package
{
    import flash.display.Sprite;
    import flash.text.TextField;
    import flash.text.TextFieldType;
    import flash.text.TextFormat;        //文字格式类
    
    public class Main extends Sprite
    {    
        public function Main():void
        {
            var format:TextFormat = new TextFormat();
            format.bold = true;
            format.color = 0xff0000;
            format.size = 40;
            format.underline = true;                //带下划线
            format.url = "http://www.baidu.com";
            format.target = "_blank";
            
            var txt:TextField = new TextField();
            txt.text = "AS3开发";
            txt.setTextFormat(format);                //格式绑定下
            txt.width = 300;
            txt.height = 300;
            
            this.addChild(txt);
        }
