[vtkusers] derive a new widget class from vtk3DWidget

[kshivann at engineering.uiowa.edu]

hi,
   does anyone have an example of a widget class derived from  
vtk3DWidget (apart from the ones already present in VTK). i have  
derived a class from vtk3DWidget. the class worked fine with VTK ver  
4.2. If i were to use the same in VTK ver 5.0 i am getting few linking  
errors when i try to access a function declared in vtk3DWidget in the  
derived class that i have written. any help is appreciated.

thanks
