ActionScript 3.0 :: Detecting Text Over-run In TLFTextField
Mar 2, 2012
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 thought this would be easy but I don't seem to be getting anywhere. I've got a button with a text field in it, simple old dynamic one, not an input. I need to be able to change the htmlText value of that text field and detect it so I can change the size of the button to fit. I thought using Event.CHANGE would do it but I'm not getting the callback:
Code:
private function setListeners():void{
this.btn_text.addEventListener(Event.CHANGE, textChange);

I've got a few input text fields and a submit button on an order form I've designed. Trouble is you can only order in multiples of 2. Naturally I have a warning stating that orders must be multiples of that number but there is always room for idiocy! Lets say my order input text box is called "order" and the button used to proceed to payment is called "submit". How do I detect an ODD number entry and have it run an mc called "warning"?

I'm creating a simple quiz which has 3 questions. Each question has an input text field next to it for the user to type their answer. There is also one submit button underneath the 3 questions.
What I'm needing is some actionscript so they can only progress to the next frame by clicking the submit button once ALL 3 text fields have text in it. It doesn't have to detect any specific text, just that there is something put into each one. If there hasn't been, then it'll pop up with text asking them to complete all the questions first.

I'm working on a delivery costing system for my company using postcode input from users
For you non Brits out there UK postcodes work on two blocks of 2-4 characters each.
L2 2HH - Liverpool central
M24 2TN - suburb of Manchester
IV56 7NQ - outter Inverness
You get the idea. So the first part of a UK postcode, wether it be 2 characters or 4 characters MUST have atleast one numeric and one non-numeric character in it. How do I detect this?
At the moment I've just got my CHECK POSTCODE button to run a few functions only if my POSTCODE (input text) field length it greater or equal to 2 characters. So how do I easily detect an input of numeric and non-numerical characters without having to resort to indexOf ...a...b...c...1...2...3...?

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.

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.

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:

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.
