[vtkusers] transformation in vtk

Sat Apr 25 10:27:23 EDT 2009

hi

i need help in vtk i want to make transformation (rotation, translating) to stl image for teeth
i have tried to use boxwidget it works well but i want to display degree of transformation on label or text field  but this failed
i think there is something with mycallback function plz see my code and i will wait for a reply 
plz i need help as soon as possible
