// Name: No names yet.
// Purpose: Contrib. demo
// Author: Aleksandras Gluchovas
// Modified by: 19990908 : mj
// - rename to tabpgwin
// - restruction of Variable declaration
// - to prevent Warnings under MingW32
// Modified by: 19990909 : mj
// - mNoVertScroll TRUE = no / FALSE = Original Code
// the Original Code Paints a Vertical Scroll in wxPagedWindow
// which is not needed in this Version. Use TRUE for this.
