The skin for the Spark theme
uses the RichEditableText class. This means that the Spark TextArea control supports
the Text Layout Framework (TLF) library,
which builds on the Flash Text Engine (FTE).
In combination, these layers provide text editing with
high-quality international typography and layout.
The skin includes a scroller that can display horizontal and vertical scrollbars
for scrolling through the text and supports vertical scrolling with the mouse wheel.
The RichEditableText can be accessed as textDisplay
and the Scroller as scroller.
The skin for the mobile theme uses the StyleableStageText class.
Since StyleableStageText uses native text fields it allows for better text entry and
manipulation experiences on mobile devices however there are some
limitations and differences that you should consider.
Because StageText is not capable of measuring text, the TextArea must be given explicit,
percent-based, or constraint-based width and height.
The StyleableStageText can be accessed as textDisplay.
If you wish to use the TextField-based skin, rather than the
StageText-based skin, set the skinClass property to
"spark.skins.mobile.TextAreaSkin".
You can set the text to be displayed, or get the text that the user
has entered, using the text property.
The text is formatted using CSS styles such as fontFamily
and fontSize.
For the Spark theme, the widthInChars and heightInLines
properties let you specify the width and height of the TextArea
in a way that scales with the font size or you can use the typicalText property.
Note that if you use typicalText, the widthInChars and
heightInLines properties are ignored.
For all themes, you can also specify an explicit width or height in pixels,
or use a percent width and height or constraints such as
left and right
or top and bottom.
You can use the maxChars property to limit the number
of character that the user can enter, and the restrict
to limit which characters the user can enter.
To use this control for password input, set the
displayAsPassword property to true.
For the mobile theme, the soft-keyboard-specific properties, autoCapitalize,
autoCorrect, returnKeyLabel and softKeyboardType
properties specify keyboard hints.
If a soft-keyboard is present but does not support a feature represented by the
hint, the hint is ignored.
In mobile environments with only hardware keyboards, these hints are ignored.
Text Area for the Spark Theme
The most important differences between Spark TextArea and the MX TextArea control are as follows:
- Spark TextArea offers better typography, better support for international languages, and better text layout.
- Spark TextArea has an object-oriented model of rich text, while the MX version does not.
- Spark TextArea has better support for displaying large amounts of text.
- Spark TextArea requires that fonts be embedded
differently than the MX version.
To learn how to use the
embedAsCFFattribute when you embed a font, see the font documentation.
The Spark TextArea control uses the TLF object-oriented model of rich text,
in which text layout elements such as divisions, paragraphs, spans,
hyperlinks, and images are represented at runtime by ActionScript
objects. You can programmatically access and manipulate these objects.
The central object in TLF for representing rich text is a
TextFlow. Specify rich text for a TextArea control
by setting its textFlow property to a TextFlow instance.
If you don't need to display text that has multiple formats,
set the TextArea text property to a plain text string.
See the descriptions of the text and textFlow
properties for information about how they interact;
for example, you can set one and get the other.
At compile time, you can put TLF markup tags inside the TextArea tag, as the following example shows:
<s:TextArea>Hello <s:span fontWeight="bold">World!</s:span></s:TextArea>In this example, the MXML compiler sets the TextArea
content
property, causing a TextFlow object to be created from the FlowElements that you specify.
The TextArea control does not include any user interface for changing the formatting of the text but contains APIs that you can use to programmatically format text. For example, you can create a a button that, when clicked, makes the selected text bold.
The default text formatting is determined by CSS styles such as fontFamily and fontSize. Any formatting information in the TextFlow object overrides the default formatting provided by the CSS styles.
You can control many characteristics of TextArea content with styles. Here are a few popular ones:
- Control spacing between lines with the
lineHeightstyle. - Control the spacing between paragraphs with the
paragraphSpaceBeforeandparagraphSpaceAfterstyles. - Align or justify text using the
textAlignandtextAlignLaststyles. - Inset text from the border of the control using the
paddingLeft,paddingTop,paddingRight, andpaddingBottomstyles.
By default, the text wraps at the right edge of the control.
A vertical scrollbar automatically appears when there is more
text than fits in the TextArea.
If you set the lineBreak style to explicit,
new lines start only at explicit line breaks. This has the same effect as
if you use CR (\r), LF (\n),
or CR+LF (\r\n) in text,
or if you use <p> and <br/>
in TLF markup.
In those cases, a horizontal scrollbar automatically appears
if any lines of text are wider than the control.
The Spark TextArea
can display left-to-right (LTR) text, such as French,
right-to-left (RTL) text, such as Arabic, and bidirectional text,
such as a French phrase inside of an Arabic one.
If the predominant text direction is right-to-left,
set the direction style to rtl.
The textAlign style defaults to start,
which makes the text left-aligned when direction
is ltr and right-aligned when direction
is rtl. To get the opposite alignment,
set textAlign to end.
The Spark TextArea also supports unlimited undo/redo within one editing session. An editing session starts when the control gets keyboard focus and ends when the control loses focus.
To use this component in a list-based component, such as a List or DataGrid, create an item renderer. For information about creating an item renderer, see Custom Spark item renderers.
For the Spark theme, the TextArea control has the following default characteristics:
| Characteristic | Description |
|---|---|
| Default size | 188 pixels wide by 149 pixels high |
| Minimum size | 36 pixels wide and 36 pixels high |
| Maximum size | 10000 pixels wide and 10000 pixels high |
| Default skin class | spark.skins.spark.TextAreaSkin |
For the Mobile theme, the TextArea control has the following default characteristics:
| Characteristic | Description |
|---|---|
| Default skin class | spark.skins.mobile.StageTextAreaSkin |

Descrizione delle proprietà
content | proprietà |
content:Object| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
This property is intended for use in MXML at compile time;
to get or set rich text content at runtime,
use the textFlow property instead. Adobe recommends using
textFlow property to get and set rich text content at runtime,
because it is strongly typed as a TextFlow rather than as an Object.
A TextFlow is the canonical representation
for rich text content in the Text Layout Framework.
The content property is the default property
for TextArea, so that you can write MXML, as the following example shows:
<s:TextArea>Hello <s:span fontWeight="bold">World</s:span></s:TextArea>
In this example, the String and SpanElement that you specify
as the content are used to create a TextFlow.
This property is typed as Object because you can set it to to a String, a FlowElement, or an Array of Strings and FlowElements. In the example above, the content is a 2-element array. The first array element is the String "Hello". The second array element is a SpanElement object with the text "World" in boldface.
No matter how you specify the content, the content is converted to a TextFlow object. When you get the value of this property, you get the resulting TextFlow object.
For the Mobile theme, this is not supported.

Descrizione dei metodi
getFormatOfRange | () | metodo |
public function getFormatOfRange(requestedFormats:Vector.<String> = null, anchorPosition:int = -1, activePosition:int = -1):flashx.textLayout.formats:TextLayoutFormat| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
Returns a TextLayoutFormat object specifying the computed formats for the specified range of characters.
If a format is not consistently set across the entire range,
its value will be undefined.
You can specify a Vector of Strings containing the names of the formats that you care about; if you don't, all formats will be computed.
If you don't specify a range, the selected range is used.
Parametri
requestedFormats:Vector.<String> (default = null)null to request all formats.
| |
anchorPosition:int (default = -1) | |
activePosition:int (default = -1) |
flashx.textLayout.formats:TextLayoutFormat — A TextLayoutFormat object.
|
scrollToRange | () | metodo |
public function scrollToRange(anchorPosition:int = 0, activePosition:int):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
Esegue lo scorrimento affinché l'intervallo di testo sia visibile nel contenitore.
Parametri
anchorPosition:int (default = 0) | |
activePosition:int (default = NaN) |
setFormatOfRange | () | metodo |
public function setFormatOfRange(format:flashx.textLayout.formats:TextLayoutFormat, anchorPosition:int = -1, activePosition:int = -1):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
Applies the specified formats to each element in the specified range that correspond to the given format. It applies the character formats to the text in the specified range (no change is made if the specified range is a single point). It applies the paragraph formats to any paragraphs at least partially within the range (or a single paragraph if the range is a single point). It applies the container formats to the container.
The supported formats are those in TextLayoutFormat.
A value of undefined does not get applied.
If you don't specify a range, the selected range is used.
The following example sets the fontSize and color of the selection:
var textLayoutFormat:TextLayoutFormat = new TextLayoutFormat();
textLayoutFormat.fontSize = 12;
textLayoutFormat.color = 0xFF0000;
myRET.setFormatOfRange(textLayoutFormat);
If you use the results of getFormatOfRange() to
specify the format, note that every format in the
TextLayoutFormat has a
computed value, which will be applied to each element that
corresponds to the given format.
If you would like to specify a format to be applied to all the text
it would be better to use setStyle(format, value)
on the component itself.
The following example sets the fontSize and color of all the text:
myRET.setStyle("fontSize", 12);
myRET.setStyle("color", 0xFF0000);
Parametri
format:flashx.textLayout.formats:TextLayoutFormat — The TextLayoutFormat to apply to the selection.
