// Author:      Aleksandras Gluchovas
// Modified by: 19990908 : mj
//              19990909 :
//              - rename to tabpgwin
//              - restruction of Variable declaration
//              - to prevent Warnings under MingGW32
// 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.
