Flex :: Load Text File From A List Into TextArea?
Jun 27, 2011
I have a TextArea and a DataGrid. I've populated the DataGrid with a list of text files in a directory. Now I'm trying to load the selected file into the TextArea. I'm getting a null pointer exception when selecting a file from the list, which tells me I'm not accessing it right...I think.
<s:TextArea id="mainTextField" x="0" y="0" width="730" height="523"
editable="true" enabled="true"/>
<s:DataGrid id="list" x="730" y="0" width="294" height="523" dataProvider="{files}" gridClick="listHandler(event)">

I've wrote a custom itemrenderer for a List component (Flex 3.5) which is a VBox with a Label and a TextArea wrapped inside. All works fine so far but I want the TextArea in the first itemrenderer to receive focus so that it instantly becomes editable when tabbing onto the List. Is that possible and if how would I achieve this?
I've already added an event listener that selects the item at index 0 but the textArea in it should also be focussed at that moment _list.addEventListener(FocusEvent.FOCUS_IN, onListFocusIn);
private function onListFocusIn(e:FocusEvent):void
{
_list.selectedIndex = 0;
}

I have a combobox and list component on the stage. The combobox has 3 selections. How do I get it so that each selection triggers the specific xml file to load into the list component? I can't get them to communicate to each other.

i've created two textarea fields that pull data from a textfile in the same directory and formats it with CSS. it tests fine on my computer, but when i upload it, it doesn't show the txt file contents. It's just blank. I've been looking around everywhere to try and find a solution, but i can't seem to find anything. Also, the scrollbar on the side of the textarea doesn't load in IE but loads in firefox.

I'm using AS2 in Flash CS3.I have a TextArea component in the stage that's loading its text from an XML and I've been able to use the ul and li tags to create lists. However, when I try to include a nested list it just inserts a line break between the nested list and the main list rather than indent it further. Is there a solution for this issue?Failing that, how would I be able to add non-breaking spaces into the XML so they will render inside the TextArea component? I've tried and without success. I scoured the net for some help with this and found some information about modifying the font embedding xml file with a new entry for the non-breaking space and that didn't work either, so that leaves me somewhat stumped.

A little much put in the title, but my question is just that. I have the following AS3 code for my textarea...

Texta1.alpha = 0;
Texta1.blendMode = BlendMode.LAYER;

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).

public function sendMessage():void
{
mytextarea.text = textinput.text;
textinput.text = "";

The problem I am facing is , whenever I add new line or others it replaces the previous text, I want the previous text in text area to stay there.

I have a block of html text which is displayed to the user in a TextArea. Currently, the I have embedded the HTML as an XML object within one of my classes, but this seems like a terrible design. I would like to put the HTML in an embedded file and load it into an XML or String object.
I've tried to search for how to do this, but my searches return information on embedding images and fonts, not text which can be loaded into Strings.
Is it possible to embedded text or xml files and load them into variables in Flex?

if you feed the textarea text attribute with an tag that has a valid src url, then for some reason flex will try to render everything as html.Eg, try this:<mx:TextArea id="textArea" width="100%" height="90%" text="<img src='http://url-to-a-valid-img"/> and instead of it rendering it as raw text it will render it as an html.

I am attempting to insert text from a database into a custom TextArea component, using the following:
var front:CaptionTextArea = myFlashcardFrontsides[adjIndex] as CaptionTextArea;
var back:CaptionTextArea = myFlashcardBacksides[adjIndex] as CaptionTextArea;
var passage:CaptionTextInput = myVersePassages[adjIndex] as CaptionTextInput;
front.text = passage.text;
back.text = str;
This works 100% of the time for smaller strings. However, if I insert long strings of text, the application will hang consistently. The maxchars for the textarea is set to 1200, and the text that is inserted into the text area is always smaller than the character limit:
backside.maxChars = 1200;

Take a look at this demo, how do they accomplish the Inline Changes feature? To me it looks like they are floating a movieclip over the textarea. What I can't figure out is how they anchored the movieclip to stay in the correct position. If you type something before the movieclip it moves position along with the text, the movieclips even move to the next line when the text word wraps. Does anyone have an idea?

I am trying to use a text area to display some text on a mobile AIR app. It works fine whenever I am using the phone emulator on my desktop to debug, however whenever I put the app on my phone, the text displays, then disappears. I've also noticed that if I lock the screen and unlock, the text will display just fine when I come back.
Here's the code:
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" title="Program Overview">
<fx:Declarations>

One other interesting thing to note is that it only happens on certain Views, and only on Views in the first ViewNavigator tab. This leads me to believe that there isn't really anything wrong with my use of the TextArea, but something else happening at a higher level in the application.

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.

(Flex 3) I have a TextArea component which needs to hold the user's clipboard content. The TextArea does the job relatively well for most cases but when pasting a large amount of data, I can't seem to get the content in the component at all due to the script execution timeout.
I've done a fair deal on investigation to try and hopefully find how I could make this work. I found that the TextArea is using a IUITextField (which is in my case an instance of TextField at runtime) do handle the job of obtaining the pasting data and then throws an event when it is done.
I have found no way to take a look at the source of TextField as it is a class in the playerglobal.swc library.
Is there a way for me to maybe see the source of that class or is there something I'm missing in my approach to figure out a way to make this work?
