试图模仿 Jbuilder拖拽生成代码功能

说实话，写的挺烂的，本来想做好点，半途而废了，懒，

里面最复杂的功能是菜单栏目，点击menu标签，在点 menu更改, 弹出一个框，如图：

里面输入这种格式。

文件(新建,另存&)
编辑
查看

懂了吧，另存& 表示这个子item被默认添加了click监听器,

好了，自己试试吧。

运行，只要在mian中 new GUIBuilder();  只有一个类，无需部署.
就ok 了。

点击左边的按钮，变成红色后，点右边的画布 ，就放上去了。
所有组建，右下角可以拖拽大小。。。

生成的代码， 类叫MyFrame，只要建立一个MYFrame.java,代码放进去，
直接在mian 中new MyFrame(); 运行生成的代码。

这玩意儿怎么用的话，运行了，乱点一气，就知道了。。
