    //
    // [ UPDATE:this is meanwhile fixed... ]

    // make color setting in KDE first and then in qtconfig for QApplication...
    // [ End update ]

    //                        --------------      ---------------
    // -- we don't so we won't sync
    //
    // next, there's ForegroundLink and ForegroundVisited in any section
    //               -------------      ----------------
    // -- we just map them to QPalette::Link & QPalette::LinkVisited
    //
    // third, there're alternate backgroundcolors for all sections - sure:
    //                 ------------------------        ---------
    // my alternate button color: 1st button blue, second red, third blue...
    // -- we'll do what we do for normal alternate row colors and slightly shift
    // to the foreground....
    //
    // there's a ForegroundActive color that is by default... PINK???
    //          -----------------
    // what a decent taste for aesthetics... &-}
    // -- we just leave it as it is, cause i've no idea what it shall be good for
    // (active palette text - that's gonna be fun ;-)

    // last there're ForegroundNegative, ForegroundNeutral and ForegroundPositive

    // what basically means: shifted to red, yellow and green...
