[vtkusers] Add a menu item in VTK

[Gishara Indeewarie]

Yes, I have tried to use MFC dialog here.
But then when I try to update the data, I get an error as,  " Expression:
e->Component != 0", when closing the renderWindow.
Below is how I do it.

getData(){


vtkSmartPointer <vtkRenderer> Renderer =
 vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer <vtkRenderWindow> RenderWindow =
 vtkSmartPointer<vtkRenderWindow>::New();
vtkSmartPointer <vtkRenderWindowInteractor> Interactor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
vtkSmartPointer<vtkPolyData> polydata =
 vtkSmartPointer<vtkPolyData>::New();
vtkSmartPointer<vtkDoubleArray> weights =
 vtkSmartPointer<vtkDoubleArray>::New();
vtkSmartPointer<vtkVertexGlyphFilter> glyphFilter =
vtkSmartPointer<vtkVertexGlyphFilter>::New();
vtkSmartPointer<vtkSurfaceReconstructionFilter> surf=
 vtkSmartPointer<vtkSurfaceReconstructionFilter>::New();
vtkSmartPointer<vtkContourFilter> cf=
vtkSmartPointer<vtkContourFilter>::New();
vtkSmartPointer<vtkPolyDataMapper> mapper =
 vtkSmartPointer<vtkPolyDataMapper>::New();
vtkSmartPointer<vtkPoints> newPts = vtkSmartPointer<vtkPoints>::New();
vtkSmartPointer<vtkActor> actor= vtkSmartPointer<vtkActor>::New();



newPts->Reset();
ScalarValues.RemoveAll();

 for (plane = 0; plane <t; plane++)
{
 newPts->InsertNextPoint(pt2->xx,pt2->y,pt2->z);
ScalarValues.Add(pt2->P0);

}

}

ViewData(){

polydata->SetPoints(newPts);
  polydata->Modified();

  weights->SetNumberOfValues(ScalarValues_pressure.GetSize());
  for(int i=0; i< ScalarValues_pressure.GetSize();i++){
  weights->SetValue(i, ScalarValues_pressure[i]);
  }


  glyphFilter->SetInputConnection(polydata->GetProducerPort());
  glyphFilter->Update();

  surf->SetInput(polydata);


  cf->SetInputConnection(surf->GetOutputPort());
  cf->Update();

 outputPolyData = cf->GetOutput();
 outputPolyData->Modified();

 outputPolyData->GetPointData()->SetScalars(weights);


  mapper->SetInputConnection(cf->GetOutputPort());
  mapper->Modified();
  mapper->ScalarVisibilityOn();
  actor->SetMapper(mapper);
  actor->Modified();


  Renderer->SetBackground( 1, 1, 1 );
  Renderer->Modified();

  Renderer->AddActor(actor);
  Renderer->Modified();

  RenderWindow->AddRenderer(Renderer);
  RenderWindow->Modified();
   Interactor->SetRenderWindow(RenderWindow);
  RenderWindow->Render();
  RenderWindow->Modified();
  nteractor->Start();
  Interactor->Modified();


}
