获取类的名称,注意,若某个 QObject 的子类未启动元对象系统(即未使用 Q_OBJECT宏),则该函数将获取与该类最接近的启动了元对象系统的父类的名称,而不再返回该类的名称,因此建议所有的 QObject 子类都使用 Q_OBJECT 宏。 const QMetaObject* superClass() const; 1. 返回父类的元对象,若没有这样的对象则返...

它是该函数的一个重新实现,并且在Circle实例上通过Shape引用或者指针调用draw()时,就会以多态的形式调用该函数。C++不像C#那样有override关键字。而且C++也没有能够指向基类的super或者base关键字。如果需要调用一个函数的基本实现,则可以在这个函数的名字前加上一个由基类的名字和‘::’操作符构成的前缀。例如:...
