Hi,
I'm trying to implement my own layout manager for a very specialized
situation. Things work nicely all the way to the point where I do
child.setBounds(newBounds);
on each of the figure's children in the layout() method. I would have
expected that would be all there would be to it, but nothing happens --
none of the children become visible on the screen. I've tried to step
through the setBounds() method, but I can't find anything obviously
wrong; the setBounds() ends up in queuing a dirty-region which seems
reasonable enough.
If anybody has a clue as to what I've forgotten, I'd appreciate the help.
/Jesper

Following the laws of asking for help in newsgroups, I just realized
that the none of the child figures had any layout-managers. Duh.
Sorry for wasting your time.

Figures have 0 size now. This is different from the previously release when
figures had some strange hard-coded size. The purpose was to make adding a
figure more efficient.
Some figures have preferred sizes without layoutmanagers, such as Label.
