Hi,
Could someone please tell me how to make Label in the logic editor example
resizable? I compare the edit policy of Label (non-resizable) with
ContainerEditPolicy (used by Circuit, which is resizable), I can't tell what
make Circuit resizable.
Thank you for any help.

If you have something that is not draggable, you should probably try to make
it look like a TreeItem or ListItem. So you might show selection by
changing the background to dark blue
(ColorConstants.menuBackgroundSelected), and the font color to white
(ColorConstants.menuForegroundSelected). Maybe handles don't make sense.
Handles are not the only way to drag something. You will also need to
override EditPart.getDragTracker() to return the SelectEditPartTracker(),
which doesn't allow dragging.
