Create Directory Dialog box without specifying file name

Question

Hi all Programmers/Developers/JDC memebers
I would like to know in java is there any method or class which helps to give directory dialog box without specifying filename.
I mean to say if u have c,d,e drives and some directories under them
c:\dir1
c:\dir2
d:\dir1
d:\dir2
i want a dialog box,which dispalys all the directories of the selected drive and upon choosing/selecting that directory i should be able to get all the files under them.

Hi,
You can write a file filter for a JFileChooser, in the following way,
public class DirectoryFilter extends javax.swing.filechooser.FileFilter
public boolean accept(java.io.File file)
boolean filter = false;
if(file.isDirectory())
filter = true;
return filter;
public String getDescription()
return "Directories only";
//in your code
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileFilter(new DirectoryFilter());
fileChooser.showOpenDialog() etc. etc..
There's one small issue, by default JFileChooser has a filter called all files filter which you can select from the combo labled "files of type" . So, your file filter won't apply if this filter is chosen.
To disable the all files filter
use
fileChooser.setAcceptAllFileFilterUsed(false);
and only if you are on jdk1.3 or greater since this is a private method in the JFileChooser in 1.2.2 .
Hope this helps,
