LinkBut​​ton 鼠标事件问题

Question

你好 我有 2 个 mxml 文件，其中 ....

CustComp.mxml

<mx:LinkButton id="linkbutton" label="ClickMe"  click="onLinkClicked()" mouseOver="onMouseOver()" mouseOut="onMouseOut()" />

private function onLinkClicked():void{
dispatchEvent(new CustomEvent("onClick");}
private function onMouseOver(event:CustomEvent):void{
dispatchEvent(new CustomEvent("onMouseOver");}
private function onMouseOut(event:CustomEvent):void{
dispatchEvent(new CustomEvent("onMouseOut");}

Main.mxml

var customComp:CustComp = new CustComp();
customComp.addEventListener(CustomEvent.MOUSE_CLICK1,onLinkClicked111);
customComp.addEventListener(CustomEvent.MOUSE_OVER1,onMouseOver111);
customComp.addEventListener(CustomEvent.MOUSE_OUT1,onMouseOut111);

private function onLinkClicked111(event:CustomEvent):void{
trace("click event");}
private function onMouseOver111(event:CustomEvent):void{
trace("mouse over event");}
private function onMouseOut111(event:CustomEvent):void{
trace("mouse out event");}

当我将鼠标悬停在组件中的链接按钮上或将鼠标移开时，事件将被分派到 main.mxml，并且相应的函数将被完美调用。但是当我单击按钮时， onLinkClicked111() 函数会被调用一次，并且 onMouseOut111() 和 onMouseOver111() 会被重复调用，直到我使光标从链接按钮上移开。 请帮助我，我应该做什么来确保当我单击时，只调用 onLinkclicked111() 函数而不是 mouseOver111() 或 mouseOut111()

不确定您真正需要什么，但这是简化的示例

                addEventListener("onClick", onClickHandler);

                addEventListener("onMouseOut", onMouseOutHandler);
            }

            }


            private function onLinkClicked():void
