The Font class is used to manage embedded fonts in SWF files. Embedded fonts are represented as a subclass of the Font class. The Font class is currently useful only to find out information about embedded fonts; you cannot alter a font by using this class. You cannot use the Font class to load external fonts, or to create an instance of a Font object by itself. Use the Font class as an abstract base class.

Property Detail

fontName

property

fontName:String [read-only]

Language Version:

ActionScript 3.0

Runtime Versions:

The name of an embedded font.

Implementation
public function get fontName():String

Example ( How to use this example )

The following example shows how you can use an embedded font with the Flash Professional ActionScript 3.0 CheckBox control by setting the textFormat and embedFonts styles. Example provided by ActionScriptExamples.com.

// Requires:
// - A CheckBox control UI component in Flash library.
// - An embedded font in Flash library with linkage class "MyFont" and Export for ActionScript checked.
//
import fl.controls.CheckBox;
 
var embeddedFont:Font = new MyFont();
 
var textFormat:TextFormat = new TextFormat();
textFormat.font = embeddedFont.fontName;
textFormat.size = 24;
 
var checkBox:CheckBox = new CheckBox();
checkBox.setStyle("textFormat", textFormat);
checkBox.setStyle("embedFonts", true);
checkBox.label = "The quick brown fox jumps over the lazy dog.";
checkBox.textField.autoSize = TextFieldAutoSize.LEFT;
checkBox.move(10, 10);
checkBox.validateNow();
addChild(checkBox);

Method Detail

enumerateFonts

()

method

public static function enumerateFonts(enumerateDeviceFonts:Boolean = false):Array

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0, Flash Player 9, Flash Lite 4

Specifies whether to provide a list of the currently available embedded fonts.

Parameters

enumerateDeviceFonts:Boolean (default = false) — Indicates whether you want to limit the list to only the currently available embedded fonts. If this is set to true then a list of all fonts, both device fonts and embedded fonts, is returned. If this is set to false then only a list of embedded fonts is returned.

Returns

Array — A list of available fonts as an array of Font objects.

Example ( How to use this example )

This example first calls the static method Font.enumerateFonts() to get a list of all device and embedded fonts. Then it sorts the resulting Array of Font objects by the fontName property.

Next the example shows how to call the Font.enumerateFonts() method with the enumerateDeviceFonts parameter set to false. The resulting Array only includes embedded Font objects. (If you run this code within an application that does not contain any embedded fonts, the embeddedFonts array will be empty.)

 
import flash.text.Font;

var allFonts:Array = Font.enumerateFonts(true);
allFonts.sortOn("fontName", Array.CASEINSENSITIVE);

var embeddedFonts:Array = Font.enumerateFonts(false);
embeddedFonts.sortOn("fontName", Array.CASEINSENSITIVE);

hasGlyphs

()

method

public function hasGlyphs(str:String):Boolean

Language Version:

Runtime Versions:

Parameters
