I've been looking for a tutorial and answer to this for a while but can't find what I'm looking for. I am loading html text into a dynamic textfield, and I have a scrollbar controlling the scroll using the code below. What I want to do is also add scroll up/down buttons and have the scroll bar move in relation to the text scroll. I was just going to use "tracklistingtext.scrollV -- " for the scroll buttons, but right now the scroll bar doesn't recognize the text movement. What do I need to do to get the scroll bar to listen to the text scroll position?
var listTextreq:URLRequest=new URLRequest("tracklist.txt");
var listTextLoader:URLLoader = new URLLoader();
var bounds:Rectangle=new Rectangle(scrollMC.x,scrollMC.y,0,300);
var scrolling:Boolean=false;
function fileLoaded(event:Event):void {
tracklistingtext.htmlText=listTextLoader.data;
tracklistingtext.multiline=true;
tracklistingtext.wordWrap=true;
scrollMC.addEventListener(MouseEvent.MOUSE_DOWN, startScroll);
stage.addEventListener(MouseEvent.MOUSE_UP, stopScroll);
addEventListener (Event.ENTER_FRAME, enterHandler);
}
listTextLoader.addEventListener(Event.COMPLETE, fileLoaded);
listTextLoader.load(listTextreq);
function startScroll(e:Event):void {
scrolling=true;
scrollMC.startDrag(false,bounds);
}
function stopScroll(e:Event):void {
scrolling=false;
scrollMC.stopDrag();
}
function enterHandler (e:Event):void {
if (scrolling == true) {
tracklistingtext.scrollV = Math.round(((scrollMC.y - bounds.y)/300)*tracklistingtext.maxScrollV);
}
}
Any help is greatly appreciated.
