[vtkusers] Problems with vtkTkRenderWidget

[jose beotegui]

Hi,

I'm using VTK 4.0 and Tcl/Tk on Windows.
I have done an interface using Tk and I've used a vtkTkRenderWidget 
to render a volume and I've packed altogether.
I wish to destroy only the vtkTkRenderWidget but appears 
a message like this:
"A TkRenderWidget is being destroyed before it 
associated vtkRenderWindow is destroyed. This is very bad and usually 
due to the order in which objects are being destroyed. 
Always destroy the vtkRenderWindow before destroying the user 
interface components".

But I've destroyed that vtkRenderWindow  before.
How can I resolve it?

Thanks in advance.

Code example


wm withdraw .
toplevel .visor
frame .visor.f1
vtkTkRenderWidget .visor.f1.video -width 400 -height 400 -rw renWin

pack .visor.f1.video -fill both -expand t
pack .visor.f1  -fill both -expand t

renWin Delete
destroy .visor.f1.video
