TextArea component AS3
I'm having trouble both working out or finding out how to
apply an imported css file to the CS3 TextArea component. I've
frequently done this in AS2 using Flash 8, but that code no longer
works. If anyone knows could you please let me know. Here's the AS2
code I've used previously:
private function loadCss(){
var myStyle = new TextField.StyleSheet();
myStyle.load(this.CssPath+".css"); // the CssPath variable
here was supplied within an object passed through to the
constructor
textArea.styleSheet = myStyle;
loadXml();
}
Thank you Anirudh,
I have been using the TextArea component because it has code to handle scrollbars, and in Flash this component is a wrapper for a TextField object. As far as I can see this is not the case in Flex, and my AS3 code sets almost all of the TextField attributes, so I probably can't use Flex and the Flash Builder anyway. At least not without throwing all my code away.
Besides, the .swf file generated seems to be much bigger than in Flash.

Applying StyleSheet to a TextArea component
I'm finding it not possible to attach a style sheet to a
TextArea component with AS3, V3 component... Is there a workaround,
maybe accessing the TextAreas' textField..??.You'll need to roll out your own TextArea to get around the
error. Something
like this:
package
import fl.core.UIComponent;
import flash.text.TextField;
import flash.text.TextFormat;
import fl.controls.TextArea;
public class StylizedTextArea extends TextArea
public function StylizedTextArea()
super();
protected override function drawTextFormat():void {
// if no style sheet exists, call the super method
if(textField.styleSheet == null){
super.drawTextFormat();
return;
// This is where the StyleSheeting error occurs. The
TextField class will
// not allow a TextFormat to be applied if a StyleSheet
exists
// commenting this block seems to fix the error -- needs more
testing
var uiStyles:Object = UIComponent.getStyleDefinition();
var defaultTF:TextFormat = enabled ?
uiStyles.defaultTextFormat as
TextFormat : uiStyles.defaultDisabledTextFormat as
TextFormat;
textField.setTextFormat(defaultTF);
var tf:TextFormat =
getStyleValue(enabled?"textFormat":"disabledTextFormat") as
TextFormat;
if (tf != null) {
textField.setTextFormat(tf);
} else {
tf = defaultTF;
textField.defaultTextFormat = tf;
setEmbedFont();
if (_html) { textField.htmlText = _savedHTML; } -
ActionScript file using TextArea component
I have been developing applications in Flash CS5, but I coudn't stand the completely useless code editor any more, so I have installed the Flash Builder instead.
The problem I'm having now, is that I have an AS3 class that uses the TextArea component. But if I make an ActionScript project, I cannot import the TextArea class as FB doesn't seem to know about it. And I know nothing about Flex, so if I make a Flex project, I have no idea of how to combine my AS3 class with the TextArea component.
I am amazed - I thought that would be ridiculously simple, but I have been browsing Adobes sites for days now, and I'm not an inch closer to any solution.
Anyone knows something to help me?Thank you Anirudh,

Autoscrolling a TextArea Component

Thanks dude. That worked perfectly. I'm using AS2.0 at the minute and CS3.
I was trying textarea.scrollTop = textarea.scrollHeight;
but it wasnt working
Thanks again dude -
I've searched the net, joined Safaribooksonline, bought Colin
Moocks Essential Actionscript 3.0 & Actio0nscript 3.0 cookbook
and nowhere can I find out how to apply an imported css stylesheet
to a CS3 TextArea component. I used to do this all the time in AS2
and it worked a treat. The only help I can find in the CS3
authoring tool and in live docs relates to AS2 which causes errors
in my AS3 class. I'm building a custom TextAreaManager class for my
general use. If anyone knows how to do it please let me know.
Thanks
Dave TowersTry this example. It's about altering the context menu of the main application, but it might as well work for single components.
Good luck,

How can i display image in mx:TextArea Component?
I found display img tag in htmlText of mx:TextArea component
is very difficult in Flex Air
I new a simple air project in flex builder, put the code
below in it, i put a glad.png file in the src folder, every thing
is OK, when i run it, image cannot be displayed. why this happend,
I search the google for the solution, it seems there is a bug in
air, and told me to use mx:HTML coponent, but that component still
can not display img tag.
could any one help me with this?
<mx:TextArea width="100%" height="100%">
<mx:htmlText>
<![CDATA[
<a href='
http://www.adobe.com'><img
src='glad.png'/></a>Click the image to go to the Adobe
home page.
]]>
</mx:htmlText>
</mx:TextArea>I ran into a similar problem and wasn't able to find a way to have regular Flex components (like Text and TextArea) display <img> tags in their htmlText. Everything works find in a web-based Flex application, but once the same code was used in AIR, the images just wouldn't display.
I changed my display to use the mx:HTML component and everything worked fine (I was using only external images). -
How can I access the content of a textarea component?
I'm trying to use a javascript form editor in my jsf project.
The form editor writes to an html <textarea> component.
The jsp page looks like this:
<div style="height: 336px; left: 0px; top: 0px; position: absolute; width: 672px">
<script language="javascript" type="text/javascript">
tinyMCE.init({
mode : "textareas",
theme : "advanced",
</script>
<textarea cols="50" name="content" rows="15">This is some content that will be editable with TinyMCE.</textarea>
</div>
The content of the <textarea> component is changed with the editor.
What I need to do is capture that content after it has been edited.
How can I do that??
ThanksI have a similar problem. When I try to watch the rented movie a pop up says "Cannot Open: The content is not authorized" What exactly is the problem. I'm not in the US at the current moment. I'm in France. But that shouldn't be a problem right?

A few questions about using an XML file to add text into a TextArea component set as html
I'm using AS2 in Flash CS3.
I have a TextArea component in the stage that's loading its text from an XML and I've been able to use the ul and li tags to create lists. However, when I try to include a nested list it just inserts a line break between the nested list and the main list rather than indent it further. Is there a solution for this issue?
Failing that, how would I be able to add non-breaking spaces into the XML so they will render inside the TextArea component? I've tried and   without success. I scoured the net for some help with this and found some information about modifying the font embedding xml file with a new entry for the non-breaking space and that didn't work either, so that leaves me somewhat stumped.flash doesn't handle nested lists (as you now know). you can work-around that limitation using css and creating your own indent styles. css have a marginLeft property you can use.

TextArea component wont word wrap.. help!
I cant seem to get the TextArea component in Flash 8 to word
wrap. I've set the word wrap parameter to "true" but it will not
word wrap. It just puts all the text in one line. How do you fix
this? Also, is there a way to control the font size in the TextArea
component?
Thanks!ad 1. sorry but in my instance true is set by default to word
wrap option and it works.
ad 2 instanceName.setStyle("fontSize",24)
u can learn more about TextArea by lookin to the script below
( its just an example):
function setStyles(instance) {
instance.setStyle("themeColor", "blue");
instance.setStyle("color", "blue");
instance.setStyle("fontFamily", "Courier New");
instance.setStyle("fontSize", 12);
instance.setStyle("fontWeight", "bold");
instance.setStyle("backgroundColor", 0xDDE0FF);
instance.setStyle("borderStyle", "alert");
setStyles(myTextArea); -

Formatting Tags appearing in TextArea Component
I'm having an issue with TextFormat tags that are appearing
in textfields. Here's an overview of what I'm doing:
Basically, I'm trying to grab the text from a textArea
component: (myText = myTextArea.text")
Because I want to retain formatting, I have the textArea set
to be html.
Thus, myText becomes the text you see below
So the myText data is then stored in XML, but later when I
try to access it, it fills that same textArea component with the
literal code rather than the formatted text. How do I take that
TextFormat string and convert it back to it's original form? I've
tried myTextArea.htmlText but I guess that isn't it. Thanks for the
help!
Thanks!Let me make my question easier to understand: ;-)
I've got the text formatting (below) in a string. Using that
string, how do I display the text it contains correctly?
Thanks! -
TextArea Component - a href will not work locally (on CDROM)
Hi,
I have many products out there that use a TextArea Component
with an <a> tag that calls another url as in:
<a href="anotherPage.html">Click Here</a>
This functionality stop working on Flash Player 9. My old
products are useless until Adobe fixes the bug, but now I have to
figure out how a way to get around this.
Any ideas?
Thanks!!Thanks! That helps although the simptoms are new.
This was working on Flash Player 8, the version in which they
decided to bring about this sandboxes ordeal.
And now in Flash Player 9 it still works if I tell the getURL
to target a "_blank" page. It only breaks when I target "_self".
Now, that's not very secure to me.
But I wish they come up with a better solution. With the
sandbox issue the power of Flash has been rendered useless in local
devices. I'm think of developing in a different language just
because of this. -

TextArea component scrollpolicy being ignored
The scroll policy for the textArea component appears to be "auto", and that works just fine.
However, I want to be able to turn it off in certain situations, i.e., not have the scroll bar appear.
I do the following which I thought would turn it off but the scroll bar still shows up.
Any help would be appreciated.
Code Snippet:
myTF = new TextFormat("Arial", 10, 0xFFFFFF,false);
myText_mc.myTextArea.setStyle("textFormat", myTF);
myText_mc.myTextArea.verticalScrollPolicy = "OFF";
myText_mc.myTextArea.horizontalScrollPolicy = "OFF";
Thanks,
Vivianshould be all lower case
