    meny_with_ribbon.c


    Example for meny with ribbon (bar) moved by Up and Down arrows.

    You can choose colors for

    int mfc=4, mbc=7,               // meny table foregroud and background color
        tfc=11, tbc=2,              // meny title foregroud and background color
        ifc=10, ibc=6,              // meny items foregroud and background color
        bfc=1, bbc=7,               // meny item under bar foregroud and background color
        bar_item_num=3,             // item under bar

 Code of each color:

 Name        Value

Black          0
Blue           1
Green          2
Cyan           3
