**一、UI 框架的使用方法以及常用接口介绍**

**1. Cocos2d-x 使用UI框架的步骤**：  
1)Cocos2d-x 导入Cocos Studio的UI编辑器文件(json)  
2)创建控件：绑定控件、编码创建控件  
3)使用控件做逻辑处理：比如，按钮、listview、scrollview等等控件做响应事件。

注释:  json 文件(由 ui 编辑器导出生成)来初始化一个 ui 系统,ui 系统 同样会清除当前 ui 系统中的控件,并初始化成 json 文件中描述的 ui 控件。

**2.控件绑定**:

这里举个例子，如图：

![Cocos Studio教程GUI使用学习详解 - 第1张  | 游戏开发网-最好的游戏编程开发技术网站！][Cocos Studio_GUI_ - _1_ _ _-]

// equip root from json  
    Layout* equipe_root =dynamic_cast<Layout*>(GUIReader::shareReader()->widgetFromJsonFile("cocosgui/gui_examples/equip_1/equip_1.json"));  
    equipe_root->setTag(EQUIP_LAYOUT_TAG_ROOT);  
    m_pUILayer->addWidget(equipe_root);          
       
    // title layout  
    Layout* title_layout = dynamic_cast<Layout*>(equipe_root->getChildByName("title_panel"));  
    // close button  
    UIButton* close_btn = dynamic_cast<UIButton*>(title_layout->getChildByName("close_button"));  
    close_btn->setVisible(false);

接着就可以使用绑定的控件做事件处理。

注：这里要注意一点是，我使用的网上的样例，因Cocos2d-x引擎版本不同，需要更改下代码，基本思路都是一样的。  
**3.编码创建控件**:  
举个创建层的例子，代码如下:

//UILayer层  
    m_pUiLayer = UILayer::create();  
    addChild(m_pUiLayer);

**二、各个控件的使用方法**

**1.CocoButto**n

1.1  示例

![Cocos Studio教程GUI使用学习详解 - 第2张  | 游戏开发网-最好的游戏编程开发技术网站！][Cocos Studio_GUI_ - _2_ _ _-]  
1.2  实现代码  
HelloWorldScene.cpp

m_pUiLayer = UILayer::create();  
    addChild(m_pUiLayer);  
      
    m_pWidget = dynamic_cast<UILayout*>(GUIReader::shareReader()->widgetFromJsonFile("cocosgui/UITest/UITest.json"));  
       
    //m_pUiLayer->addWidget(m_pWidget);  
    CCSize widgetSize = m_pWidget->getSize();  
       
    //UILabel文字  
    m_pDisplayValueLabel = UILabel::create();  
    m_pDisplayValueLabel->setText("No Event");  
    m_pDisplayValueLabel->setFontName("Marker Felt");  
    m_pDisplayValueLabel->setAnchorPoint(ccp(0.5f, -1));  
    m_pDisplayValueLabel->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 1.5f));  
    m_pDisplayValueLabel->setColor(ccc3(159, 168, 176));  
    m_pUiLayer->addWidget(m_pDisplayValueLabel);  
       
    //按钮  
    UIButton* button = UIButton::create();  
    button->setTouchEnabled(true);  
    button->setScale9Enabled(true);//是否支持九宫  
    button->loadTextures("cocosgui/animationbuttonnormal.png", "cocosgui/animationbuttonpressed.png", "");  
    button->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 2.0f));  
    button->addTouchEventListener(this, toucheventselector(HelloWorld::touchEvent));  
       
    m_pUiLayer->addWidget(button);

点击事件

void HelloWorld::touchEvent(CCObject *pSender, TouchEventType type)  
    {  
        //按下、移动、结束、取消  
        switch (type)  
        {  
            case TOUCH_EVENT_BEGAN:  
                m_pDisplayValueLabel->setText(CCString::createWithFormat("Touch Down")->getCString());  
                break;  
                   
            case TOUCH_EVENT_MOVED:  
                m_pDisplayValueLabel->setText(CCString::createWithFormat("Touch Move")->getCString());  
                break;  
                   
            case TOUCH_EVENT_ENDED:  
                m_pDisplayValueLabel->setText(CCString::createWithFormat("Touch Up")->getCString());  
                break;  
                   
            case TOUCH_EVENT_CANCELED:  
                m_pDisplayValueLabel->setText(CCString::createWithFormat("Touch Cancelled")->getCString());  
                break;  
                   
            default:  
                break;  
        }  
    }

**2.UICheckBox**

2.1 示例

![Cocos Studio教程GUI使用学习详解 - 第3张  | 游戏开发网-最好的游戏编程开发技术网站！][Cocos Studio_GUI_ - _3_ _ _-]

2.2  代码

//单选按钮  
    UICheckBox* checkBox = UICheckBox::create();  
    checkBox->setTouchEnabled(true);  
    checkBox->loadTextures("cocosgui/check_box_normal.png",  
                           "cocosgui/check_box_normal_press.png",  
                           "cocosgui/check_box_active.png",  
                           "cocosgui/check_box_normal_disable.png",  
                           "cocosgui/check_box_active_disable.png");  
    checkBox->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 2.0f));  
    checkBox->addEventListenerCheckBox(this, checkboxselectedeventselector(HelloWorld::selectedStateEvent));  
    m_pUiLayer->addWidget(checkBox);

响应事件

void HelloWorld::selectedStateEvent(CCObject* pSender, CheckBoxEventType type)  
    {  
        switch (type)  
        {  
            case CHECKBOX_STATE_EVENT_UNSELECTED://取消  
                m_pDisplayValueLabel->setText(CCString::createWithFormat("Unselected")->getCString());  
                break;  
                   
            case CHECKBOX_STATE_EVENT_SELECTED: //选中  
                m_pDisplayValueLabel->setText(CCString::createWithFormat("Selected")->getCString());  
                break;  
                   
            default:  
                break;  
        }  
       
    }

**3.CocoImageView**

3.1  示例

![Cocos Studio教程GUI使用学习详解 - 第4张  | 游戏开发网-最好的游戏编程开发技术网站！][Cocos Studio_GUI_ - _4_ _ _-]

3.2  代码:

UIImageView* imageView = UIImageView::create();  
    //imageView->setScale9Enabled(true);   //是否支持九宫  
    imageView->loadTexture("cocosgui/ccicon.png");  
    imageView->setSize(CCSizeMake(200, 85));  
    imageView->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 2.0f + imageView->getSize().height / 4.0f));  
    m_pUiLayer->addWidget(imageView);

**4.Label**

4.1 标签类型  
CocoLabel 是文本标签,通常用语表示一行文字。

CocoTextArea 是文本区,用于显示文本,于 CocoLabel 不同的是,label 只能 显示一行文 字,而 CocoTextArea 可以将文字显示在一个区域内,并可以换行。

CCLabelBMFont  是文字渲染标签类，相当于每次改变只改变了图片坐标，而CCLabelTTF要重新渲染.这个类使用之前，需要添加好字体文件，包括一个图片文件 (\*\*.png) 和一个 字体坐标文件 （\*\*.fnt）。

4.2  示例

![Cocos Studio教程GUI使用学习详解 - 第5张  | 游戏开发网-最好的游戏编程开发技术网站！][Cocos Studio_GUI_ - _5_ _ _-]

//UILabel文字  
    m_pDisplayValueLabel = UILabel::create();  
    m_pDisplayValueLabel->setText("No Event");  
    m_pDisplayValueLabel->setFontName("Marker Felt");  
    m_pDisplayValueLabel->setAnchorPoint(ccp(0.5f, -1));  
    m_pDisplayValueLabel->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 1.5f));  
    m_pDisplayValueLabel->setColor(ccc3(159, 168, 176));  
    m_pUiLayer->addWidget(m_pDisplayValueLabel);  
       
    //LabelAtlas示例  
    UILabelAtlas* labelAtlas = UILabelAtlas::create();  
    labelAtlas->setProperty("0987654321", "cocosgui/labelatlas.png", 17, 22, "0");  
    labelAtlas->setPosition(ccp((widgetSize.width) / 2, widgetSize.height / 2.0f));  
    m_pUiLayer->addWidget(labelAtlas);  
     
    //labelBMFont示例  
    UILabelBMFont* labelBMFont = UILabelBMFont::create();  
    labelBMFont->setFntFile("cocosgui/bitmapFontTest2.fnt");  
    labelBMFont->setText("BMFont");  
    labelBMFont->setPosition(ccp(widgetSize.width / 2, widgetSize.height / 4.0f + labelBMFont->getSize().height / 8.0f));  
    m_pUiLayer->addWidget(labelBMFont);

**5.滚动条**

5.1  示例

![Cocos Studio教程GUI使用学习详解 - 第6张  | 游戏开发网-最好的游戏编程开发技术网站！][Cocos Studio_GUI_ - _6_ _ _-]

5.2  代码:

//滑动条  
    UISlider* slider = UISlider::create();  
    slider->setTouchEnabled(true);  
    slider->loadBarTexture("cocosgui/sliderTrack2.png");  
    slider->loadSlidBallTextures("cocosgui/sliderThumb.png", "cocosgui/sliderThumb.png", "");  
    slider->loadProgressBarTexture("cocosgui/slider_bar_active_9patch.png");  
    slider->setScale9Enabled(true);  //是否支持九宫  
    slider->setCapInsets(CCRectMake(0, 0, 0, 0));  
    slider->setSize(CCSizeMake(250, 10));  
    slider->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 2.0f));  
    //        slider->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 2.0f + slider->getSize().height * 2));  
    slider->addEventListenerSlider(this, sliderpercentchangedselector(HelloWorld::sliderEvent));  
    m_pUiLayer->addWidget(slider);

处理事件

void HelloWorld::sliderEvent(CCObject *pSender, SliderEventType type)  
    {  
        switch (type)  
        {  
            case ::cocos2d::gui::SLIDER_PERCENTCHANGED:  
            {  
                UISlider* slider = dynamic_cast<UISlider*>(pSender);  
                int percent = slider->getPercent();  
                 m_pDisplayValueLabel->setText(CCString::createWithFormat("Percent %d", percent)->getCString());        }  
                break;  
                   
            default:  
                break;  
        }  
    }

scheduleUpdate();  
    UILoadingBar* loadingBar = UILoadingBar::create();  
    loadingBar->setName("LoadingBar");  
    loadingBar->loadTexture("cocosgui/sliderProgress.png");  
    loadingBar->setPercent(0);  
       
    //LoadingBarTypeLeft 从左向右,LoadingBarTypeRight  从右向左  
    loadingBar->setDirection(LoadingBarTypeRight);  
    loadingBar->setPosition(ccp(widgetSize.width / 2.0f, widgetSize.height / 2.0f + loadingBar->getSize().height / 4.0f));  
    m_pUiLayer->addWidget(loadingBar);

    {  
        m_nCount++;  
        if (m_nCount > 100)  
        {  
            //unscheduleUpdate();  
            m_nCount = 0;  
        }  
           
        UILoadingBar* loadingBar = dynamic_cast<UILoadingBar*>(m_pUiLayer->getWidgetByName("LoadingBar"));

listView->setDirection(SCROLLVIEW\_DIR\_BOTH);     //滚动方向

        imageView->setScale9Enabled(true);  
        imageView->loadTexture("cocosgui/scrollviewbg.png");  
        imageView->setSize(CCSizeMake(240, 130));  
        imageView->setPosition(ccp(layout->getSize().width / 2, layout->getSize().height / 2));  
        layout->addChild(imageView);  
           
        UILabel* label = UILabel::create();  
        label->setText(CCString::createWithFormat("page %d", (i + 1))->getCString());  
        label->setFontName("Marker Felt");  
        label->setFontSize(30);  
        label->setColor(ccc3(192, 192, 192));  
        label->setPosition(ccp(layout->getSize().width / 2, layout->getSize().height / 2));  
        layout->addChild(label);  
           
        pageView->addPage(layout);  
    }  
    pageView->addEventListenerPageView(this, pagevieweventselector(HelloWorld::pageViewEvent));  
       
    m_pUiLayer->addWidget(pageView);

事件响应：

void HelloWorld::pageViewEvent(CCObject *pSender, PageViewEventType type)  
    {  
        switch (type)  
        {  
            case PAGEVIEW_EVENT_TURNING:  
            {  
                UIPageView* pageView = dynamic_cast<UIPageView*>(pSender);  
                   
                m_pDisplayValueLabel->setText(CCString::createWithFormat("page = %d", pageView->getCurPageIndex() + 1)->getCString());  
            }  
                break;  
                   
            default:  
                break;  
        }  
    }

本人参考cocos2d-x 2.2.2 testcpp的例子实现，有关绑定控件实现也是类似的。
