質問

I tried to do this with this piece of code:

JFileChooser chooser = new JFileChooser();
int retval = JFileChooser.CANCEL_OPTION;
chooser.setFileSelectionMode( JFileChooser.DIRECTORIES_ONLY);
retval = chooser.showDialog(null, "Select");    

But it didn't work. Console just waited for input...

役に立ちましたか?
