panel position of treepanel node

Is there a way to determine the (x,y) pixel position of a node in a treepanel in relation to the panel element?

The element of the node can be retrieved by

Code:

---


var record = tree.getStore().getNodeById(node.internalId);
var viewNode = Ext.fly(tree.getView().getNode(record));

//in anycase get the element of the node in the view and then...

if(viewNode){
 
  var x = viewNode.getLocalX();
  var y = viewNode.getLocalY();
}
