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());

Model? How would you change the model on selection?

Any EditPolicy can decide to change the figure's appearance when the
EditPart is selected. The role is not too important unless you are
dynamically switch edit policies, or subclasses wish to remove a role added
in the superclass.

Thanks. Could you please tell me how can a editpolicy know if the figure has
been selected by the user?

Thank you again.

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