Hi!
I want to select a path (multiple nodes) in my diagram and need afterwads a
list of all selected items. Does GEF provide a special EditPolicy for this
task or are there other techniques?
Regards,
Johannes

If you need selection feedback install an instance of type
"SelectionEditPolicy", see the type hierarchy, choose the one appropriate
there are several ways to retrive the selected editparts -
1. if an action should do something with selected editparts - @see
org.eclipse.gef.SelectionAction. In order to get the selection update from
the editor, the action must be present in the list
GraphicalEditor#getSelectionActions().
2. if an editpart wants to monitor other editparts selection state, may be
GraphicalEditor#getSelectedEditparts() is a way.
3. I think it's also possible to use IWorkbenchPart#getSelectedObjects(), in
this case we need to filter out the editparts from the selections.
