Property Detail

alignment

property
alignment:*

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The tab alignment for this tab stop.

Legal values are flash.text.engine.TabAlignment.START, flash.text.engine.TabAlignment.CENTER, flash.text.engine.TabAlignment.END, flash.text.engine.TabAlignment.DECIMAL, flashx.textLayout.formats.FormatValue.INHERIT.

Default value is undefined indicating not set.

If undefined during the cascade this property will have a value of START.



Implementation
    public function get alignment():*
    public function set alignment(value:any):void

Throws

decimalAlignmentToken

property 
decimalAlignmentToken:*

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The alignment token to be used if the alignment is DECIMAL.

Default value is undefined indicating not set.

If undefined during the cascade this property will have a value of null.



Implementation

property 
defaultFormat:flashx.textLayout.formats:ITabStopFormat  [read-only]

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Returns a TabStopFormat object with default settings. This function always returns the same object.



Implementation
    public static function get defaultFormat():flashx.textLayout.formats:ITabStopFormat

position

property 
position:*

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The position of the tab stop, in pixels, relative to the start of the line.

Constructor Detail

TabStopFormat

()Constructor
public function TabStopFormat(initialValues:flashx.textLayout.formats:ITabStopFormat = null)

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Creates a new TabStopFormat object. All settings are empty or, optionally, are initialized from the supplied initialValues object.

Parameters
initialValues:flashx.textLayout.formats:ITabStopFormat (default = null) — optional instance from which to copy initial values.

Method Detail

apply

()method
public function apply(incoming:flashx.textLayout.formats:ITabStopFormat):void

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Replaces property values in this TabStopFormat object with the values of properties that are set in the incoming ITabStopFormat instance. Properties that are undefined in the incoming ITabStopFormat instance are not changed in this object.

Parameters

incoming:flashx.textLayout.formats:ITabStopFormat — instance whose property values are applied to this TabStopFormat object.

concat

()method 
public function concat(incoming:flashx.textLayout.formats:ITabStopFormat):void

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Concatenates the values of properties in the incoming ITabStopFormat instance with the values of this TabStopFormat object. In this (the receiving) TabStopFormat object, properties whose values are FormatValue.INHERIT, and inheriting properties whose values are undefined will get new values from the incoming object. Non-inheriting properties whose values are undefined will get their default values. All other property values will remain unmodified.

Parameters

incoming:flashx.textLayout.formats:ITabStopFormat — instance from which values are concatenated.

concatInheritOnly

()method 
public function concatInheritOnly(incoming:flashx.textLayout.formats:ITabStopFormat):void

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Concatenates the values of properties in the incoming ITabStopFormat instance with the values of this TabStopFormat object. In this (the receiving) TabStopFormat object, properties whose values are FormatValue.INHERIT, and inheriting properties whose values are undefined will get new values from the incoming object. All other property values will remain unmodified.

Parameters

incoming:flashx.textLayout.formats:ITabStopFormat — instance from which values are concatenated.

copy

()method 
public function copy(values:flashx.textLayout.formats:ITabStopFormat):void

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Copies TabStopFormat settings from the values ITabStopFormat instance into this TabStopFormat object. If values is null, this TabStopFormat object is initialized with undefined values for all properties.

Parameters

values:flashx.textLayout.formats:ITabStopFormat — optional instance from which to copy values.

isEqual

()method 
public static function isEqual(p1:flashx.textLayout.formats:ITabStopFormat, p2:flashx.textLayout.formats:ITabStopFormat):Boolean

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Compares properties in ITabStopFormat instance p1 with properties in ITabStopFormat instance p2 and returns true if all properties match.

Parameters

p1:flashx.textLayout.formats:ITabStopFormat — instance to compare to p2.
 
p2:flashx.textLayout.formats:ITabStopFormat — instance to compare to p1.

Returns
Boolean — true if all properties match, false otherwise.

removeClashing

()method 
public function removeClashing(incoming:flashx.textLayout.formats:ITabStopFormat):void

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Sets properties in this TabStopFormat object to undefined if they do not match those in the incoming ITabStopFormat instance.

Parameters

incoming:flashx.textLayout.formats:ITabStopFormat — instance against which to compare this TabStopFormat object's property values.

removeMatching

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Sets properties in this TabStopFormat object to undefined if they match those in the incoming ITabStopFormat instance.

Parameters

incoming:flashx.textLayout.formats:ITabStopFormat — instance against which to compare this TabStopFormat object's property values.

TabStopFormat_example.as

This example creates a paragraph that uses an array of three tab stops: a left-aligned tab at 50 pixels, a center-aligned tab at 150 pixels, and a right-aligned tab at 250 pixels.
