CCMenu这是一个抽象的东西，容纳菜单项CCMenuItem的容器

CCMenuItem继承图：

Button::ButtonTest(void)
{
//设置字体大小
CCMenuItemFont::setFontSize( 30 );
//根据名字设置字体
CCMenuItemFont::setFontName("Courier New");
//设置能点击
setTouchEnabled(true);
// Font Item

//参数说明：第一个图片名字，第二参数截图menuitemsprite.png的一个对象(x,y,w,h),说明此处的x,y为图片的坐标喔~

CCSprite* spriteDisabled = CCSprite::create("menuitemsprite.png", CCRectMake(0,23*0,115,23));

//创建一个CCMenuItemSprite，参数：添加三种状态CCSprite,添加item1的节点，注册返回监听
CCMenuItemSprite* item1 = CCMenuItemSprite::create(spriteNormal, spriteSelected, spriteDisabled, this, menu_selector(MenuTestLayer::menuCallback) );

// 创建一个CCMenuItemImage,参数:同上
CCMenuItem* item2 = CCMenuItemImage::create("SendScoreButton.png", "SendScoreButtonPressed.png", this, menu_selector(MenuTestLayer::menuCallback2) );

CCLabelAtlas* labelAtlas = CCLabelAtlas::create("0123456789", "fonts/labelatlas.png", 16, 24, '.');

CCMenuItemLabel* item3 = CCMenuItemLabel::create(labelAtlas, this, menu_selector(MenuTestLayer::menuCallbackDisabled) );
item3->setDisabledColor( ccc3(32,32,64) );//设置不能点击的颜色(一般采用灰色)


// 创建一个CCMenuItemFont

// 创建一个CCMenuItemFont

CCMenuItemFont *item6 = CCMenuItemFont::create("Priority Test", this, menu_selector(MenuTestLayer::menuCallbackPriorityTest));

// 创建一个CCMenuItemFont

//为CCMenuItemFon添加一个颜色循环变化动画....item7也是父类CCNode的子类，自然也可以添加动画啦

//创建CCMenu菜单，其他可认为是菜单项
CCMenu* menu = CCMenu::create( item1, item2, item3, item4, item5, item6, item7, NULL);
menu->alignItemsVertically();//可以理解为设置成垂直排列
//menu->alignItemsHorizontally();//水平排列

// elastic effect
