[news.eclipse.tools.gef] setting ContextMenu for TreeViewer

[gunjan_sir@xxxxxxxxx (Ved Gunjan)]

hi!
This is with the reference of my previous post " Getting menu on right 
click".
I have a SolutionExplorer view in my application which uses JFace 
TreeViewer.
I want to register actions on the view (when the right click on it he/she 
sholud get menu drop down).
I will have to do something like this...i guess
ContextMenuProvider provider = new LogicContextMenuProvider(getViewer(), 
getActionRegistry());
getViewer().setContextMenu(provider);
getSite().registerContextMenu("org.eclipse.gef.examples.logic.outline.contextmenu", 
//$NON-NLS-1$
			provider, getSite().getSelectionProvider());
		getViewer().setKeyHandler(getCommonKeyHandler())
viewer.setContextMenu(provider) 

The above viewer is an EditPartViewer,but i have a TreeViewer of JFace.
So how can i do setContextMenu() on a TreeViewer.

Hope im able to convey my situation properly.
Thanking in advance for the suggestions.
Regards
Ved
