[vtkusers] Unexpected vtkTkRenderWidget

[dan]

Hi !

I have built my own Tcl interpreter (with VTK support). When I use it
vtkTkRenderWidget appeared befor I have packed it. The following code is 
an example

   vtkRenderer AtomRenderer
   vtkRenderWindow AtomRenWin
   AtomRenWin AddRenderer AtomRenderer
   vtkTkRenderWidget .atomRW -rw AtomRenWin
   vtkRenderWindowInteractor AtomIren
   AtomIren SetRenderWindow AtomRenWin
   AtomRenWin Render
#  pack .atomRW -padx 3 -pady 3 -fill both -expand yes

Could somebody can give me advice how to rectify this problem ???

Daniel.
