说明：  Delphi窗口置顶实例、窗体透明，禁止使用最大化按钮和最小化按钮的编程实例，打开编译的程序后，你会发现程序的窗体是半透明状态，而且可以始终显示在最顶层，不会被遮挡，通过窗口中的几个控制按钮，还可以实现最小化最大化按钮失效、读取图标等功能，对新手来说，是比较实用的窗口编程例子。
(Delphi window top case, transparent window, the prohibition of the use of the maximize button and minimize button programming examples, open compiler program, you ll find out window procedure is transparent, and can always displayed at the top, will not be blocked, the control button through several window, also can realize the minimize button failure icon to read, and other functions, for beginners, is a more practical programming examples.)
