filechoose高级问题，请教高手~

Question

windows 可以按大图标,小图标,详细资料等模式查看,而filechooser中没有相应的方法设置,只能在它出来后,用鼠标来选择,有没有办法在代码里解决?高手们有办法吗?

为了回答这个问题，也算是费劲了心机。首先查看了源代码，没有发现任何可以的方法，甚至连什么时候点击了该按钮都无法得知。无奈使用了DEBUG大法，仔细观察JFileChooser的控件结构，终于给出如下答案：    /**
     *  测试filechooser，控制对话框中控件。

        f.show();
        
        final JFileChooser fc = new JFileChooser();
        
        /*fc.addPropertyChangeListener(
                new PropertyChangeListener (){
