JFileChooser in mode FILES_ONLY

Hi,
I've a little problem with the JFileChooser.
I open a JFileChooser in FILES_ONLY mode with a default filename.
The default filename is displayed fine but when I click on a directory name my filename is overwritten by the selected directory name.
Because I can only select files (Files_Only) this is not normal and not consistant with other Windows applications.
I work with SDK 1.3.1 on a windows machine.
Below you can find my code.
Is there a workaround for this ?
Rgds,
Piet
      String originalFileName = "MyFile.doc";
      JFileChooser fc = new JFileChooser();
       fc.setFileSelectionMode(JFileChooser.FILES_ONLY);
       fc.setSelectedFile(new java.io.File(originalFileName));
       int returnVal = fc.showOpenDialog(this);

I am running java 1.4.2 and the code that you have posted worked exactly like you wanted. I copy & pasted in to my ide, replaced fc.showOpenDialog(this) with fc.showOpenDialog(new JFrame()) and ran it. The displayed file "MyFile.doc" did not change when I browsed to different directories.
I tried both the Metal and Windows plaf's, both worked.
This probably doesn't help you on 1.3.1, but at least you know it was fixed at some point.

JFileChooser, how can you allow the user to select MORE than 1 file?

Hello everyone.
I want to allow the user to select multiple files from a directory, not just 1, but not just the whole directory.
Currently I see these 2 options from looking at the sun's JFileChooser demo:
//Create a file chooser
        fc = new JFileChooser();
        //Uncomment one of the following lines to try a different
        //file selection mode. The first allows just directories
        //to be selected (and, at least in the Java look and feel,
        //shown). The second allows both files and directories
        //to be selected. If you leave these lines commented out,
        //then the default mode (FILES_ONLY) will be used.
        //fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
        fc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);but both don't allow the selection of more than 1 file.
When I say, select more than 1 file I mean the user can hold in SHIFT or CTRL and select files.
Any ideas how to do this?
Thanks!

Combining File Chooser and this MP3 class

Hello all,
I was curious if anyone could help me figure out how to get a file to actually load once it is used with this code.
I'm unfamiliar with how it works and I was hoping for an explanation on it.
I wasn't sure if I had to have the program recgonize that I would like to load a mp3 or if it just would load it automatically...
Essentially, I want to be able to load a mp3 if I use the file chooser.
I can try to clarify my question more if anyone should need it.
Thank you

Thanks for the link
I've been looking over the sections and still confused with the code.
It's obvious that I have to do something with this portion of the code:
public void actionPerformed(ActionEvent e) {
    //Handle open button action.
    if (e.getSource() == openButton) {
        int returnVal = fc.showOpenDialog(FileChooserDemo.this);
        if (returnVal == JFileChooser.APPROVE_OPTION) {
            File file = fc.getSelectedFile();
            //This is where a real application would open the file.
            log.append("Opening: " + file.getName() + "." + newline);
        } else {
            log.append("Open command cancelled by user." + newline);
}I'm just not sure what.

Why does is not show the radio buttons

I want to display the buttons in a row then radio button in a row under the button and then log scroll pane under the radio buttons. This is my code:
        //Add the buttons and the log to this panel.
        add(buttonPanel, BorderLayout.PAGE_START);
        add(radioPanel, BorderLayout.CENTER);
        add(logScrollPane, BorderLayout.CENTER);When i run it it display the buttons and the logsrollpane. Why does it not display the radio buttons?

Thanks guys.
This is my problem. We have a big system that produce lots of log files and the software testers have to manually have to go through the logs file and look for a certain XML tags in the log file.
What I want to do is help the software testers my developing a small tool that will allow them to open a log file and then click on a radio button corresponding to a xml tags that they are looking for and automatically highlight the tags in the file in yellow color .
I am not sure how feasible this is and I am stuck.
This is what I have done so far.
Can you please guys help me go forward.

JFileChooser DIRECTORIES ONLY mode

When I use a JFileChooser with the mode as directories only, I want to show the full path of the directory selected by the user in the text box next to the File Name: label. However all that is being displayed is the name of the directory itself and not it's full directory path?
JFileChooser jfc = new JFileChooser();
jfc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
String strDirSel = jfc.getSelectedFile().getPath();
jfc.setSelectedFile(new File(strDirSel));
Any suggestions of how to manage this, would be appreciated?

I thought the AWT one is a FILES_ONLY type of browser as well.
I just figured a kludge that I'm willing to live with. I added a PropertyChangedListener to tell when a file was selected. This has the effect of drilling down on single-click. I first tried the code that is commented out. Although my debugging comments show up on the console, the directory was not changed for DIRECTORY_CHANGED_PROPERTY. Oh well.
jFileChooser.addPropertyChangeListener(new PropertyChangeListener()
public void propertyChange(PropertyChangeEvent evt)
if (evt.getPropertyName().equals(JFileChooser.SELECTED_FILE_CHANGED_PROPERTY))
System.out.println("sfcp");
File file = (File) evt.getNewValue();
if (isShowing())
if ( file.isDirectory())
jFileChooser.setCurrentDirectory(file);
if (evt.getPropertyName().equals(JFileChooser.DIRECTORY_CHANGED_PROPERTY))
System.out.println("DC");
File file = (File) evt.getNewValue();
if (isShowing())
System.out.println("is showing");
if (file.isDirectory())
System.out.println("is directory");
jFileChooser.setCurrentDirectory(file);

Is it possible to use fullscreen and exclusive mode with a jfilechooser?

is there a way to use them together? while in fullscreen exclusive mode the jfilechooser doesn't attach to fullscreen window and it halts the program.. I've tried setting the parent frame as the fullscreen frame but it's all glitched.. am I missing something?
thank you,
best regards,
Jacopo

Default JFileChooser to details mode

Hi all,
In JFileChooser there are 2 JToggleButtons : "details" and "List.".
each one switch the file chooser to corresponding view.the default is List view mode.
I want my filechooser to always default to details view mode . is there a clean and easy way to achieve this ?
thanks.

In future Swing related question should be posted into the Swing forum.
I am pretty sure (99%) the answer to your question is no.

How to set the the file selection mode of JFileChooser

hi,
i want to set the file selection mode to directories only for JFileChooser class but when i run the code it does not select the folder adn opens the folder instead. i want the user to select a folder from the file system . any ideas?

Sorry, I misunderstood you question. I thought that you already set it to choose Directories and wondered when you can't select them when you double-click.
use JFileChooser.setFileSelectionMode(int). This should solve your problem.
Here is an example:
        JFileChooser jf = new JFileChooser();
        jf.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
        jf.showDialog(this, "Select");
        System.out.println(jf.getSelectedFile());
unformatted
JFileChooser jf = new JFileChooser();
jf.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
jf.showDialog(this, "Select");
System.out.println(jf.getSelectedFile());

Quick question: JFileChooser mode

Hello All,
I have a bit of a problem regarding JFileChooser. My application has 1 main window, and subwindows which are created when certain actions are performed on the main window. I want to create a file chooser when I perform certain actions on one of the subwindows, and make that chooser modal with respect to the subwindow only. I want to be able to perform other operations on the main window, even if the file chooser is shown. Is this possible?
Currently, I have a JFileChooser sublclass, and I tried to override the createDialog() method so that I can manipulate the shown dialog's modal property. So far this approach of changing the modal property does not get me close to the behavior I want. [ The dialog does not block when modal is set to false, and setting it to true makes the other windows inoperable. ]
Does anyone have any idea regarding this problem? Please let me know.
Thanks.
Regards,
Cocoh

I am pretty sure that the modality (is that a word?) of a Dialog is by definition application wide. To do what you want you will probably have to manually enforce the single window modality. You could probably do this by adding a WindowFocusListener to your disabled window that will force focus to your quasi-modal window.
Hope this helps,

JFileChooser : Exception occurred during event dispatching

Hi,
I'm having problems with sorting in 'Details' view of JFileChooser. I'm getting the following NullPointerException when I try to sort by clicking on the header of the JTable which I get in 'Details' view of a JFileChooser.
Exception occurred during event dispatching:
java.lang.NullPointerException

Any operation performed in the JFileChooser after this exception will generate the same exception & no action is performed. I'm using Java 1.6.0_24. Strangely, this is happening only in client-server mode. Staand-alone is working fine.
Please provide some urgent inputs to this problem
Thanks
Dilip

Thanks 4 d reply mKorbel, I'm not creating a TableModel. I'm just creating a JFileChooser as shown below.
JFileChooser fileChooser = new JFileChooser(location);
fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
fileChooser.setMultiSelectionEnabled(false);
fileChooser.setDialogTitle("Choose File");
if (fileChooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
Now, the scenario is to bringup the FileChooser, go to Details view, apply sort on any column. This action creates the mentioned NullPointerException.

JFileChooser and FilePermission write

Hi,
I use a JFileChooser in a swing application like this :
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
if (fileChooser.showOpenDialog(MainJWS.this)== JFileChooser.APPROVE_OPTION) {
dir2Name = fileChooser.getSelectedFile().getPath();
I want the application to only get rights on FilePermission to read. So I change my policy file like this :
grant {
permission java.io.FilePermission "<<ALL FILES>>", "read";
So when the appli runs, there is a PermissionException on write right. Is there any way to use the JFileChooser only on a read mode ?
thanks.

Thanks, I saw it.
Maybe there 's another way, with FileDialog ? Or with JFileChooser and FileSystemView ?
any idea ?

JFileChooser's approve button text changes when file

I have a JFileChooser used for loading some XML file(s). We want the approve button's text to be "Load". When I bring up the dialog, the button text initially reads "Load", when I select a directory, it reads "Open", if I select a file again, it goes back to "Load". So far, so good.
The problem comes when using it in a non-English language. When I bring up the dialog, the button text initially reads the appropriately translated "Load". However, when I select a directory, it changes to the English "Open". I do not see a method to use to adjust this text. Am I missing something, or is this a bug?
Any help is greatly appreciated.

Here's some code I'll put into the public domain:
package com.graphbuilder.desktop;

import java.awt.event.*;
import javax.swing.*;
import java.util.Stack;
import java.util.Vector;
import java.util.StringTokenizer;
import java.io.File;
<p>Attempt to improve the behaviour of the JFileChooser. Anyone who has used the
the JFileChooser will probably remember that it lacks several useful features.
The following features have been added:
<ul>
<li>Double click to choose a file</li>
<li>Enter key to choose a file after typing the filename</li>
<li>Enter key to change to a different directory after typing the filename</li>
<li>Automatic rescanning of directories</li>
<li>A getSelectedFiles method that returns the correct selected files</li>
<li>Escape key cancels the dialog</li>
<li>Access to common GUI components, such as the OK and Cancel buttons</li>
<li>Removal of the useless Update and Help buttons in Motif L&F</li>
</ul>
<p>There are a lot more features that could be added to make the JFileChooser more
user friendly. For example, a drop-down combo-box as the user is typing the name of
the file, a list of currently visited directories, user specified file filtering, etc.
<p>The look and feels supported are Metal, Window and Motif. Each look and feel
puts the OK and Cancel buttons in different locations and unfortunately the JFileChooser
doesn't provide direct access to them. Thus, for each look-and-feel the buttons must
be found.
<p>The following are known issues: Rescanning doesn't work when in Motif L&F. Some
L&Fs have components that don't become available until the user clicks a button. For
example, the Metal L&F has a JTable but only when viewing in details mode. The double
click to choose a file does not work in details mode. There are probably more unknown
issues, but the changes made so far should make the JFileChooser easier to use.

JFileChooser - show files and directories only select directory

I need a JFileChooser that will display directories and zip files but only allow a directory to be selected.
basically i need to be able to select a certain directory that contains a certain zip file, so to make it easier to find i want the zip files to show up so i can find the correct directory...
I tried...
        JFileChooser jfc = new JFileChooser();
        jfc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
        jfc.setFileFilter(new FileFilter() {
            public boolean accept(File f) {
                if (f.isDirectory()) {
                    return true;
                else if (f.getName().endsWith(".zip")) {
                    return true;
                return false;
            public String getDescription() {
                return "testing";
        });but that only displays directories in the GUI.
The javadoc for the setFileSelectionMode() says, "Sets the JFileChooser to allow the user to just select files, just select directories, or select both files and directories. The default is JFilesChooser.FILES_ONLY. " ....which makes you think that setting the file selection mode only alters what can be SELECTED...however it alters what is displayed as well.
...any ideas?
thanks

This should display the files of interest provided the filter is tuned to do so, and allow you to select either the file of interest or the folder... If you select the file, then folder it is contained is returned.
JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory(new java.io.File("."));
MyFileFilter filter = new MyFileFilter();
chooser.setFileFilter(filter);
chooser.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
int returnVal = chooser.showOpenDialog(this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
System.out.println(chooser.getCurrentDirectory());
}

JFileChooser view are listed as details

How can I change the way files are shown in my JFileChooser?
I want to show them like Windows XP shows the details mode.
Besides, I still want to order them in Descending names order.
So far I have this:
The viewer:
class PreviewPanel extends JPanel {
        public PreviewPanel() {
            JLabel label = new JLabel("EDI Viewer", SwingConstants.CENTER);
            setPreferredSize(new Dimension(350,0));
            setBorder(BorderFactory.createEtchedBorder());
            setLayout(new BorderLayout());
            label.setBorder(BorderFactory.createEtchedBorder());
            add(label, BorderLayout.NORTH);
            add(previewer, BorderLayout.CENTER);
    }The JFileChooser Box:
private PreviewPanel previewPanel = new PreviewPanel();
chooser = new JFileChooser(new File(entryDir));
        chooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
        chooser.setAccessory(previewPanel);
        chooser.addPropertyChangeListener(new PropertyChangeListener() {
            public void propertyChange(PropertyChangeEvent e) {
                if(e.getPropertyName().equals(JFileChooser.SELECTED_FILE_CHANGED_PROPERTY)) {
                    previewer.configure((File)e.getNewValue());
        });Anyone's got something to say about this?
Thanks

I have chaged something but still not working, now I am using FileSystemView:
    class EDIFileSystemView extends FileSystemView {
        public File[] getFiles(File dir, boolean useFileHiding) {
            File newDir = new File(entryDir);
            File[] files = newDir.listFiles();
            Comparator nameComparator = new Comparator(){
                public int compare(Object o1, Object o2){
                    String name1=((File)o1).getName();
                    String name2=((File)o2).getName();
                    return name2.compareTo(name1);
            Arrays.sort(files, nameComparator);
           // Here the files are shown in the correct order
           for(int i=0; i<files.length; i++){
                System.out.println("File: "+files);
return files;
public File createNewFolder(File containingDir) throws IOException {
return containingDir;
Calling JFileChooser (here the files DOES NOT appear in the correct order):
chooser = new JFileChooser(new EDIFileSystemView());
        chooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
        chooser.setAccessory(previewPanel);
        chooser.addPropertyChangeListener(new PropertyChangeListener() {
            public void propertyChange(PropertyChangeEvent e) {
                if(e.getPropertyName().equals(JFileChooser.SELECTED_FILE_CHANGED_PROPERTY)) {
                    previewer.configure((File)e.getNewValue());
Why is this happening?
