Scrolling Html Formatted Text In Flash Concerning ActionScript 3 in Flash CS 3

[BlueInkAlchemist 0]

Greetings, all!

I'm using the techniques discussed in this thread on ActionScript.org to load formatted HTML text into flash. I also want to scroll said text, and for that purpose I'd like to use Flashscaper's scrollbar. I've run into a bit of a snag, however.

The text displays fine. However, the scrollbar does not appear when initiated and the mask (a red rectangle) can be seen on the right side of the content area; not the entire thing, just a red area about 5-10 pixels wide. The text can be scrolled using the mouse wheel, so the scrollbar functionality is intact. I think this has something to do with the transition within the ContentText function, but when I comment that out, the text doesn't display at all, nor does the scrollbar. Listed below are the three components to this project.

ContentText.as:

package{	import flash.display.MovieClip;	import flash.text.*;	import fl.transitions.*;	import fl.transitions.easing.*;	import flash.text.StyleSheet;	import flash.net.URLLoader;	import flash.net.URLRequest;	import flash.events.*;			public class ContentText extends MovieClip	{		private var myURLLoader:URLLoader;		private var myURLRequest:URLRequest;		private var bodyTextField:TextField;		public var contentPage:String;		public var myTransitionManager:TransitionManager;				public function ContentText(paraString:String)		{			contentPage = paraString;			myURLLoader = new URLLoader();			myURLRequest = new URLRequest("data/styles.css");			myURLLoader.addEventListener(Event.COMPLETE, onLoadCSS);			myURLLoader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);			myURLLoader.load(myURLRequest);		}		private function ioErrorHandler(evt:IOErrorEvent):void		{			trace('download failed');		}		private function onLoadCSS(event:Event):void		{			bodyTextField = new TextField();			var css:StyleSheet = new StyleSheet();			css.parseCSS(event.target.data);						myURLRequest = new URLRequest(contentPage);						bodyTextField.x = 50;			bodyTextField.y = 50;			bodyTextField.width = 200;			bodyTextField.height = 200;			bodyTextField.multiline = true;			bodyTextField.wordWrap = true;			bodyTextField.autoSize = TextFieldAutoSize.LEFT;			bodyTextField.selectable = false;			bodyTextField.styleSheet = css;			bodyTextField.condenseWhite = true;			addChild(bodyTextField);			myURLLoader.removeEventListener(Event.COMPLETE, onLoadCSS);			myURLLoader.addEventListener(Event.COMPLETE, onHTMLLoaded);			myURLLoader.load(myURLRequest);		}		private function onHTMLLoaded(evt:Event):void		{//		  trace(evt.target.data);			bodyTextField.htmlText = evt.target.data;			myTransitionManager = new TransitionManager(this);			myTransitionManager.startTransition({type:Wipe, direction:Transition.IN, duration:5.5, easing:None.easeOut});		}	}}

texttext.fla:

import ContentText; var ct:ContentText; var sb:MovieClip;ct = new ContentText("data/loremipsum.htm");ct.x = 100.0;ct.y = 50.0;addChild(ct);sb = new Scrollbar;sb.x = 500.0;sb.y = 50.0;addChild(sb);sb.init(ct,"easeOutSine",2,true,2);

I know it's a lot of code, but any help that you can provide would be greatly appreciated! :cool:

As an update, I did get this sort of working by adding a button that brings in the scrollbar as a separate function. This works after the text's transition has completed. Perhaps I can simply tie the scrollbar function to a timer that fires when the text begins to load?

Hi everyone!I am facing a terrible problem with the UIScrollBar component.The script is pretty simple. It works fine at local. When I publish it on line doesn?t work fine. The ScrollBar is invisible (it seems disable). I would really appreciate if someone could give some tip why it happens.I would really appreciate if someone help me.Thanks in advance
