static vtkInteractorStyle * New()
This class must be supplied with a vtkRenderWindowInteractor wrapper or parent.
a simple class to control print indentation
Definition: vtkIndent.h:39
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
dynamic, self-adjusting array of unsigned char
provide event-driven interface to the rendering window (defines trackball mode)
zoom in by amount indicated by rubber band box
virtual void OnMouseMove()
Generic event bindings can be overridden in subclasses.
