AS3中实现全屏的代码

关键就是下面语句

switch(stage.displayState) {
    case "normal":
      stage.displayState = "fullScreen";     
      break;
    case "fullScreen":
    default:
      stage.displayState = "normal";     
      break;
}

可以按自己需求写两个常用as 1、全屏点击方式

package {
    import flash.display.MovieClip;
    import flash.display.Sprite;   
    import flash.events.MouseEvent;
    public class fullmask extends MovieClip {
      private var _Rect:Sprite;     
      public function fullmask(b_width:int,b_height:int) {       
        _Rect = new Sprite();
        _Rect.graphics.beginFill(0xff0000,0);
        _Rect.graphics.drawRect(0, 0, b_width,b_height);
        _Rect.graphics.endFill();
        addChild(_Rect);
        _Rect.buttonMode = true;
        _Rect.addEventListener(MouseEvent.CLICK, clickHandler)       
      }
          private function clickHandler(event:MouseEvent):void {
              switch(stage.displayState) {
                  case "normal":
                      stage.displayState = "fullScreen";     
                      break;
                  case "fullScreen":
                  default:
                      stage.displayState = "normal";     
                      break;
              }

          }
    }
}

2、按钮点击方式

package {
    import flash.display.MovieClip;
    import flash.display.Sprite;   
    import flash.events.MouseEvent;
    import flash.text.TextField;
    import flash.text.TextFieldAutoSize;   
    public class fullbotton extends MovieClip {
      public function fullbotton(b_width:int,b_height:int,f_size:int) {
        var _Rect:Sprite = new Sprite();
        _Rect.graphics.beginFill(0xff0000,1);
        _Rect.graphics.drawRect(0, 0, b_width,b_height);
        _Rect.graphics.endFill();
        addChild(_Rect);
        _Rect.buttonMode = true;
            var t:TextField = new TextField();
        t.htmlText = "<FONT SIZE='"+f_size+"' color='#ffff00' ><b>点击此处切换观看模式(全屏/普通)</b></font>";
        t.autoSize = TextFieldAutoSize.LEFT;
        t.x=30;
        t.y=2;
        _Rect.addChild(t);
        var _Rect1:Sprite = new Sprite();
        _Rect1.graphics.beginFill(0x000000,0);
        _Rect1.graphics.drawRect(0, 0, b_width,b_height);
        _Rect1.graphics.endFill();
        _Rect.addChild(_Rect1);
        _Rect.addEventListener(MouseEvent.CLICK, clickHandler)       
      }
          private function clickHandler(event:MouseEvent):void {
              switch(stage.displayState) {
                  case "normal":
                      stage.displayState = "fullScreen";     
                      break;
                  case "fullScreen":
                  default:
                      stage.displayState = "normal";     
                      break;
              }

          }
    }
}
