[vtkusers] Mouse rotations with vtkGraphLayoutView

[madz]

I have this vtkMutableDirectedGraph which I need to rotate with mouse right
click. How do I enable this function?
Any help will be much apreciated.
Thanks.

Code-

#include <vtkSmartPointer.h>
#include <vtkPoints.h>
#include <vtkDataSetAttributes.h>
#include <vtkGraphLayoutView.h>
#include <vtkIntArray.h>
#include <vtkLookupTable.h>
#include <vtkMutableDirectedGraph.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkViewTheme.h>
#include <vtkRenderer.h>
#include <vtkCamera.h>
 
int main(int, char *[])
{
  // Create a graph
  vtkSmartPointer<vtkMutableDirectedGraph> graph =
    vtkSmartPointer<vtkMutableDirectedGraph>::New();
 
  vtkIdType v1 = graph->AddVertex();
  vtkIdType v2 = graph->AddVertex();
  vtkIdType v3 = graph->AddVertex();
  vtkIdType v4 = graph->AddVertex();
  graph->AddEdge(v1,v2);
  graph->AddEdge(v2,v3);
  //graph->AddEdge(v2,v3);
 
  // Manually set the position of the vertices
  vtkSmartPointer<vtkPoints> points =
    vtkSmartPointer<vtkPoints>::New();
  points->InsertNextPoint(-0.021752 ,0.0556542,0.133764);
  points->InsertNextPoint(-0.0297364,0.0530088,0.143996);
  points->InsertNextPoint(-0.0224155,0.0452271,0.139162);
  points->InsertNextPoint(-0.0151613,0.0582923,0.139686);

  graph->SetPoints(points);
 
  // Create the color array
  vtkSmartPointer<vtkIntArray> vertexColors =
    vtkSmartPointer<vtkIntArray>::New();
  vertexColors->SetNumberOfComponents(1);
  vertexColors->SetName("Color");
 
  vtkSmartPointer<vtkLookupTable> lookupTable =
    vtkSmartPointer<vtkLookupTable>::New();
  lookupTable->SetNumberOfTableValues(4);
  lookupTable->SetTableValue(0, 1.0, 0.0, 0.0); // red
  lookupTable->SetTableValue(1, 1.0, 1.0, 1.0); // white
  lookupTable->SetTableValue(2, 0.0, 1.0, 0.0); // green
  lookupTable->SetTableValue(3, 0.0, 0.0, 1.0); // blue
  lookupTable->Build();
 
  vertexColors->InsertNextValue(0);
  vertexColors->InsertNextValue(1);
  vertexColors->InsertNextValue(2);
  vertexColors->InsertNextValue(3);
 
  // Add the color array to the graph
  graph->GetVertexData()->AddArray(vertexColors);
 
  // Visualize
  vtkSmartPointer<vtkGraphLayoutView> graphLayoutView =
    vtkSmartPointer<vtkGraphLayoutView>::New();
  graphLayoutView->AddRepresentationFromInput(graph);
  graphLayoutView->SetLayoutStrategyToPassThrough();
  graphLayoutView->SetVertexColorArrayName("Color");
  graphLayoutView->ColorVerticesOn();
 
  vtkSmartPointer<vtkViewTheme> theme =
    vtkSmartPointer<vtkViewTheme>::New();
  theme->SetPointLookupTable(lookupTable);
 
  graphLayoutView->ApplyViewTheme(theme);
  graphLayoutView->ResetCamera();
  graphLayoutView->GetInteractor()->Initialize();
  graphLayoutView->GetRenderer()->GetActiveCamera()->Zoom(0.8);
  graphLayoutView->GetInteractor()->Start();
 
  return EXIT_SUCCESS;
}
