ActionScript 3.0 :: Detecting Change Of Text In TextField?
Jan 22, 2010
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);
[code].....

When adding textFields dynamically, as well as the TextFormat, it seems that the textFormat needs to be applied every time the text is changed. So if I have:
TxtFld.text = 'This is some text';
txtFld.setTextFormat(txtFormat);
That works. But, if i add the line:
txtFld.text = 'This is the new Text'
Then the format is lost. How can I make it so that I can change the text of the textfield, and not lose the formatting I've already applied?

I get a MovieClip from a swf that contains a TextField with the text "Test".I'm in the 1st frame and change the text to "Changed". Everything is fine.I go to the second frame of the mc but then the text is "Test" again! The changes are not made on the second frame. So I tried to change the text in the second frame too but the TextField in the mc is equal null!.

The movie I am working on has a dynamic text field which I setup and format in the constructor of the ActionScript 3.0 class code for the movie - I am working with CS3 Flash. I do not reformat the text field anywhere in the code after the constructor.The text displays in the text field perfectly as long as I do not highlight the text when running the movie.
If I highlight the text in the text box as if I were going to copy and paste, the next time text is written to the text field the font type and size changes. The only way to reset the font formatting is to restart the movie.
Is there a solution or workaround? Of course I can reformat the text everytime I write new text to the textfield, but during the course of the movie text is rewritten to the textfield many times.

I used to know how to do this, so, I KNOW it's possible, but I can't figure it out again. I'm altering the width of my TextField by setting the width property but that warps the text. I want to alter the width of the text field without altering the way the font looks (obviously). I believe it has something to do with autoText or some such idiocy (why would I ever want to warp my text?!) but I just can't recall.
myField.width = 100; //
If the original width was 50 this simply stretches the field to 100, rather than adding 50 pixels into which characters can be drawn.

I have an input text field, it's grey and italic - it says "Enter album name here". When it's clicked I want the text to go away, and change the style to black/unitalicized so the user can enter some text. Here is my event function that triggers on mouse up. The text format changes properly if I set the text to "hi", but *not* if I set the text to the empty string... Is this a bug? My experiences with Flash thus far have been far from impressive for such an expensive piece of software. Maybe I am overlooking something...

import flash.events.MouseEvent;

it is possible to change text styles of single words or lines within a textfield with actionscript. I use an empty textfield and add my text to that field in actionscript with the following code:
myTfield.text = "insert text here"
the text contains multiple lines and I want some of them to be bold, italic or a bigger font size. The reason why I am adding my text to my textfield this way is because I need the text in the textfield to change when some buttons are pressed. Text will be added or removed from the textfield if buttons are pressed by the user and the current way I'm changing the text is by simply re-using the code above with new text in it. (it makes the code quite long though, but I guess I'll have to deal with that)But because I'm adding text this way I am not sure how to change the style of different parts of the text.
On a related note, with CS5 there are now a number of options for textfields. There is TLF text and classic text. I've searched around for the differences but I don't find the awnsers very clear. What option should I use for my textfield if I want it to look sharp like the text I'm typing here (its just regular text, no headers or anything). Some options just give blurry text because of the anti-alias and some settings don't seem to change a thing. And at times embedding fonts looks nice but sometimes it makes it worse. There are so many options to choose from, but it is unclear what would work best for regular text. (my text won't animate, it does move with a scrollbar, but I only care about how it looks when the scrollbar is still)

I've created a Button in Adobe Flash CS5, it's a Symbol, and its type has been set to Button.
The button has a dynamic textfield with the instance name label.
I've set the class of this Button to MenuButton, and I've set the class to Export for ActionScript.
This is the code of the MenuButton class:
Code:
package
{
import flash.display.SimpleButton;
import flash.text.TextField;
[Code]....
Whenever I put a string in MenuButton's constructor, label's text doesn't change.

I've got a flash document using AS3. It dynamically reads data from an XML file, and creates a bunch of single line textFields. Could be like this:
<XMLdata>
<Line>this is line 1</Line>
<Line>this is line 2</Line>
<Line>this is line 3</Line>
</XMLdata>
So, for each node, it would create a new TextField, and change the textField.y value so that they are "stacked" on top of each other. All this if fine, except that if you hae so many "lines" (or textfields) that the "stack" is taller than the Flash Document size. What I would like to do is have a scroll bar or something so you can scroll the stack of TextFields. Doesnt' even need to be a scroll bar. Maybe an arrow button at the bottom, and when you click on it, it scrolls down. One for up too.

Can I detect a change to a variable (a data string)?
I am making a AS2 SWF (player level 7) with a combobox page navigation. I have a page name variable that I am changing from outside of the SWF with Director and Authorware using (I believe) FlashVars. The variable (internally) is set by default during SWF initialization. The external variables values allowed are always one of the combobox's data field values. The combobox default variable is not always index positon 0 (zero). Or the order of the data either. The variable can get changed internally by the nav combobox used for navigation independent of the external variable. - this works When the shared nav var is changed from the external source, the combobox needs to change to the match the corresponding combobox's data variable. This is what I am trying to do. I can change the combobox setting programatically (index) but not get it to recognize it as a change event. Or tell it programatically
Can the combobox be selected by the data variable or is the only option to use the index (and loop through index values to match variable to data field)?
And update the combobox selection (and as a result the nav page) by triggering a change event programatically?
Detecting the var change cleanly without the OnEnterFrame trick is my goal - if it even works in the version I have to use (flash palyer 7).

What event would signal that the visual content of an SWFLoader had changed or how would you detect that.
Actually if the visual content changes there is in fact a "render" event broadcast in the parent application, but I don't know how to determine which SWFLoader caused it.
Say you have one SWFLoader on a page that contains some sort of input control but its just sitting there doing nothing until a user presses something on it, and then there is a render event in the parent application. However, if there is another SWFLoader that contains a continually playing VideoDisplay, then there will be continal render messages being broadcast in the parent application (I verified this.) My point being that the parent application is getting signaled somehow the instant the visual content of some embedded SWFLoader changes. But the question is how does my code determine specifically which SWFLoader changed.

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.
