新闻播报最新/优化设计答案五年级上册
最近在看“企业快信”的源代码，这个项目的好友列表是用JTree实现的。
在理解了它的写法之后，就想把JTree控件的使用熟悉一下。于是自己写了个小练习，就是显示数据库中的用户名和图片路径在JTree中，并且还可以添加用户，同时在JTree中显示。
JTree中，有TreeCellRenderer接口，可以用类来实现这个接口。在这个接口相应的方法中，可以对树中的节点进行设置。如我就是在这个方法中设置节点的大小，以及判断节点，然后将节点用一定的样式显示。
然后，再可以写一个类，继承至JTree,为它设置根节点DefaultMutableTreeNode root和DefaultTreeModel treeModel。然后设置它的setCellRenderer为刚才写的继承TreeCellRenderer的类。那么就可以添加节点，用root.add(new DefaultMutableTreeNode(**))方法，和root.remove()方法来移除节点。值得注意的是，setModel必需在setCellRenderer之后，而且，jpanel设为GridLayout(1,1)后再add JTree。
