Hi all!

I am trying to make my own text scrollbar with dragger. I dont want up or down buttons just the dragger. I ve done this so far…

var scrollHeight:Number = scrollTrack._height;
var ms:Number = newsText.maxscroll;
var left = scrollTrack._x;
var right = scrollTrack._x;
var top = scrollTrack._y;
var bottom = scrollTrack._height-scrollBut._height+top;
var down:Boolean = true;
scrollBut.onPress = function() {
    startDrag(this, true, left, top, right, bottom);
    this.onMouseMove = function() {
        if (newsText.scroll>0) {
            if (down == true) {
                newsText.scroll++;
            }
        }
        if (newsText.scroll == ms) {
            down = false;
            trace(down);
            if (down == false) {
                newsText.scroll--;
            }
        }
    };
};
scrollBut.onMouseUp = function() {
    stopDrag();
    delete this.onMouseMove;
};

It scrolls till the end of text but not to the beginning…

Thanks in advance!
