Thanks for your fast response. Unfortunately, I'm not a C-expert and I have no 
idea what the following code does. How is the cursor position set by this 
snippet of code ?

#define vtkSetVector3Macro(name,type) \
virtual void Set##name (type _arg1, type _arg2, type _arg3) \
  { \
  vtkDebugMacro(<< this->GetClassName() << " (" << this << "): setting " << 
#name " to (" << _arg1 << "," << _arg2 << "," << _arg3 << ")"); \
  if ((this->name[0] != _arg1)||(this->name[1] != _arg2)||(this->name[2] != 
_arg3)) \
    { \
    this->name[0] = _arg1; \
    this->name[1] = _arg2; \
    this->name[2] = _arg3; \
    this->Modified(); \
    } \
  }; \
virtual void Set##name (type _arg[3]) \
  { \
  this->Set##name (_arg[0], _arg[1], _arg[2]);\
  }
