Hello,
I'm working on programmatically changing the location of a figure from
the figure's EditPart. Actually changing the location of the figure is
no problem, but when I move the figure to a location outside of its
parents bounds, it disappears. This makes sense and leads me to believe
that I need to notify the parent's layout manager to recalculate the
preferred size thereby resizing the parent to contain the child (and so
on and so on). Here's what I've tried so far:
1. invalidating the figure that moved
2. #1 and invalidating the parent
3. #2 and invalidating the layout managers of both
4. Walking up the figure tree and invalidating figures and layout managers
5. Refreshing the current EditPart
6. Refreshing the root EditPart
So obviously I'm going about it the wrong way. Is this a situation that
I should be using Requests and Commands? I've been working towards
using the GEF editing model, I just haven't grokked it quite yet.
Thanks,
Josh

Shoot, just revalidate() it, you idiot.
