6 // 19990909 :
7 // - rename to tabpgwin
8 // - restruction of Variable declaration
9 // - to prevent Warnings under MingGW32
10 // Modified by: 19990909 : mj
11 // - mNoVertScroll TRUE = no / FALSE = Original Code
12 // the Original Code Paints a Vertical Scroll in wxPagedWindow
13 // which is not needed in this Version. Use TRUE for this.
