org.eclipse.gef.editpolicies.GraphicalEditPolicy
A GraphicalEditPolicy
is used with a GraphicalEditPart
. All
GraphicalEditPolicies are involved with the Figure in some way. They might use the
Figure to interpret Requests, or they might simply decorate the Figure with graphical
Feedback, such as selection handles.
This class provides convenience methods for accessing the host's Figure, and for adding feedback to the GraphicalViewer. This class does not handle any Request types directly.
