ActionScript 3.0 :: Can't Access TLFTextField From Constructor?
Nov 15, 2010
In the first frame, a MovieClip is created by ActionScript and placed on the main stage (This "MovieClip" actually uses a base Class called TextFieldHolder which extends MovieClip.) The Movie Clip has several TLFTextFields with instance names placed at various x/y positions in the MovieClip's first frame (the first frame has a stop(); ) Here is the trouble: When I try to change the values of the text fields in the Constructor of the TextFieldHolder class, I get an error that tells me that the TLFTextFields do not exist. I have found that I can access and change these text fields at any other time or place except for in the Constructor.The strange thing about this problem is that it does not occur in all of my projects.I am currently working on several different fla files and each one used TLFTextFields in the manner that I have described above. Almost all of them are displaying the problem, but some of the earlier ones are not.

For a project i am needed to move a vast range of movieclips over time on the stage.I thought to write a class to tackle it. my little class experience tells me you can't acces the stage in the constructor. well great, just add an eventlistener for the ADDED_TO_STAGE. I wonder how to pass the stage.stageWidth to a custom class as an optional parameter.[code]

I have encountered a problem when I need to load a third-party flash in to my flash. The flash is written in an erroneous way, it access stage in the main class constructor. I know that a display object can not access to stage property until it is added to stage, and certainly can not access to stage in its main class constructor. I observe 2 cases:
- If the flash run STANDALONE, it run well: I don't know why stage is assign before its constructor
- If the flash is LOADED by my flash, it yield null reference exception as expected
In the second case, if the third-party class remain unchanged, is there a workaround that load flash?

So I usually use an object in the constructor to receive the parameters like new Class({param1:00,param2:0099,etc).To be able to access those parameters from other functions inside the class I create an object, and copy it:
Code:
public class MyClass {
var params = {};
public function MyClass(p){

have a movieclip on the stage, whose Class is "com.nestor.elements.letterKey". The class funcKey extends "key" which contains a "public var val:String". I have many instances of letterKey(asdfghj.... a full keyboard), so I'd like to use the IDE to arrange and pass variables. SO, within the Flash IDE/Library, I rightclick the symbol to access its component definition, and add a parameter for the var in the baseclass name:value,variable:var,default:whatever,type:Str ing).Now, in the constructor function for the baseclass, if I trace my variable: it is null.

CS5 AS3 - TLFTextField are in use and a requirement. I have text fields that are dynamically changed by XML for different languages. I control the fonts (Embedded, but can vary by project builds). Characters are not mono-spaced.
I need to detect if the inserted text exceeds the fixed text's area. I only want to want fully displayed characters.
I do not want to use the 'length' method that just counts the characters in the text string.
I am building in some self test for all the fields used in a 30 language users CD with captioned movies and GUI screens.

I'm using Flash CS5. I've got an embedded font loaded from an external SWF. As far as I can tell, it's embedded properly - it used to work before I switched from the classic TextField - but I needed to switch because I need the advanced ligature support. My code is:
//setting up...
var text:TFLTextField = new TLFTextField();
text.width = 530;
text.height = 330;
[Code]....
Edit: Just tried to switch the font to Arial, and it fell back to Times New Roman again. So apparently the problem is not with the embedding, but with the way I assign the font - meaning this may be less complicated than I originally thought. Scratch that, Arial worked after I changed embedFonts to false.

All I want to do is get the formatting properties of a TLFTextField and apply it to another TLFTextField. This was simple using the classic TextField:
var textFormat:TextFormat = text1.getTextFormat();
text2.setTextFormat(textFormat);
TLFTextField has a getTextFormat and setTextFormat function, but they are both very buggy. getTextFormat only works if you change the selectable property to true, otherwise it generates a null object error. setTextFormat generates a NaN error when some of the properties of the TextFormat object are not null.
The TextLayoutFormat object is supposed to be used instead for TLFTextFields. You set the object by doing the following:
var text1:TLFTextField = new TLFTextField();
var textLayoutFormat:TextLayoutFormat = new TextLayoutFormat();
var textFlow:TextFlow = text1.textFlow;
[Code]....
But this just returned null. Does anyone know how to get the TextLayoutFormat so I can apply it to another TLFTextField?

For my project I am using the following:FlashDevelop 3.3.4 RTMFlash Pro CS 5 (libraries only, no code)Some time ago we started using TLFTextfields. One of the things I had to do was include the tlfruntime.swc file from the Adobe Flash CS 5 folder in the FlashDevelop project. Note that I copied this file to the project folder and included it, I didn't just include the file straight from the CS5 path. I have since been given a new computer that has Flash CS 5.5. I recompiled one of my swf libraries in CS 5.5, and now when I run the program, I get:Illegal override of createTextLine in flashx.textLayout.compose.ComposeStateI figure the tlfruntime.swc being included in the FlashDevelop project is out of date and needs to be updated with the one from CS 5.5. So I copied the tlfruntime.swc from the CS 5.5 path, include it in the FlashDevelop project (instead of the older file), but now I get this:
Illegal override of softKeyboardActivatingHandler infl.text.container.TLFContainerController.Can anyone assist with what else I need to do to get TLFTextfields working again in CS 5.5?UPDATE: I have updated FlashDevelop to 4.0.1 RTM, and now I get this error:Illegal override of createGeometry in flashx.textLayout.elements.FlowGroupElement.

I'm using flash cs5.5 and usually when i make a text field, the text is cut off by the width of the text field unless i autosize it, but with TLFTextField, it just resizes itself without me telling it to. How do i set the TLFTextField so that the text stays within a certain width and crops everything past that width?

Can anyone tell me what's the problem with this code ?
PHP Code:
var dataTextField:TLFTextField=new TLFTextField();
addChild(dataTextField);
this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress);
this.loaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onProgress(e:ProgressEvent):void
[Code]...
it's a preloading code and it's simple, the code used to be with "TextField" and it worked OK, then I changed it to be with "TLFTextField" class but it doesn't work now. Maybe the solution is simple but I'm not familiar with the new "TLFTextField" class

Every step I take learning flash as3 reveals so many problems and most forum posts I read blame adobe and try to work around it.
I have a TFL dynamic text box and I just want to add a scroll bar to it, this is what I did:
-elderText is the instance name of the TFL text and it's value and existance changes eccording to users choises. -elderScrollBar is a scroll bar is a UIScrollBar component I added to library, and created an instance in stage. Both are removed from stage by code.
and this is the code:
addChild(elderText);addChild(elderScrollBar);
elderScrollBar.scrollTarget = elderText; // on this line the error occures
if I delete the last line there is no error and the scroll bar appears where it should but without functioning.

I've a assets swc file that contains several TLFTextField objects, each one with it's style (font, color, size).
I use the following code to set a link:
var text_tf : TLFTextField;
var url : String = "www.stackoverflow.com";
text_tf.htmlText = "<a href='http://" + url + "' target='_blank'>"+url+"</a>";
This works as expected, but it changes the color of the text to blue;
What's the easiest way to configure the color of the text, without having to recreate all the TLF mechanism (ContainerController, Configuration, TextLayoutFormat, TextFlow, ParagraphElement, LinkElement, SpanElement, ...);
I was expecting something like this to work:
text_tf.textFlow.linkNormalFormat = { color:0x00ffFF, textDecoration:TextDecoration.NONE };
text_tf.textFlow.linkHoverFormat = { color:0x00ffFF, textDecoration:TextDecoration.NONE };

We have a library with a bunch of TextFields inside MovieClips. During runtime, we make an instance of one of these, run getTextFormat on it to get the formatting, then create a bunch of TextFields in code and run setTextFormat on them to give them the same formatting.
I'm trying to do the same thing but with TLFTextFields. I have the following:
var text:TLFTextField = new classFromLib();
text.selectable = true; //required for getTextFormat to work, flash bug
textFormat = text.getTextFormat();
[Code]....
If I set textFormat.leading and textFormat.letterSpacing to null before I run setTextFormat, then everything works, but obviously the text fields don't get the leading and letter spacing that the one in the library had.

I've read an XML file with various fields. I want to display one XML field in one TLFTextField and another XML field in another TLFTextField when a button is clicked. One text field has the product name the other has the product description.
This is the code but I can't seem to display anything, much less even trace any of the text string variables
ActionScript Code:
import flash.events.MouseEvent;
import fl.text.TLFTextField;
import flashx.textLayout.accessibility.TextAccImpl;
[Code]....
I'm also getting a prompt when I compile that says:
"Your content will not stream. Runtime Shared Library (RSL) preloading will require all of your content to download before the first frame will play.
To prevent this you can change the Runtime Shared Library Library Settings in the Advanced ActionScript 3.0 Settings dialog which can be raised from the Publish Settings dialog.
The Runtime Shared Libraries being preloaded are:
textLayout_1.0.0.595.swz for TLF Text"

I have a movieclip that has in it a text field (TLFTextField) and in a lower layer I have drawn a square with stroke and fill.
When the movie starts, I call
Code:
btn.buttonMode = true;
But the mouse cursor is the regular arrow instead of a hand when I mouse over the button in the areas of the textField that has no text.
I've also tried calling buttonMode=true to the text field itself, but didn't work How can I make the cursor be a hand over the TLFTextField?
