The UITextFormat class represents character formatting information for the UITextField class. The UITextField class defines the component used by many Flex composite components to display text.

The UITextFormat class extends the flash.text.TextFormat class to add the text measurement methods measureText() and measureHTMLText() and to add properties for controlling the advanced anti-aliasing of fonts.

Property Detail

antiAliasType

property

public var antiAliasType:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Defines the anti-aliasing setting for the UITextField class. The possible values are "normal" (flash.text.AntiAliasType.NORMAL) and "advanced" (flash.text.AntiAliasType.ADVANCED).

The default value is "advanced", which enables advanced anti-aliasing for the embedded font. Set this property to "normal" to disable the advanced anti-aliasing.

This property has no effect for system fonts.

This property applies to all the text in a UITextField object; you cannot apply it to some characters and not others.

The default value is "advanced".

The directionality of the text.

The allowed values are "ltr" for left-to-right text, as in Latin-style scripts, and "rtl" for right-to-left text, as in Arabic and Hebrew.

FTE and TLF use this value in their bidirectional text layout algorithm, which maps Unicode character order to glyph order.

Note: This style only applies when this UITextFormat is used with a UIFTETextField rather than a UITextField.

The default value is null.

gridFitType

property

public var gridFitType:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Defines the grid-fitting setting for the UITextField class. The possible values are "none" (flash.text.GridFitType.NONE), "pixel" (flash.text.GridFitType.PIXEL), and "subpixel" (flash.text.GridFitType.SUBPIXEL).

This property only applies when you are using an embedded font and the fontAntiAliasType property is set to "advanced".

This property has no effect for system fonts.

This property applies to all the text in a UITextField object; you cannot apply it to some characters and not others.

The default value is "pixel".
