    public function set beginIndex(value:int):void

bullet

property 
bullet:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Whether the text in the range is in a bulleted list. If only part of the range is in a bulleted list, this value is false.

    public function set bullet(value:Boolean):void

color

property 
color:Object

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Color of the text in the range. You can set this value using any valid color identifier. The property returns the value as a numeric value. If the range has multiple colors, this value is null.



Implementation
    public function get color():Object
    public function set color(value:Object):void

endIndex

property 
endIndex:int

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Zero-based index in the control's text field of the point immediately after the last character in the range; equivalent to the One-based index of the last character. If the fifth character in the text is the last character in the range, this property has a value of 5.



Implementation
    public function get endIndex():int
    public function set endIndex(value:int):void

fontFamily

property 
fontFamily:String

Language Version: ActionScript 3.0
Product Version: Flex 3

    public function set fontFamily(value:String):void

fontSize

property 
fontSize:int

Point size of the text in the range. If the range has multiple sizes, this value is 0.

fontStyle

property 
fontStyle:String

Language Version: ActionScript 3.0

Style of the font in the range, as "italic" or "normal". Setting the property to any other string results in normal style. If the range has multiple styles, this value is null.



Implementation
    public function get fontStyle():String
    public function set fontStyle(value:String):void

fontWeight

property 
fontWeight:String

Language Version: ActionScript 3.0
Product Version: Flex 3

htmlText

property 
htmlText:String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Contents of the range in the form of HTML text. This property returns all HTML markup for the range, including markup for formatting that is applied by Flex, not just HTML that you specify in using an htmlText property. This property is, therefore, a full HTML representation of the text as it appears in the control.



Implementation
    public function get htmlText():String
    public function set htmlText(value:String):void

kerning

property 
kerning:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

A Boolean value that indicates whether kerning is enabled (true) or disabled (false). Kerning adjusts the pixels between certain character pairs to improve readability, and should be used only when necessary, such as with headings in large fonts. Kerning is supported for embedded fonts only. Certain fonts, such as Verdana, and monospaced fonts, such as Courier New, do not support kerning.

The default value is false.



Implementation
    public function get kerning():Boolean
    public function set kerning(value:Boolean):void

letterSpacing

property 
letterSpacing:Number

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The number of additional pixels to appear between each character. A positive value increases the character spacing beyond the normal spacing, while a negative value decreases it.

The default value is 0.



Implementation
    public function get letterSpacing():Number
    public function set letterSpacing(value:Number):void

modifiesSelection

property 
modifiesSelection:Boolean  [read-only]

owner:UIComponent

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The control that contains the text. The owner control must have a textField property, or, as is the case of the RichTextEditor control, a textArea property. The owner of the text in a RichTextEditor control is the RichTextEditor control, not its TextArea subcontrol. Initially set by the constructor.



Implementation
    public function get owner():UIComponent
    public function set owner(value:UIComponent):void

text

property 
text:String

Language Version: ActionScript 3.0

    public function set text(value:String):void

textAlign

property 
textAlign:String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Alignment of the text in the range. The flash.text.TextFormatAlign constants specify the valid values. Setting this property to any other value has no effect. If the range has multiple alignments, this value is null.



Implementation
    public function get textAlign():String
    public function set textAlign(value:String):void

url

property 
url:String

Language Version: ActionScript 3.0

    public function get url():String
    public function set url(value:String):void
Constructor Detail

TextRange

()Constructor
public function TextRange(owner:UIComponent, modifiesSelection:Boolean = false, beginIndex:int = -1, endIndex:int = -1)

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Create a new TextRange Object that represents a subset of the contents of a text control, including the formatting information.

Parameters
owner:UIComponent — The control that contains the text. The control must have a textField property, or, as is the case of the RichTextEditor control, a textArea property.
 
modifiesSelection:Boolean (default = false) — Whether to select the text in the range. If you set this parameter to true and do not specify a begin or end index that corresponds to text in the control, Flex uses the begin or end index of the current text selection. If this parameter is true, you omit the beginIndex and endIndex parameters, and there is no selection, the TextRange object is empty.
 
beginIndex:int (default = -1) — Zero-based index of the first character in the range. If the modifiesSelection parameter is false and you omit this parameter or specify a negative value, the range starts with the first text character.
 
endIndex:int (default = -1) — Zero-based index of the position after the last character in the range. If the modifiesSelection parameter is false and you omit this parameter, specify a negative value, or specify a value past the end of the text, the range ends with the last text character.
