Flash右键单击的动作与左键单击不同

Question

我刚刚更新到flash player 11.2,它允许监听MouseEvent.RIGHT_MOUSE_UP和MouseEvent.RIGHT_MOUSE_DOWN.

我遇到的问题是这些事件的行为与其MOUSE_UP/MOUSE_DOWN对应物的行为不同.具体来说,无论鼠标在哪里,都会启动MOUSE_UP事件.这允许在Flash窗口外拖动,并且每当用户点击flash播放器时仍然具有完整的down - > up事件循环.

但是,RIGHT_MOUSE_UP/DOWN似乎不是这种情况.当我右键单击播放器并在播放器外部释放时,我没有得到RIGHT_MOUSE_UP事件,这意味着可以在不接收UP事件的情况下接收多个RIGHT_MOUSE_DOWN事件.

是否有一个已知的解决方法或是否有一个我必须设置的选项？

编辑:

这是一个代码示例:

stage.addEventListener(MouseEvent.MOUSE_UP,         onMouseUp);
stage.addEventListener(MouseEvent.MOUSE_DOWN,       onMouseDown);
stage.addeventListener(MouseEvent.RIGHT_MOUSE_UP,   onRightMouseUp);
stage.addeventListener(MouseEvent.RIGHT_MOUSE_DOWN, onRightMouseDown);

//...
//all callback function follow a similar format as :
private function onMouseUp(e : MouseEvent) : void
{
    leftClick_ = false;//signaling that leftClick is not pressed
}

您可以监听鼠标何时离开舞台，这可以充当RIGHT_CLICK_UP事件的代理。

package 
{
    //Imports
    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.Event;
    import flash.events.MouseEvent;

    //Class
    [SWF(width="640", height="480", frameRate="60", backgroundColor="0x555555")]
    public class RightClickTest extends Sprite
    {
        //Constructor
        public function RightClickTest()
        {
            stage.scaleMode = StageScaleMode.NO_SCALE;
            stage.align = StageAlign.TOP_LEFT;

            addEventListener(Event.ADDED_TO_STAGE, init);
        }

        //Initialize
        private function init(event:Event):void
        {
            removeEventListener(Event.ADDED_TO_STAGE, init);

            stage.addEventListener(MouseEvent.RIGHT_MOUSE_DOWN, mouseRightClickEventHandler);
            stage.addEventListener(MouseEvent.RIGHT_MOUSE_UP, mouseRightClickEventHandler);
            stage.addEventListener(Event.MOUSE_LEAVE, mouseLeaveEventHandler);
        }

        //Mouse Right Click Event Handler
        private function mouseRightClickEventHandler(event:MouseEvent):void
        {
            switch (event.type)
            {
                case MouseEvent.RIGHT_MOUSE_DOWN:   trace("Right Mouse Down");
                                                    break;

                case MouseEvent.RIGHT_MOUSE_UP:     trace("Right Mouse Up");
            }
        }

        //Mouse Leave Event Handler
        private function mouseLeaveEventHandler(event:Event):void
        {
            trace("Mouse Leave");
        }
    }
}

但是，如果您试图避免允许用户显示多个右键单击上下文菜单（或类似的内容），您可以在代码中实现一个简单的检查，以在显示新菜单之前先隐藏可见的右键单击上下文菜单。
