Using the Flash Text Engine
package
{
import flash.text.engine.*;
import flash.display.Sprite;
}
public class HelloWorldExample extends Sprite
{
public function HelloWorldExample()
{
var str = "Hello World! This is Flash Text Engine!";
var format:ElementFormat = new ElementFormat();
var textElement:TextElement = new TextElement(str, format);
var textBlock:TextBlock = new TextBlock();
textBlock.content = textElement;
}
}
var textLine1:TextLine = textBlock.createTextLine(null, 300);
addChild(textLine1);
textLine1.x = 30;
textLine1.y = 30;
The parameters for createTextLine() specify the line from which to begin the new line and the width of the line in
pixels. The line from which to begin the new line is usually the previous line but, in the case of the first line, it is null.
Adding GraphicElement and GroupElement objects
Flash Player 10 and later, Adobe AIR 1.5 and later
You can assign a GraphicElement object to a TextBlock object to display an image or a graphic element. Simply create
an instance of the GraphicElement class from a graphic or an image and assign the instance to the
TextBlock.content property. Create the text line by calling TextBlock.createTextline() as you normally would.
The following example creates two text lines, one with a GraphicElement object and one with a TextElement object.
package
{
import flash.text.engine.*;
import flash.display.Sprite;
import flash.display.Shape;
import flash.display.Graphics;
public class GraphicElementExample extends Sprite
{
public function GraphicElementExample()
{
var str:String = "Beware of Dog!";
var triangle:Shape = new Shape();
triangle.graphics.beginFill(0xFF0000, 1);
triangle.graphics.lineStyle(3);
triangle.graphics.moveTo(30, 0);
triangle.graphics.lineTo(60, 50);
triangle.graphics.lineTo(0, 50);
triangle.graphics.lineTo(30, 0);
triangle.graphics.endFill();
