看了下网上的gui教程都没有什么比较好的，不管是java、安卓还是ios，设计UI都应该先从布局上来考虑，而不是看一点写一点。如果你一来就想着用绝对布局，我只能说这种思想很危险，砖慢慢搬吧。

这个是中期考试的时候边学边做的一个东西，做一个eclipse的搜索gui，类似下图，其实也就是个苦力活。

原图：

我的代码跑出来的图：

先说布局，我直接给张图：

设计到的控件(从上到下、从左到右的顺序)：

North区：

JLabel、JComboBox

JRadioButton

JCheckBox

South区：

JButton

值得一提的是panel的titleBorder，就是这个玩意儿：

这是我花时间最长的地方，因为我一直以为那是个控件，其实是panel的Border，像这样设置一下panel的Border属性就可以了：

JPanel panelDirector = new JPanel();
panelDirector .setBorder(BorderFactory.createTitledBorder("Director"));

其他都没什么问题了，我直接贴代码了：
