[vtkusers] Information about autoRendering

[Francesco Babboni]

Hi to all..
I've got 4 vtkActor made by vtkDataSetMapper (one coming from
vtkContourFilter, one from vtkCubeAxesActor2D), and 2 vtkScalarBarActor, in
a single Render Window Interactor.
I don't know why every time I see the render,
I've to press R key to show the whole render.

So, I would like to know which is the method, or the group of method, to
render directly the whole VTK item group.
I've noticed that this happens everytime, also when I don't add contourActor
or axesActor to Renderer.

I'm look forward your reply!

Cheers,
Francesco

Renderer->AddActor(Actor1);
Renderer->AddActor(Actor2);
Renderer->AddActor(contourActor);
Renderer->AddActor(axesActor);
Renderer->AddActor2D(ColorBarActor1);
Renderer->AddActor2D(ColorBarActor2);
Renderer->SetBackground(0.4,0.4,0.4);

RenderWindow->AddRenderer(DemRen);
RenderWindow->SetSize(600, 600);
RenderWindowInteractor->SetRenderWindow(renWin);
RenderWindow->Render();
RenderWindowInteractor->Start();
RenderWindow->Render();
