vtkTkImageWindowWidget bug

[Odet Christophe]

Hi everybody,

I recently sent the following message to the vtkusers list but it never
appears on
the list so I try again. The preceding mail was sent with 2 images showing
the result of the following code. Maybe this is the reason why my message
didn't appears in the list.

So here is the mail......
If somebody can try the script and tell me if he observes problems or not, I
would be very happy.

Hi,

 when using multiple vtkTkImageWindowWidget, I experienced problems
 with vtk2.3 that do nor occur with vtk2.1. The widgets are correctly
 refreshed
 with vtk2.1 and not with vtk2.3. This occurs on PCWIN98 with VC++6
with Tcl/Tk 8.0.5.

 The example source that shows this is at the end of this message and
 the resulting images are attached to this mail.

 Maybe my code is wrong, maybe it is a vtk bug. I don't know....

 Any help from VTK's gurus ?
