I am using QtCreator to make a vtk App. I wanted to make a section of the app that shows the vtkScalarBarActor so the USER can get a feeling for the colors their going to use for their state plot.
I have two lines in the showEvent handler for the QVTKOpenGLWidget were the color bar will live:
vtkSmartPointer lut = vtkSmartPointer::New();
vtkSmartPointer bar = vtkSmartPointer::New();
So there is no problem with the vtkLookupTable. But the vtkScalarBarActor throws the following:
/usr/local/vtk-8/include/vtk-8.2/vtkSmartPointer.h:155: error: undefined reference to `vtkScalarBarActor::New()’
Any ideas? Any help is greatly appreciated.
