Delphi:Delphi得到输入框焦点时背景变色，得到组件焦点并设置其属性，其实不只是Delphi程序应该这么做，其它的一些编程语言写出来的软件了应该这样啊，为了有一个好的操作体验，让软件更人性化这是我们的目标，虽然这是一个不能再小的功能，但却让用软件的用户觉得好用，不是很值得吗？

-Delphi: Delphi get the focus when the input box background color, get the focus component and set its properties, in fact, not just Delphi program should do some other programming language to write software that should be so, ah, in order to have a good operating experience, let the software more user-friendly and this is our goal, although this is no longer a small feature, but it allows users to use the software, feel good, is not it worth it?
