Article #293: vtkFLTK 0.6.0

Created at 15:46 Jun 21, 2004 by sean.mcinerney

The 0.6.0 release of vtkFLTK features some minor API changes enabling some major magic. The Interactor Start() method is now fully implemented and will, in fact, start the FLTK event loop as well as adding an ExitEvent Observer which may be used to override the usual behavior of TerminateApp. What this means for developers is vastly improved transparency for writing either the VTK visualization pipeline or FLTK graphical interface parts of an application. Beyond a simple header inclusion, one need never refer to any vtkFLTK class specializations in order to use them ... like magic!

The Magic(tm) happens with inclusion of the vtkFLTK Instantiator and causes all RenderWindow and Interactor instances to be vtkFLTK specializations. Merely including 'vtkFLTKInstantiator.h' into any VTK C++ example will ensure its use of vtkFLTK and, most importantly, the FLTK event loop. This allows easy addition of FLTK widget interfaces to existing code. For illustration of this behind the scenes instantiation, please see the 'Simple' and 'Simple2' examples.
