[vtkusers] Vertex Position from vtkGraphLayoutView ? vtkRenderedGraphRepresentation::Layout is protected

[Jeff Baumes]

This was an encapsulation decision that the user of the view should not
have access to the laid-out graph, but instead the view manages the layout
internally. To sidestep the issue, you can manually perform the graph
layout outside the view and set the laid-out graph as the input to the
graph layout view. If you do this you should set the PassThrough strategy
on the view so that the view does not further change the layout.

HTH,
Jeff
