[vtkusers] Re: vtkImagePlaneWidget problem on vtkImageData (C++)

[Adrian Wyssmann]

Well, that was the point! I get now a separate window. But i want to be able
to change the window-level in the "original" window. How can I set the
RenderWindow of the myImageViewer2? Or what have I to do? Her's my code:

...
myRenderWindow = vtkRenderWindow::New();
...
myRenderWindow->AddRenderer(myRenderer);
...
myRenderWindowInteractor = vtkRenderWindowInteractor::New();
myRenderWindowInteractor->SetRenderWindow(myRenderWindow);
...
myActor = vtkImageActor::New();
myActor->SetInput(myImageData);
myRenderer->AddActor(myActor);
...
myImageViewer2 = vtkImageViewer2::New();
myImageViewer2->SetupInteractor(myWindowInteractor);
myImageViewer2->SetInput(myImageData);
...

Not sure but usually you obtain this error with VS6 compiler when the
declaration for vtkImageViewer2 is missing.
Check you have #include "vtkImageViewer2.h" in your sources.
