Constructor:构造函数。 三、成员函数 1、QMetaMethod::Access access() 返回此方法的访问级别。 2、【static】template <typename PointerToMemberFunction> QMetaMethod fromSignal(PointerToMemberFunction signal) 返回与给定信号对应的元方法,如果信号不是类的信号,则返回无效的 QMetaMethod。 QMetaMethod destroyedS...
constructor()和constructorCount()提供类的元构造函数信息。 indexOfConstructor()、indexOfMethod()、indexOfEnumerator()和indexOfProperty()等索引函数将构造函数、成员函数、枚举器或属性名称映射到元对象中的索引。例如,在将信号连接到槽时,Qt在内部使用indexOfMethod()。 类还可以具有其他类信息的名称-值对列表,...
