[vtkusers] problem while using vtkRenderWindowInteractor

[varshini varshini]

Hai all,

I am displaying a 3D image (using tcl in windows 2000) and wanted to add 
vtkBoxWidget for it. When I added the following lines:

vtkRenderWindowInteractor iren
iren SetRenderWindow renWin3D

I get errors saying that  " object named:iren couldn't find requested  
method:ExposeEvent or the method was called with incorrect arguments".


I am adding the renderer in a rendererwindow, which in turn is displayed 
using vtkTkRenderWidget.
If the interactor is used in the rendererwindow without TKRenderWidget it 
works fine.

Is there something that I am missing to include while using the 
TKRenderWidget or is it is something else causing me this problem?Any help 
will be greatly appreciated.

Thanks in advance

varshini
