Hi,
I\'d like to be able to limit the resize of the edit part to its figure\'s
minimum size. I\'d also like the resize feedback not to get any smaller
than that. What\'s the best way to do this? I tried returning null command
from createChangeConstraintCommand but that only solves half the problem.
Without the feedback limit, its impossible to the user to know how far
they can resize it.
I think I can do what I need by specializing ResizeTracker to know
mimimumSize and (then ignore deltas that make it smaller than that) and
also specializing the ResizableEditPolicy to create the handles with the
new Tracker. Is this the right aproach? Seems too much work for something
that looks to me like a generally useful feature.
Thanks,
-Vadim

Thank you! I guess I wasn't looking in the right place. It still doesn't
actually limit the feedback, which would be cool, but it does work well
and resizes to minimum if user went below that. It will do just fine.
Thanks again.
