vtkFlRenderWindowInteractor is a class which enables you to create applications with full VTK and FLTK integration and interaction. This means that VTK renders to your FLTK UI, and your FLTK UI interacts with the VTK pipelines. Standard VTK interactor styles and picking work by default. This code has been tested successfully on Linux, SGI Irix, Sun Solaris, and Windows (NT, 2000, and XP).
