Positioning MCs according to height

[greenpear]

For extra credit, what happens when a single post is taller than columnHeight?

If i wanted to add a scrollbar like UIScrollBar.. where abouts do i need to add that scrollbar to the text?


I have this code:

    var scrollBar:UIScrollBar = new UIScrollBar();
    scrollBar.scrollTarget = newsBody;
    scrollBar.height = newsBody.height;
    scrollBar.move(newsBody.x + newsBody.width, newsBody.y);
    
    addChild(scrollBar);
                
function updateScrollBar():void{
                    scrollBar.update();
                    if (scrollBar.enabled == false) {
                        scrollBar.alpha = 0;
                    } else {
                            scrollBar.alpha = 100;
                        }
                } 

Inserted into the NewsPost class like so:

    public class NewsPost extends Sprite
    {

        public var newsBody:TextField;

        public function NewsPost( body:String)
        {
            newsBody = new TextField();
            newsBody.embedFonts = true;
            newsBody.multiline = true;
            newsBody.wordWrap = true;
            newsBody.autoSize = TextFieldAutoSize.LEFT;
            newsBody.antiAliasType = AntiAliasType.ADVANCED;
            newsBody.styleSheet = IStyleSheet(Gaia.api.getPage("index").assets.stylesheet).style;

            newsBody.htmlText = body;
            addChild(newsBody);
            
            //Create the scrollBar instance
                var scrollBar:UIScrollBar = new UIScrollBar();
                //assign the target of the scrollBar to your textfield
                //addChild(scrollBar);
                scrollBar.scrollTarget = newsBody;
                //make the height the same as the textfield
                scrollBar.height = 200;
                //Move the scrollbar to the righthand side
                //scrollBar.move(newsBody.x + newsBody.width, newsBody.y);
                //add it to the stage
                addChild(scrollBar);
                //check if it is required if so show it,put this function right after updating your textfield contents with added text
                function updateScrollBar():void{
                    scrollBar.update();
                    if (scrollBar.enabled == false) {
                        scrollBar.alpha = 0;
                    } else {
                            scrollBar.alpha = 100;
                        }
                } 

            // Positions & Sizing

            newsBody.x = 90;
            newsBody.y = newsTitle.height + 10;
            newsBody.width = 350;
        }
    } 

But it's giving me a weird 'flashy' result.. have i put this in the right spot?

Many thanks for any help.
