setNotificationNode 有没有简单的办法实现正确的点击事件？？

测试场景
Scene *scene = Scene::create();
Director::getInstance()->runWithScene(scene);
Button* btn = Button::create("res/Image/Common/Frame23.png");
btn->addTouchEventListener([=](Ref* sender, Widget::TouchEventType type){
if (type == Widget::TouchEventType::ENDED){
CCLOG("22222");
}
});
btn->setPosition(Vec2(320,800));
scene->addChild(btn);

Layer* l = Layer::create();
Director::getInstance()->setNotificationNode(l);

Widget* widget= (Widget*)CSLoader::createNode("res/Image/Dialog/NetConfirmDialog.csb");
widget->setContentSize(Director::getInstance()->getWinSize());
Helper::doLayout(widget);
l->addChild(widget);


Button* btn2 = (Button*)Helper::seekWidgetByName(widget,"confirmBtn");
btn2->addTouchEventListener([=](Ref* sender, Widget::TouchEventType type){
    if (type == Widget::TouchEventType::ENDED){
        CCLOG("1111111");
    }
});

btn2->setTouchPriority(-2);
Helper::seekWidgetByName(widget,"bgPanel")->setTouchPriority(-1);
Helper::seekWidgetByName(widget,"bgPanel")->addTouchEventListener([=](Ref* sender, Widget::TouchEventType type){
    if (type == Widget::TouchEventType::ENDED){
        CCLOG("33333");
    }
});

修改Widget:
void Widget::setTouchPriority(int priority)
{
if(_touchListener){
eventDispatcher->removeEventListener(touchListener);
eventDispatcher->addEventListenerWithFixedPriority(touchListener, priority);

}

}

bool Widget::onTouchBegan(Touch *touch, Event *unusedEvent)
{
_hitted = false;
if (isVisible() && isEnabled() && isAncestorsEnabled() && isAncestorsVisible(this) )
{
_touchBeganPosition = touch->getLocation();
auto camera = Camera::getVisitingCamera();
if(camera == nullptr){
camera = Director::getInstance()->getRunningScene()->getDefaultCamera();
}
if(hitTest(_touchBeganPosition, camera, nullptr))
{
if (isClippingParentContainsPoint(_touchBeganPosition)) {
_hittedByCamera = camera;
_hitted = true;
}
}
}
if (!_hitted)
{
return false;
}
setHighlighted(true);

/*
 * Propagate touch events to its parents
 */
if (_propagateTouchEvents)
{
    this->propagateTouchEvent(TouchEventType::BEGAN, this, touch);
}

pushDownEvent();
return true;

}

这样做虽然是可以让NotificationNode上的按钮触发点击，但是能不能提供一个更方便的NotificationNode 让人使用
