ActionScript 3.0 :: Prevent Scrolling In Textarea Not By Limiting Characters
Jul 2, 2009
I need the ability to create a TextArea entity in a constrained area (i.e., it is located at x and y and is w pixels wide and h pixels high and have that never change.), containing a proportional width font. As such, no 'num char entry limit' strategy is feasible. They need to be able to fill the entire area, and if that means 1,000 period '.' characters, or 200 '#' or "W' characters, then so be it.
The two lines following this one consist of 30 periods followed by 30 Ws.
..............................
WWWWWWWWWWWWWWWWWWWWWWWWWWWWWW
I cannot limit a user to 30 characters. They need to be limited by using a TextArea that will let itself be filled until full, and then refuse further input until space is created by removing existing content. I then need to print that TextArea _as rendered on the user's screen_. Any 'scrolled' lines would be unprintable, and therefore the user's entry must be limited BEFORE any scrolling occurs, or contrariwise, when scrolling occurs, the last entered content would need to be removed and the entity forced to un-scroll. I can program this. It won't be elegant, and in fact will be quite stupid, as any programming where a change event is called with each keystroke or paste and then conditions tested is inefficient, wasteful, and well.

Is there any way? I thought "maxChars" was promising until I learned it was only for inputting text to a textfield.The XML is coming into a dynamic text box. I need to cut it off at say 500 characters and add an ellipsis.

I already know how to limit my input text to a number of characters, but how would I go about (if possible) making sure characters do not repeat? In other words, I have a ten character input text box and I want you to be able to type pretty much any character but only one of each.
Example:
AFKEIOPCNK
What I'm trying to eliminate is this:
AANHDKDDJI
If that isn't possible, I'd like to instead detect if there are repeated characters so I can just say "that's invalid".

Since I only need numbers, can I limit dynamically embedded fonts to only numerals, periods, dashes and special characters copied from the character map?

Is there a way to restrict the number of characters in the Flex Rich Text Editor? I guess there should be, since it's possible in a textarea. So, if I could get hold of the textarea contained in the rich text editor, I would be able to do it

I would like to disable copy event in the TextArea I'm using. To achieve so I added the following code block:
function initTA(){
var tf:IUITextField = body.mx_internal::getTextField();
tf.enabled = false;
}
<mx:TextArea id="body" creationComplete="initTA()" .../>
This is working fine unless the text area has lots of text inside in which case a scroll bar appears. After the scroll bar is being used by the user, the text area stopped blocking the copy event.
By the way, I am using text area for display purposes since I use rich text area format.

I am developing a Flex based window application. In that I have used a textArea, Now when I type some characters like ctrl+b, ctrl+e or ctrl+q, it shows some square characters in text area, I think these are some unicode characters but why these are being entered.
Unlike in simple textArea control on adobe example when I presses these key combination, there is nothing being entered, so why this only with me.
This is my window setup code
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"

There is an attribute .restrict but as the defined it only prevents other characters from entering the textfield, restricting the textfield to the given characters. I want to prevent characters 1-10 from entering the textfield. The code below does not work the right way.
txt.border = true; //
function down(event:KeyboardEvent):void
{

trace(escape("д"));
will print "%D0%B4", the correct URL encoding for this character (Cyrillic equivalent of "A").However, if I were to do..
myTextArea.htmlText += unescape("%D0%B4");
What gets printed is:
ô
which is of course incorrect. Simply tracing the above unescape returns the correct Cyrillic character, though! For this texarea, escaping "д" returns its unicode code-point "%u0434". I'm not sure what exactly is happening to mess this up, but...
UTF-16 ô in web encoding is: %FE%FF%00%D0%00%B4
Whereas
UTF-16 д in web encoding is: %00%D0%00%B4
So it's padding this value with something at the beginning. Why would a trace provide different text than a print to an (empty) textarea?

I am attempting to dynamically change the color of a subset/portion of text in a Spark TextArea control. Using the MX-based TextArea, I could leverage the mx.controls.textClasses.TextRange type and change the color directly as follows:
TextRange tr = new TextRange(theTextAreaControl, false, beginIndex, endIndex);
tr.color = somePredefindColor;
Input Parameters to TextRange constructor:
1st argument: The TextArea control that will provide access to the underlying textField property
2nd argument: Indicates the TextRange will not modify the content of the TextArea
3rd argument: The beginning index position in the TextArea text string
4th argument: The ending index position in the TextArea text string
How would I go about doing this for a Spark-based TextArea control? I am looking to dynamically change the font color for a range of text, not just the entire TextArea AND I cannot statically specify the font color. The problem I run into when trying to re-use the TextRange type is that the 1st argument is expected to provide the textField property, which is currently not on the Spark-based TextArea control. I thought about extending the Spark-based TextArea control to provide this accessor property but that seems like overkill and is probably not the best approach.

I have a TextArea control, and sliding the scrollbar all the way down always doesn't show all the text.I think it has something to do with me changing the typeface, because I noticed that when I do the setStyle to change the textFormat style, the textHeight value doesn't change.Has anyone ran into something like this? can I at least access the TextArea sources so I can fix this? Or is there a way to don't know, subclass it and fix it kinda easily?you can check it here: http:/[url].... if you see the scrolling texts, you can try scrolling all the way down, and then selecting the text and pulling farther down, sometimes it'll show more text. Sorry about the spanish.This is an example of a text that usually fails to scroll all the way down[code]..........

I have a web page where users can play flash games. We are now making some changes to the page which requires the games to be embedded with wmode=transparent or wmode=opaque so that we can show HTML elements on-top of the flash games. The problem is that in Internet Explorer (on all versions) the whole page scrolls if a user presses the up/down arrow keys. I've tried everything I can think of and I've spent a whole day searching for a solution without success.o far I've tried putting the game inside a iframe and I tried disabling the up/down keys with JS, none of which solves my problem.

Is this a script out there that will prevent the user from scrolling the page (page up & down) when they press the UP and DOWN arrow keys?
I have created a car game, but the only problem is the page scrolls when the player presses the arrow keys!
I've never had this problem before, usually once you activate the Flash movie then page scrolling is disabled.
When I use my arrow keys to control the car, the page in the browser scrolls up/down.
The problem with this is when you press it a few times, the page scrolls enough where you can only see half of the Flash movie or something and it ruins the game experience.
Note: When I press the UP arrow key, the car moves forward AND the page scrolls. So it's not a matter of focusing on the Flash movie.

I'm pretty familiar with Actionscript, and this one has me completely stumped. What I'm trying to do is to prevent people from scrolling a TextArea with their mouse wheel, as the TextArea is inside of a ScrollPane, and at the moment scrolling one will scroll the other (double scrolling). Initially I tried[code]...

There's an annoying bug in AIR (or in the TextArea component itself but showing up only in AIR) because of which, if you do:
my_textarea.htmlText=someLongText;
my_textarea.textField.scrollV=someValue;
the second instruction just does not work, and the textarea scrolls to the beginning (as a consequence of the first assignment). Has anyone else run into this and have you come up with any workaround?
This only happens in AIR, not FP, and only with TextArea, not with a plain input text.

if it's possible to prevent a textfield from auto-scrolling on highlight when it's height is smaller than it's autoSize height. selectable = false is not an option, and the smaller height is a requirement, can't make it proper height and then mask it.

If you have two text areas with different styles (fontFamily, weight, color etc) and you copy text from one to the other it also copies the style from the originating text area. Is there any slick way to prevent that?
Here is a sample of code that will illustrate the problem. Type some text in the top box and some text in the bottom, then copy some characters from the top box to the bottom. I'm not using htmltext.[code]...

How do you scroll an editable TextArea (Flex Hero) on a touch device? I am referring to the situation where the text does not fit in the TextArea height.When I try to tap and drag the text gets selected and not scrolled... Am I missing a something here? I am using verticalScrollPolicy = on (also tried auto).I am testing the code in the Blackberry Playbook simulator (my targeted device for my app).

A little much put in the title, but my question is just that. I have the following AS3 code for my textarea...
addChild(Texta1);
Texta1.alpha = 0;
Texta1.blendMode = BlendMode.LAYER;
[Code].....
Unfortunately, when I start placing text in this text area. Either through code or user input, the text will be placed on a new line after about 80-100 pixels. Yet I want it to start a new line after 320 pixels (it's length).

1) Each field in the form only allows 3 characters and no special characters such as @ _ ! . , etc... 2) When the user goes to the next field in the form, the previous field appears blank but the when clicking on that again, the original text appears. 3) When submitting the form, it just keeps saying "in progress" and never shows the confirmation text nor does the email get sent. There is an HTML file included with this form but I am not sure if I need to put that in as I have embedded this form into an SWF file so I don't think I need that code but let me know if I am wrong about this. I am posting both the AS code and PHP code below..

I have this line of code, it's a part of a code that generates mcs at random X and Y, it worked when I wanted it to spawn everwhere, but now i want to limit the X to 200 - 430 this is the code for spawning on all 640 (1-640) pixels of the movie:
this._x = random(640);
i've tried (200-430) but it acts as 200 minus 430 and I end up with the X being 0 somehow
Edit: Never mind, I got it... Here's how: this._x = 200 + random(230);
