代码格式

头文件的格式：

　　开头两行与结尾一行是防止文件重复包含的,也仅仅是防止文件被重复包含,是无法防止变量被重复定义的,

　　之后是在此头文件下包含的其他头文件,

　　假如使用了前向声明,那么在头文件的下方紧接着就可以 class这些类了,

　　如果不打算在qml中调用C++的枚举的话,枚举可以接着前向声明写,

　　这里是正式对类的定义了,一般的类如果你想使用qt的信号槽功能的话那么需要让类直接继承或间接继承Q_OBJECT类,　

　　不算头文件，在类的声明中将Q_ENUMS Q_FLAGS的使用放在最前面(Q_ENUMS在这里声明)，Q_PROPERTY的定义紧跟其后，

　　再然后是构造函数与析构函数的修饰符及其定义,修饰符之前不加任何空白符,

　　接着是成员函数及成员变量的定义,public 成员函数，信号，槽函数，protect的成员函数，槽函数，成员变量，private的成员函数，槽函数，成员变量

　　一般的先包含头文件,之后是一些const型变量的定义,接着是构造函数以及析构函数的实现
