Delphi 系统[21]关键字和保留字 constructor、destructor、property - 构造函数,析构函数、属性 1、定义: constructor :声明或定义一个构造函数,可以用于类类型、对象类型、结构类型。 结构类型不允许定义无参数的构造函数。当类被实例化时, 首先调用此函数 ,构造函数一般用Create表示, Create
千万别在Destroy里释放用Create(AOwner)建立起来的控件(Delphi会自动释放, 而且 你不知道在你的Destroy被Delphi调用时该控件是否已经被Delphi释放掉了, 除非你 override了Notification方法, 只有在那里面才能得知哪些控件会在调用你的Destroy前 就被释放掉了).
TestClass = class(TObiect)publiicConstructor Create ;destructor Free;procedure Add;end;调用的时候创建一个对象去调用类方法。如：varAAA： TestClass；beginAAA := TestClass.Create;TryAAA.Add;finallyAAA.Free;end；AAA := TestClass.Create; 改为 AAA := TestClass.Create(true);或者在最后...

一个主要的区别立即浮出水面 - 在后一种情况下,Create构造函数必须是虚拟的,以便可以基于TMyObject构建支持Clone的类层次结构. 假设这不是问题 - TMyObject和基于它的所有内容完全在我的控制之下.在Delphi中进行复制构造函数的首选方法是什么?您觉得哪个版本更具可读性?你什么时候使用前者或后者?讨论.:) ...
You can also take look at the implementation of _ClassCreate in System.pas if you really don’t believe that Delphi behaves in this way. ugasoft 2008-07-26 at 2:47 am Does the Berived object never exist? (probably it doesn’t) ...

I am new to C++ and I think I may have thrown myself in a bit too deep!! I have programmed before in Delphi and Java so I think this may be more of a syntaxical problem. I am trying to create a class and, on calling the constructor, pass a filename to the constructor. As it...
