Re: Dynamically changing items in menu

[Luc Le Blanc]

Here's my code for that:

enum    // dynamic menu item IDs, followed by separator IDs
{
    FirstDynamicMenu            = 3000,
    OptionsAdjustBrightness     = FirstDynamicMenu,
    OptionsAdvancedFeatures,
    SlopeCalculator,
    BackupToCard,
    RestoreFromCard,
    ConnectGPS,
    DisconnectGPS,
    LastDynamicMenu = DisconnectGPS,
    MapSeparator,
    CaveSeparator,
    KeypadSeparator
};

A MenuItemsStringList contains strings for the menu IDs other than a separator. 
I declared several separators so as to be able to make additions in sveveral 
menus of a given menu bar.

void AddMenuItem( UInt16 after, UInt16 id, Char shortcut = '\0' );

void AddMenuItem( UInt16 after, UInt16 id, Char shortcut )
{
    Char                string[ 32 ];


    if ( id > LastDynamicMenu )
    {
        string[ 0 ] = MenuSeparatorChar;
        string[ 1 ] = chrNull;
    }
    else
        SysStringByIndex( MenuItemsStringList, id - FirstDynamicMenu, string, 
sizeof string );

    MenuAddItem( after, id, shortcut, string );
}
