In flex, I have mx:Text component. How can I find how many characters can fit into it without vertical scroll for a certain height & font etc.
View 1 RepliesDoes anyone know what I need to do to get a flex text control to display cyrillic characters for example. [wvxvw? hebrew?] In addtion to the main .swf (.mxml) file there are font libraries loaded that are also in a seperate .swf The text control is subclassed from Flex.Text and in a seperated .AS file. Then to top it, the actual text in cyrillic is coming from an .xml file.I've tried "<?xml version="1.0" encoding='UTF-8' " in the main .mxml file and the xml file. I believe I've put Byte Order Marks (BOM's) for utf-8 in the .AS file and maybe some of the other files. I've compiled everything with specifying the utf-8 encoding as well. I get nothing where the characters are supposed to be.

View 1 RepliesDoes anyone know if there is a way to find the height of the text within the TextLayout class?
I am making my TextLayout objects like so:
this._textFlow = new TextFlow();
this._paragraphElement = new ParagraphElement();
this._textFlow.addChild(this._paragraphElement);
[Code].....
All the public properties I'd expect to find the height are undefined such as this._textFlow.lineHeight.
I have a text field that has 2 lines for visible text. I then pass it a string to display but the string might be to long to display all of the string. My problem is that I want to count how many characters that are NOT visible in the text field. The text field has to stay the fixed size and cannot change

View 1 RepliesI'm having sizing issues with a TabNavigator. The direct children of the TabNavigator are Canvases, and within these I am adding Images. I'm trying to resize the images to fit within the Canvas without scrollbars. The Canvas height is set to 100% of the parent, which is the TabNav. Then I'm setting the image.height = parent.height *.9. The result is that Flex is generating scrollbars because the images are too high. It appears that the root cause is that the height property of the TabNavigator is the height of the entire component, including the height of the tabs. I'm assuming therefore it also contains that little strip of space between the tabs and the children of the TabNavigator. This makes sense, but is there a property that returns only the height of the children? I'm aware of the scrollbar policy properties and I've experimented with those. I know I can also try a different multiplier for the image size to get it to fit. It just seems like there should be a property to get the size of the space for the children.
View 1 RepliesI am trying to limit then number of characters in a dynamic text box, but its just not working. I am loading the text from an external xml file and thought that this might be the problem, but to be honest it shouldnt be really... I have put this code inside the movie clip:
ActionScript Code:
this.title_mc.alpha = 0;
this.q_mc.alpha = 0;
this.a_mc.alpha = 0;

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"
[Code].....
I think this can be really easy however i'm not reaching the answer of this question. i have text inputs .......and i want to restrict the input to only Numbers...mytextbox.restrict = "0-9"; now when i try entering the values it works fine.....but but.....i doesn't accept any special characters.and i want it to atleast accept '.' because i want to accept decimal values
View 1 RepliesI'm loading a few bits of text into a dynamic textbox and I want to know if it's possible to find out the number of lines its taking up. Using the height of the textbox isn't an option as the text varies all the time.
View 1 RepliesI've created a custom component with several inline item renderers that I use as a tooltip. The height of the component is unknown, as the data contents of the component are not known until runtime.
However, when displaying the tooltip, occasionally it extends beyond the boundaries of the flash application, thus, I'd like to be able to detect this occurrence and reposition the tip.
The problem is that the height and width of the component are, apparently, not available until after being rendered by the popup manager. (i.e. they are always 0)But, I do not know any way of finding out when the popup is actually rendered and, therefore, the height/width values available.

I need a text box to change height according to an externally loaded number.
ActionScript Code:
homeText = new LoadVars();
homeText.onLoad = function(success) {
if (success) {
[Code]....
This should set _root.contentMain.home_txt (the text box) to 400 height right?
Why is it not changing the height to 400?
trace (nmbr); does show 400
how do i find out the number of properties in any element of the ArrayCollection? The structure of the ArrayCollection wud be something like:

I'm using a List control. In the renderer of the List control I've got a Repeater. Each Repeater can have a different number of items. Adding to the complexity, one of the components being repeated in the repeater is a Text control that has long text that will wrap, increasing it's height. I need to expand the height of the List completely so that there's no vertical scrollbar. How can I do this?
I tried an extremely dirty attempt at calculating the Lists height based on the data source. From the data source I can figure out the number of repeater items and the number of items in each repeater in the List's renderer. But there's no way to compensate for the wrapping of the text in the Text control.
I'm currently trying to implement an automated bug reporter for a Flex application, and would like to return error messages to a server along with the function/line number that caused the error. Essentially, I'm trying to get the getStackTrace() information without going into debug mode, because most users of the app aren't likely to have the debug version of flash player.My current method is using the UncaughtErrorEvent handler to catch errors that occur within the app, but the error message only returns the type of error that has occurred, and not the location (which means it's useless). I have tried implementing getStackTrace() myself using a function name-grabber such as [code]
but that will only work because of arguments.callee, and so won't go through multiple levels of function calls (it would never get above my error event listener).Anyone have any ideas on how to get informative error messages through the global error event handler? There seems to be some misunderstanding. I'm explicitly avoiding getStackTrace() because it returns 'null' when not in debug mode.
I have an app that has text appended to a TextArea (TA). It automatically scrolls to keep the recent line added in view. Over time, this could be a lot. Do I have to worry about this? Is there an upper limit? And, if so, how can I prune the oldest lines of text?
View 1 RepliesAs far as I know theres in no way to cahnge the alpha of a dynamic text box.

View 5 RepliesI've two text boxes to enter two string. How can i find the similar characters that the user entered
For example
First text box : jain
second text box : claton
Two "a" appers on the two strings. That is in the first entry's second position and the second entry's third position. How to find out any similar characters inside the entry
Lets say I have a string like so...
../images/work/environment/images/biz1.jpg
as you can see the set of characters of "images" in that string twice.
I need to replace the second "images" with something else. Had there only been one "images", I would have done something like this...
Code:
var url:String = "../images/work/environment/images/biz1.jpg";
// Pattern we are looking for in string
var imagesPattern:RegExp = images;
// Replace
AddThumb( url.replace(imagesPattern, "thumbs"));
Because there are two "images" this will not work.
How can you get the height of the Text component that's been created dynamically from ActionScript. For instance, if you have something like:
var temp:Text = new Text;
temp.width = 50;
temp.text = "Simple text";
how to get height of temp?
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'm creating a number of text boxs through code. I want to space them out by determining the height (one, two, three, lines of text) and adding 24 pixels space. I highlighted the code in red thats not working the way I want.
Code:
var MytextsA:Array = new Array("12345123451234512345123451234512", "secondElement", "thirdElement", "fourth");
var Args:Array = new Array("First", "second", "thirdt", "fourth4");
