1. Create your context menu provider by subclassing ContextMenuProvider (
this is in the Logic sample)
2. Register the context menu provider with your viewer(s) ( this is in the
Logic sample)
3. Create Actions for each of your context menu option and register then in
the ActionsRegistery ( this is in the Logic sample )
Note: What I did was have superclass action that implements
ISelectionListener, registers itself with the Workbench selection service
and so it gets notified when there has been a selection change, and what the
new selection(s) is(are) ( this is what the SelectionAction in the Logic
example does ). This superclass Then all of my other context menu actions
subclass this. Each of my actions implemented the following....

protected void handleSelectionChanged() {
setEnabled(canPerformAction());
}

In the canPerformAction() method I check what the current selection is ( i.e
what EditParts are selected ). And based on that decides whether it should
be enabled or disabled.
Hope this is helpful.

GEF has an abstract action which does this already.
