Delphi中的'inherited'关键字是一个强大工具,它允许子类调用并扩展其祖先类的成员函数。当你在子类中使用'inherited'时,实际上是让子类的函数在执行时默认调用相应于该名称的祖先类函数。如果函数没有参数,就像祖先类的函数Create(AName:string)一样,那么子类直接使用'inherited Create(AName)'调用即可...
Delphi 系统[25]关键字和保留字 override、overload、reintroduce、inherited 1、定义: override :指示子类覆写父类的一个 virtual 或 dynamic 方法。覆盖时必须沿用被覆盖方法的声明,并且不允许修改原方法的参数和返回类型。 overload :指示重载一个同名函数、过程或方法。重载的同名方法时,必须具备“参数、类型或...
inherited就是调用祖先类的函数,如果不带参数就是默认调用同名函数 如果带参数则表明子类中的函数个数可能比祖先类要多取其中的几个参数传过去 例如 祖先类有个函数 Create(AName:string);子类有个函数 Create(AName:string;AComponent:TObject);override;那么子类的Create函数内就可以这样调用祖先类:p...

我知道,当我编写一个新对象的constructor时,首先我必须调用inherited Create,以便创建对象的实例,然后进行初始化。但是在这里,如果我调用inherited,线程将在没有初始化参数的情况下启动。我试着最后打电话给inherited,它看起来很有效(我没有收到任何访 浏览3提问于2020-09-18得票数 2 回答已采纳 1回答 在Delphi...
