ContentElement is an abstract base class; therefore, you cannot instantiate ContentElement directly.
Invoking new ContentElement() throws an ArgumentError exception.
You can assign a ContentElement element to exactly one GroupElement or to the content property of exactly one text
block.

elementFormat | property |
elementFormat:ElementFormat| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5, Flash Lite 4 |
The ElementFormat object used for the element.
The default value is null.
When the elementFormat property is set, the ElementFormat object provided is locked: its locked
property is set to true. A locked ElementFormat cannot be modified.

eventMirror | property |
eventMirror:EventDispatcher| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5, Flash Lite 4 |
The EventDispatcher object that receives copies of every
event dispatched to valid text lines based on this content element.
The specified object can be used to set up listeners for a text link or other
interactive piece of text, as it can be difficult to determine at runtime which parts
of lines have resulted from particular content elements.
You can also use listeners to apply decorations such as underlines, the metrics of which
you cannot determine until after the text is laid out.
The default value is null, which means no mirrored events are dispatched.
Event mirrors manifest themselves in text lines as instances of the TextLineMirrorRegion
class. Depending on bidirectional processing and line breaking, one or more mirror regions can be produced.
The default value is null.

groupElement:GroupElement [read-only] | Language Version: | ActionScript 3.0 |

rawText | property |
rawText:String [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5, Flash Lite 4 |
A copy of the text in the element, including any U+FDEF characters. The Unicode character, U+FDEF, marks the location of a graphic element in the String.
Implementation

textBlock | property |
textBlock:flash.text.engine:TextBlock [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5, Flash Lite 4 |
The TextBlock to which this element belongs.
The default value is null.

textBlockBeginIndex | property |
textBlockBeginIndex:int [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5, Flash Lite 4 |
The index in the text block of the first character of this element. This value is not cached; it is calculated whenever this method is called.
The default value is -1.
Implementation
public function get textBlockBeginIndex():inttextRotation | property |
textRotation:String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5, Flash Lite 4 |
The rotation to apply to the element as a unit. Use TextRotation
constants for this property.
The default value is TextRotation.ROTATE_0.
The final rotation of any glyph is the sum of ElementFormat.textRotation, ContentElement.textRotation, and TextBlock.lineRotation.
ContentElement.textRotation is used to create a short run of text whose
rotation differs from the containing line. TCY runs in Japanese text are an example. TCY stands for Tate-Chu-Yoko
and refers to a little horizontal run of text (usually a number) in some vertical Japanese text.
To create a Paragraph of vertical Japanese text containing a TCY run, do the following:
- Set
TextBlock.lineRotation=TextRotation.ROTATE_90 - Set
TextBlock.contentto a GroupElement, consisting of three TextElement objects. The first of these elements is the Japanese text before the TCY run, the second is the Latin text of the TCY run, and the third is the Japanese text after the TCY run. - Set the
textRotationproperty of the TCY TextElement toTextRotation.ROTATE_270. The TCY text element rotates as a unit. It starts with a 90 degree rotation inherited from the line. Adding another 270 degrees takes it around to horizontal.
Rotated content elements cannot be nested. In any hierarchy of content elements, no matter how complex,
only one content element can have its textRotation property set. The following methods and property setters throw an
argument error if nested rotations are detected:
ContentElement.textRotationGroupElement.setElementsGroupElement.replaceElements
To set values for this property, use the following string values:
| String value | Description |
|---|---|
TextRotation.ROTATE_0 | Element is not rotated. |
TextRotation.ROTATE_90 | Element is rotated 90 degrees clockwise. |
TextRotation.ROTATE_180 | Element is rotated 180 degrees. |
TextRotation.ROTATE_270 | Element is rotated 270 degrees clockwise. |
TextRotation.AUTO | Not supported. |
Implementation
public function get textRotation():String public function set textRotation(value:String):voidThrows
ArgumentError — If set to any value that is not a member of TextRotation.
| |
ArgumentError — If set to TextRotation.AUTO.
| |
ArgumentError — If the operation would result in nested rotations within a GroupElement.
