[vtkusers] Troubles with New() and vtkTypeMacro

[Heidler, Kirstin (GE Oil & Gas)]

Tahnk you so much...that was the error.
I hate it when I can't read my own code anymore...  Guess I should go home soon.

You should always try to provide a compilable example of the problem (see http://www.vtk.org/Wiki/VTK/MinimalExample). It helps us debug as quickly as possible. I think the problem here is that you had vtkInteractorStyleTrackballActor in the vtkTypeMacro instead of the parent class vtkInteractorStyleTrackballCamera (see below).

#include <vtkInteractorStyleTrackballCamera.h>
#include <vtkSmartPointer.h>
#include <vtkObjectFactory.h>

class vtkKeyPressInteractorStyle : public vtkInteractorStyleTrackballCamera {
public:
    static vtkKeyPressInteractorStyle* New();
    //vtkTypeMacro(vtkKeyPressInteractorStyle,
vtkInteractorStyleTrackballActor); // errors with this.
    vtkTypeMacro(vtkKeyPressInteractorStyle,
vtkInteractorStyleTrackballCamera); // works correctly };

int main(int , char *[])
{
  return EXIT_SUCCESS;
}

Hope that helps,

David
