说明：  很明显，在设计“图形用户界面程序”时离不开组件和组件的布局。但很奇怪，在我们的教材中没有对组件及组件的布局进行讲解，也没有这方面的具体例子。所以仅通过本教材的学习，是不可能设计出“更多更好的图形界面程序”的。为了弥补教材中的不足，撰写此文，供希望了解“图形界面程序”设计老师和同学参考。
(Clearly, in the design of " graphical user interface procedure" can not be separated when the layout of components and components. But it is strange that in our textbooks is not right components and components to explain the layout, and no concrete examples in this regard. Therefore, only through the study of this material is impossible to design a " more and better graphical interface procedure" . To compensate for the lack of textbooks, writing this article, for want to know, " Graphical Interface Program" design teachers and students for reference.)
