为什么工具栏的菜单没有图标，就只有那么一小丁点！？找不出问题啊
----------------解决方案--------------------------------------------------------
再说明一点，我在当前文件夹里有个Images文件夹，里面有比如New.gif、Open.gif等等的工具栏图片。

你的代码又长又没注释
我也盲目了
----------------解决方案--------------------------------------------------------
水平有限，没注释的代码看得眼睛都花了！
----------------解决方案--------------------------------------------------------
呵呵，不好意思，我看代码很少看注释，所以自己也很少写注释！
不过我问题解决了，还是麻烦你们了！
