很多初学者在用Java布局器自动布局画界面时，经常遇见不知道如何定义区域大小或按钮之间的距离等问题。我写过一篇《实现JAVA手动布局中各个组件能随窗口变化的方法》的文章，有读者反映算坐标不好算，问能不能用布局器实现文章中的界面。其实自动布局也可以解决定义区域大小或按钮之间的距离等问题，只是没有手动布局那么灵活。下面我就举一个例子。 -many beginners in using Java for automatic layout interface layout painting, met often do not know how to define the size of the region or the distance between button issues. I wrote a "JAVA manual configuration of the various components will change with the window," the article, the reader reflect not count count coordinates, can ask the layout used for the realization of the article interface. In fact, automatic layout can be resolved definition of the size of the region or the distance between button issues such as manual layout is not so flexible. Now I would like to give an example.
