Summary0013205: The vtkContextDevice2D set in a vtkContextView is never used as a new one is set in the vtkContextActor
DescriptionTo try to fix the issue 0013199 (http://www.vtk.org/Bug/view.php?id=13199 [^]) in my application without modify the code of VTK 5.10, I created a class inheriting from vtkOpenGLContextDevice2D (OpenGLContextDevice2D) and vtkContextView (ContextView). The class ContextView set an OpenGLContextDevice2D.

However, the device given to the items (vtkContextItem) is never the OpenGLContextDevice2D device but another vtkOpenGLContextDevice2D object (confirmed by using the method GetClassName() during a Paint event and also using the method SetStringRendererToQt()).

This other device is defined in the class vtkContextActor and set in the method vtkContextActor::Initialize() and then given to the 2D context.

I think the device defined in the vtkContextView should be removed as it has no effect on the display and seems superfluous.

I had a look at the current GIT master and it still contains the creation of a (unused) Context/Device, while the one used for rendering lives in vtkContextActor:

vtkContextView::vtkContextView()
{
  this->Context = vtkSmartPointer<vtkContext2D>::New();
  vtkOpenGLContextDevice2D *pd = vtkOpenGLContextDevice2D::New();
  this->Context->Begin(pd);
  pd->Delete();
  ...
}
