[vtkusers] Problem with creating a UI using KWWidgets

[Sharwari Mavalankar]

hi all,
I am working on creating a UI using KWWidgets.
I want to display a 3D volume in this UI from 2D BMP slices.
The volume rendering is working fine without the UI.But I seem to have some
problem with the UI.
It displays the UI window, but I cannot see the 3D volume inside it.
Addionally on running the program I get the following error on the vtkoutput
window.

ERROR: In C:\Program

 app->Script("pack %s -expand y -fill both -anchor c -expand
y",renderwidget->GetWidgetName());

 win->Display();
 app->Start();



 win->Display();
 app->Start();


 return(0);

}

Can someone please help me out.

Thanks
