[vtkusers] VTK custom subclass: basic implementation

[Marcos]

Hi,

I'm thought there was a macro for my new class... but it was the superclass.

You're right, it was that and linking in Cmake.

Now it compiles.

It doesn't work, but it compiles.

I commented all inside OnLeftButton(), the method overriden.

And asigned my interactor to my widget:

vtkSmartPointer<DcmInteractorStyle> interactorStyle =
vtkSmartPointer<DcmInteractorStyle>::New();

widget->GetRenderWindow()->GetInteractor()->SetInteractorStyle(interactorStyle);


imageViewer->SetRenderWindow(widget->GetRenderWindow());

imageViewer->SetupInteractor(widget->GetRenderWindow()->GetInteractor());


widget->update();


My widget shouldn't do anything when I press left button but... it does the
same as always (vtkinteractorstyleimage, which is the default style because
of the vtkimageviewer2).

Thank you, Cory. At least now I can try different things to find out how to
make it work.
