Hi,

Is there a way to add SelectionListener for GraphicalEditor (GraphicalEditorWithFlyoutPalette)?

I have a jface viewer, when user selects a node in treeview i want to select matched object in GraphicalEditor.
Foe this I need listener...

What should I do?

What are you trying to do?
Why do you want to add a SelectionListener to a GraphicalEditor if you want to select something in a treeview?
-> That does not seem to make sense.

If i understand right, you want to select an object in a treeview, and the EditPart (or better the Figure) in the GraphicalEditor which belongs to this object, should be selected then. If I'm right the answer depends on the layout of your Editor
So, how is the layout of your Editor?
e.g.
-------------------------------
|TreeViewer| Editor with Parts |
-------------------------------

If that is the case then you have to do the following steps.
Make a subclass of the GraphicalEditorWithFlyoutPalette and let it implement a SelectionChangedListener Interface. Then register the subclassed GraphicalEditor as Listener in your TreeViewer. When the Selection changes you can react in your GraphicalEditor. Since GraphicalEditor knows its EditPartViewer, and the EditPartViewer has a Methode to the EditPart Registry, you can use your Modelartefact to get the EditPart belonging to the artefact from the EditPart Registry. When you have the EditPart, just use the setSelection Methode of the EditPartViewer.

Hi, in addition to Marcel's hint, I recommend you to take a look at the
class org.eclipse.gef.ui.parts.SelectionSynchronizer, which is a
generically implementats ISelectionChangedListener. Probably, you can
directly use this class for your Viewer.

Cheers,

Tony
