cocos2dx cceditbox使用注意事项

基本用法见testcpp .cocos2d-x版本为2.1.4

.h文件

 

注意：这里继承于CCEditBoxDelegate代理，不直接继承于CCEditBox，而是将CCEditBox作为组合使用。

并将本身的Layer作为被代理对象，重载CCEditBoxDelegate接口。

CCEditBox的默认字体色是白色，若是用白色的底框则看不到输入内容，所有务必检查字体颜色

CCeditBox在安卓下的坐标与cocos2dx其他控件一致，锚点也生效，win下的效果与安卓上效果一致。

 

class EditBoxTest : public cocos2d::CCLayer, public cocos2d::extension::CCEditBoxDelegate
{
public:
    EditBoxTest();
    virtual ~EditBoxTest();
    void toExtensionsMainLayer(cocos2d::CCObject *sender);
   
    virtual void editBoxEditingDidBegin(cocos2d::extension::CCEditBox* editBox);
    virtual void editBoxEditingDidEnd(cocos2d::extension::CCEditBox* editBox);
    virtual void editBoxTextChanged(cocos2d::extension::CCEditBox* editBox, const std::string& text);
    virtual void editBoxReturn(cocos2d::extension::CCEditBox* editBox);
private:
    cocos2d::CCLabelTTF* m_pTTFShowEditReturn;
    cocos2d::extension::CCEditBox* m_pEditName;
    cocos2d::extension::CCEditBox* m_pEditPassword;
    cocos2d::extension::CCEditBox* m_pEditEmail;
};
