[vtkusers] Destroying a vtkWin32OpenGLRenderWindow

[Phil Goddard]

The following code is the part that generates the render window:

vtkRenderer *renderer = vtkRenderer::New();
vtkRenderWindow *renWin = vtkRenderWindow::New();
vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
vtkInteractorStyleTrackballCamera *style =
vtkInteractorStyleTrackballCamera::New();

renWin->AddRenderer(renderer);
iren->SetRenderWindow(renWin);
iren->SetInteractorStyle(style);

// Add the actors
renderer->AddActor(sgridActor);
renderer->AddActor(scalarBar);

// Create a bounding box
vtkCubeAxesActor2D *bbox = vtkCubeAxesActor2D::New();
bbox->SetViewProp(sgridActor);
bbox->SetCamera(renderer->GetActiveCamera());
bbox->SetFlyModeToOuterEdges();
renderer->AddViewProp(bbox);

// Set camera view
renderer->ResetCamera(0,nx,0,ny,0,nz);
renderer->GetActiveCamera()->Elevation(45.0);
renderer->GetActiveCamera()->Azimuth(30.0);
renderer->GetActiveCamera()->Zoom(0.85);

// Do the rendering
renWin->Render();


I should also add that the code is being run inside an inprocess dll from
another application.
(I am writing the dll, and it only contains the above code and the code that
generates sgridActor and scalarBar prior to the above code and appropriate
->Delete routines for the vtk objects.)

Any help's appreciated.
Phil.

	Send some code demonstrating your use of the vtkRenderWindow.
Usually, the default vtkRenderWindowInteractor will take care of closing the
render window when the user clicks on the close "x"... 

	Maybe you have a custom interactor that is not handling everything
that the default one does?
