实现双击鼠标事件功能

实现双击鼠标事件功能

用其它事件都可以的,把MouseEvent.DOUBLE_CLICK改成MouseEvent.MOUSE_WHEEL也可以触发,双击也可以触发.

复制内容到剪贴板代码:
package
{
    import flash.display.Sprite;
    import flash.events.MouseEvent;
   
    public class DrawApp extends Sprite
    {
        public function DrawApp()
        {
            init();
           
        }
        private function init():void{
            stage.doubleClickEnabled = true;
            stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDownHandler);
            stage.addEventListener(MouseEvent.MOUSE_UP, onMouseUpHandler);
            stage.addEventListener(MouseEvent.DOUBLE_CLICK, onMouseDCHandler);
        }
       
       
        private function onMouseDownHandler(e:MouseEvent):void{
            graphics.moveTo(mouseX, mouseY);
            stage.addEventListener(MouseEvent.MOUSE_MOVE, onMouseMoveHandler);
        }
       
        private function onMouseUpHandler(e:MouseEvent):void{
            stage.removeEventListener(MouseEvent.MOUSE_MOVE, onMouseMoveHandler);
        }
       
        private function onMouseMoveHandler(e:MouseEvent):void{
            graphics.lineTo(mouseX, mouseY);
        }
       
        private function onMouseDCHandler(e:MouseEvent):void{
            graphics.lineStyle(1);
            graphics.clear();
        }
    }
}
