Swing-JTree.rar_jtree_jtree Demo_swing 树

首先来看一下展示界面，JTree 的特点有：节点可拖拽，根据输入生成目录，右键有菜单，点击触发事件等

JTable 的特点有：含有隐藏列，可以进行翻页，列中含有下载按钮等

在来看一下代码吧，基本代码由 Eclipse 上的 WindowBuilder 进行拖拽式产生的，所以看起来有点乱，不过没事

在使用 WindowBuilder 的时候要画 JTree 和 JTable 时要注意，这两个有几个共同点，必须放到 JScrollPanel 中，因为这两个控件的内容长度会发生突然变化，

所以要使用 JScrollPanel。

BTW：如果要使用 WindowBuidler，除了在 Eclipse 上安装插件，最方便的方法是直接下载含有该插件的 Eclipse 版本：
