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