问题描述

有人可以清楚地解释这句话吗?我想知道为什么对于应用程序程序员来说，使用Focus并不更好.谢谢.
焦点是主要用于自定义控件作者的低级方法.相反，应用程序程序员应该对子控件使用Select方法或ActiveControl属性，对窗体使用Activate方法."

Could someone explain this sentence clearly? I want to know why for application programmers, use Focus is not better. Thanks.

推荐答案

在这两种情况下，您都在告诉父表单将重点放在子表单上告诉孩子专注. b/c这可能是更好的选择，它更有可能在父级上引发正确的事件，或者类似的事情.我希望.

In both cases, you''re telling the parent form to focus on the child, instead of telling the child it is focused. This is probably better b/c it''s more likely to raise the right events on the Parent, or something like that, I expect.
