[vtkusers] integrate a vtkOrientationMarkerWidget into aQVtkWidget

[John Platt]

Hi,

This is the essence of what I do in a QVTKWidget derived class ...

    m_vtkRenderer = vtkRenderer::New();
    vtkRenderWindow* renWin = GetRenderWindow();
    renWin->AddRenderer( m_vtkRenderer );

    m_vtkAxesWidget = vtkOrientationMarkerWidget::New();
    m_vtkAxesWidget->SetDefaultRenderer( m_vtkRenderer );
    vtkRenderWindowInteractor* rwi = 
m_vtkRenderer->GetRenderWindow()->GetInteractor();
    m_vtkAxesWidget->SetInteractor( rwi );

    vtkAxesActor* axes = vtkAxesActor::New();
    m_vtkAxesWidget->SetOrientationMarker ( axes );
    axes->Delete();

m_vtkRenderer & m_vtkAxesWidget are class members.

HTH

John.
