cocos2d-x 弹出对话框播放视频

参考 http://www.zaojiahua.com/popscene.html 
的cocos2d-x 弹出对话框的实现， 以及 http://www.cnblogs.com/evan-cai/ 
的用Cocos2d-x和libvlc写一个跨平台播放器， 实现的在弹出的窗口中播放视频，播放结束关闭窗口。

弹出窗口是在Pop类中实现的，头文件 Pop.h 代码如下

#ifndef __POP_H__
#define __POP_H__

#include "cocos2d.h"
#include "cocos-ext.h"
using namespace cocos2d;
using namespace cocos2d::extension;
using namespace std;

class Pop:public CCLayer
{
public:
Pop(void);
~Pop(void);

virtual bool init();

static cocos2d::CCScene* scene();

CREATE_FUNC(Pop);

virtual void registerWithTouchDispatcher(void);
void closeButton(CCObject * object);
virtual bool ccTouchBegan(CCTouch* touch, CCEvent* event);
private:

CCSize m_size;

};
#endif

Pop.cpp 代码

#include "Pop.h"
#include "cocos-ext.h"
#include "movieplayer.h"

using namespace cocos2d;

Pop::Pop(void)
{

}
Pop::~Pop()
{
}

CCScene* Pop::scene()
{
CCScene* scene=CCScene::create();
Pop *layer = Pop::create();
scene->addChild(layer);
return scene;
}
bool Pop::init()
{

CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();
CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin();

m_size=visibleSize/2;    ////

if ( !CCLayer::init() )
{
return false;
}

MoviePlayer* pPlayer = MoviePlayer::instance();
pPlayer->setAnchorPoint(ccp(0,0));
pPlayer->setContentSize(m_size);
pPlayer->setPosition(ccp(400,200));
this->addChild(pPlayer);
pPlayer->play("dizhen.flv");

CCMenuItemImage * item= CCMenuItemImage::create("CloseNormal.png", "CloseSelected.png", this,menu_selector(Pop::closeButton));
item->setPosition(ccp(origin.x+pPlayer->getContentSize().width-item->getContentSize().width/2,origin.y+item->getContentSize().height/2));

CCMenu *menu=CCMenu::create(item,NULL);
menu->setTouchPriority(-229);
menu->setPosition(CCPointZero);
pPlayer->addChild(menu);
return true;
}

void Pop::registerWithTouchDispatcher()
{
CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(this, -128, true);
}

void Pop::closeButton(CCObject * object)
{
MoviePlayer* pPlayer = MoviePlayer::instance();
pPlayer->stop();
this->removeFromParentAndCleanup(true);
}

bool Pop::ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
return true;
}

HelloWorldscene.cpp 中调用函数，生成弹出框层

void HelloWorld::menuCallback(cocos2d::CCObject *pSender){

Pop* pop=Pop::create();

this->addChild(pop);

}
