[vtkusers] vtkInteractorStyle

[David Chelberg]

If I recall correctly, there was some discussion of this in the past.
You might want to check the archives.  I believe that the result was
that member functions must be declared static to be able to be passed
like this.  Otherwise you must use an ordinary function.

    You are right but this doesn't work either. I have programed a slice 
    viewer object which
    has a mapper, a render window and an interactor. Now, I'd like to define 
    my own
    vtkInteractorStyleUser. My source code is:

    ....
    vtkRenderWindowInteractor *intAct = vtkRenderWindowInteractor::New();
    vtkInteractorStyleUser *style = vtkInteractorStyleUser::New();
	style->SetLeftButtonPressMethodArgDelete(this->get_mousePos);
	intAct->SetInteractorStyle(style);
    ....

    void SliceView::get_mousePos(void *)
    {           
	...
    }

    The error I get is:

    coversion of parameter 1 from 'void (void *)' to 'void (__cdecl *) (void 
    *)' is not possible
