/*
 * File: UIWindow.cpp

 *
 * This file contains the implementation of the UIWindow class which is 
 * used to remove the creation of the toplevel widget in the main
 * function of BX generated code.  Our primary purpose for this class
 * has been to incorporate BX and VTK together in a working package.
 * However, by yanking out the VTK specifics, this class may serve 
 * other purposes as well.
 *
 * Please note that the structure of the main program generated by BX
 * must be changed to take advantage of this class.  We have locally
 * created our own version of the BX code generators for this purpose.
 *
 * VTK NOTES
 *
 *  In terms of VTK, this class assumes that there will be only
 *  one render master per application.  In addition, from the
 *  perspective of X Windows, we store the application context
 *  within this class as well (there is only one context per
 *  application).  The remaining functionality of VTK is handled
 *  by the VTKWindow class (which is incorporated as a class into
 *  the local BX pallette).
