller is resized. Can you move your resize handler to the Group instead of the Scroller?
Thanks for getting back to me.
Putting the handler on the group had the same issue (that was what I was trying to do initially).
Putting the handler on the actual scrollbar apparently would work, except that I'm hiding the scrollbars so I don't get a resize event for them.
Is there maybe some other component that doesn't have any visual affordance that I can hook into for a resize indication?
When I tried moving the handler to the Group in your example above I thought it worked as you are expecting. Can you post the trace output from doing that?
Ouch. You are correct.
Now I have to figure out how my other program is different from the sample I posted.
Thanks for the help.
