Hi,
I would like to change the appearance of a figure and update my model when
user select a figure (e.g. when I select a label in the logic editor
example, there are 4 small black squares in the corners) . Do I need to
implmenet my edit policy with the SELECTION_FEEDBACK_ROLE = "Selection
Feedback"?
But in the logic editor example, only container add SELECTION_FEEDBACK_ROLE,
not the label itself. Where in the example which in install the edit policy
for the selection feedback of the label?
Thanks for any help.
installEditPolicy(
EditPolicy.SELECTION_FEEDBACK_ROLE,
new ContainerHighlightEditPolicy());

The easiest way is to subclass SelectionEditPolicy, or copy the code from
it.
