Flex :: Auto-resizing Spark TextArea Using Hero?
Jan 24, 2011I'm trying to auto-resize a Spark TextArea using Flex Hero but having no luck.
EDIT: To clarify, I want to auto-resize the TextArea when typing, so there's never a scroll bar.

View 1 RepliesFlex :: Calculating Spark TextArea Width?
Nov 3, 2010I am treating a spark TextArea as text input(by setting heightInLines="1"). The TextArea is part of an mxml component and I want to resize the component when the text is changed.
I haven't been able to use textArea.measureaText(textArea.text) to get line metrics and use it. I get this error "Parameter antiAliasType must be non-null."
Is there any way to get the width of a TextArea which it is going to consume at runtime for a particular string or a particular TextFlow?
Flex :: Spark TextArea Or RichText Autosize?
Apr 15, 2011I have done lots of searching on this subject, but it seems what I am finding is either out of date or just does not seem to work.With TextFields in the past, you could set the TextField to a certain width, set wordWrap to true and you would end up with a textfield that changed height according to the text you added.Now I am trying to do this with either the Spark TextArea or RichText.I tried this HeightInLines = NAN, but that seems to be out of date.I also tried this routine:
var totalHeight:uint = 10;
this.validateNow();
var noOfLines:int = this.mx_internal::getTextField().numLines;[code]....
But the mx_internal is not in the Spark components.I am trying to do this with AS3, not MXML.

Feb 6, 2012I can't seem to get TextArea to render any embedded fonts in project. I've searched online and have found a couple of instances of this issue but no solutions.
I have a few fonts embedded with my app. Spark Label & the mx:TextArea (switching embedAsCFF to 'false') will display them correctly so I know they're embedded OK. I have the fontFamily value in a binding but I even tried just instantiating a new TextArea then assigning one the the embedded fonts via the fontFamily style and have had no luck.

Flex :: Add An Image At A Specific Location In Spark TextArea Or TextFlow?

But still no joy in inserting into the middle. Also, the above code wouldn't replace highlighted text, but that's not the real concern here.Based on Eugene's link the key to this is EditManager.The following code represents the working updated function:

em.selectRange(editor.selectionAnchorPosition, editor.selectionActivePosition);

Flex :: Listen For FocusIn And FocusOut Events For A Spark TextArea?
Feb 16, 2011I am writing a flex application and I have two Spark TextAreas. I want to create an EventListener so that when the user clicks on a text area, the text inside the TextArea is cleared:
this.addEventListener(FocusEvent.FOCUS_IN, onFocusIn);
private function onFocusIn(ev:FocusEvent):void {
if (this._showsCaption) {

Currently I can implement this with a Spark TextInput, but when I click on the TextArea, the focusIn event never fires and the onFocusIn() handler is never called.

View 1 RepliesFlex :: Changing Spark TextArea Text Color Dynamically Over A Range Of Characters?
Dec 22, 2010I 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.

Actionscript 3 :: Why Is Spark TextArea Tiny When A Height And Width Are Set
Jul 19, 2010The problem, as you can see, is that the text (height and width) is nothing like the Height and Width of the compoent (Spark TextArea) that I have set via the Main.mxml file in Flex 4. This is pissing me off so much because nobody can tell me why this is happening, or how to fix it. Text is dynamically added to the TextArea as people send messages in the server, hence the valueCommit line.I don't understand this, because I know it's not the fault of my fx:Script. I know this, because when I switch over to the Design tab of Adobe Flex Builder 4; the lines are just as messed up as in the screen shot.[code]
