How can I select an item in a tree programmatically? [message #523781]

Hello
I have a search dialog that I open from a CNF tree, which is populated with entries from the model that match the search string. When one of the entries is selected, I want the CNF tree to expand and highlight the item.

I have seen this behaviour in the IDE (though I can't recall a specific example!), so I know it's possible. Despite searching on a variety of keywords, I still haven't found a solution.

If anyone can help, I would be really grateful.

BTW, I'm not using a viewer filter for two reasons:
1. I never managed to figure out how to filter a tree!
2. If I did manage to figure out how to do it, I assume that I would end up with a list of items matching the search string, but I need to see the selected item in its tree context .

Regards, John

I just stumble over this two-years-old but unfortunately unanswered question. As I have exactly the same problem, does anybody have a practical solution?

Regards,
Gerd

Ok, this one was fairly easy ;-/

IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
if (page != null) {
    
  IViewPart view = page.findView(navigatorViewId);

  if (view != null && view instanceof CommonNavigator) {
   CommonNavigator cn = (CommonNavigator) view;
   cn.getCommonViewer().setSelection(new StructuredSelection(objToSelect));
  }
}
