Do you mean you want to do something like...
var oldRollOver:Function = this.onRollOver;
this.onRollOver = function () {
trace("new onRollOver functionality");
oldRollOver(); //call pre-existing functionality
}

from the superclass ( I don't do an extend). I just want to add some
functionality to the onRollOver of the same instance of a movieclip.
it's like that:
var mc:MovieClip = this.attachMovie(MyClipClass.SymbolName,"mc",
this.getNextHighestDepth());
var tooltip:MyTooltipClass = new MyTooltipClass(mc, "tooltiptext");
in MyClipClass, there is a public function onRollOver() {}, which
works well, as long as I don't apply MyTooltipClass.
in MyTooltipClass, there I call mc.onRollOver = function() {}, which
overwrites the former onRollOver. But I just want to add something to
the existing onRollOver.
Someone?

exactly.
super.onRollOver()
will call the method in the superclass.
