Hi Everybody,
Is there a way to listen in my EditorPart derived class to selection change of the nodes of CommonNavigator which is my viewer I know there must be something like this but I have spent hours on internet looking for it without any result. Can somebody please point me into right direction?
Regards,
Janusz

Sure, get a pointer to the CN part, get the viewer, and add an ISelectionChangedListener to the viewer. Don't forget to remove it or you will have a memory leak:

// Used when the navigator selection changes
_navSelectionListener = new ISelectionChangedListener()
{
public void selectionChanged(SelectionChangedEvent event)
{
// react
}
};

IViewReference ref = getWorkbenchPage()
.findViewReference("CNF view id");

CommonNavigator cn = (CommonNavigator)ref.getPart(false);
return;

CommonViewer viewer = cn.getCommonViewer();
viewer.addSelectionChangedListener(_navSelectionListener);
