【开贴感谢】－－李晔兄和Linyv(vv)兄请进

[KomaX]

非常感谢李晔兄和Linyv(vv)兄在百忙之中抽出时间来回答我一个菜鸟的问题，
特别是李兄之诲人不倦态度令我感到CSDN的温暖。

虽然自己分不多，但是分数除了拿来散，更是应该给像李兄和Linyv(vv)兄这样热心帮助别人的Goodman。

再次感谢 :)

我把李兄的程序最后改为：
if(sf.isDirectory()){
model.addRow(new Object[]{sf.getName(),sf.getPath()});
}

这样就可以显示目录名和目录路径地址（我事先已经加了一列了）

但是有个问题，李兄的每次Open都会在上一次打开的情况下继续往Table下面添加。
要是每次调用open按钮都可以刷新table，应该怎么该呢？或者加一个按钮？

李晔兄和Linyv(vv)兄呢？:)

估计又在热心帮助人了 :)

UP 让他们看到

只要在processDoubleClicked()部分加上自己的代码就可以了。

一點改進,建議你仔細看一下javadoc
