[vtkusers] vtkGraphLayoutFilter

[Ashley Sher]

Hi all,

I'm using vtkGraphLayoutFilter to display links among entities. Anyhow, I
understand that vtkGraphLayoutFilter will change the position of the input
nodes. 

What i need to do is to display text beside these nodes. However, since the
nodes are not in the "supposingly" position i've set, my text doesn't appear
beside the nodes. 

Is there any methods to get the coordinates of the repositioned nodes, so
that i could set my text position just beside the nodes? 

If there is, can someone show me an example? 

Thanks a lot!
