How can i deduct the change of Filetype in the Filechooser Combobox ,since
i am entering some filename in the textfield of FC , if i change the File type the text inside the textfield is deleted .. i dont want to delete the text if i choose "all files " ..Can anyone suggest me how to do..?
2.If i do some file/dir search for some letter ,the Scrolbar in List is not moving ,
but the character is selected ..

You can add a PropertyChangeListener to JFileChooser and listen for JFileChooser.FILE_FILTER_CHANGED_PROPERTY events. The problem you describe is covered by the following bug report:

That's not an error from Java, as far as I know. Something else is producing it. Look over these search results for a case that matches what you see:

JFileChooser problem - it will not display

I have read the tutorial on JFileChoosers and understand the basics, however, my application will simply not display a File Chooser. I select the menu option "open file" and the command prompt window just spews out dozens of garbage. The code is below if there are any FileChooser "Pros" out there. The FileChooser is selected for loading in the actioPerformed method. Thanks for any assistance.

Jfilechooser - problem with windows mapped dirs

My Documents, Desktop and other windows mapped directories
or network drives cause performance problems for the java file
chooser class.
I think because the file chooser has to resolve
ambiguous paths for each file.
i.e.
1. Desktop\My Documents\myfile.doc
2. c:\documents and settings\me\My Documents\myfile.doc
3. Desktop\My Computer\c:\documents and settings\me\desktop
4. Desktop\My Computer\c:\documents and settings\me\my
documents\myfile.doc
Most of our users are using xp and save most of their
files to the My Documents directory.
I need to find some work around. If this is not possible
I could do with some tips on writing a directory service
that will perform better on windows architecture.
regards,
Paul Cunningham

It's still a serious problem. I am using WinXP with java 1.4.1_01. A folder on a mapped network drive with about 450 files in it takes an enormous amount of time to open & display. Once the file icons appear in the JFileChooser, scrolling and selecting in the JFileChooser is horrendously unresponsive.
This problem (or related ones) seems to have been around for a long time. I wonder why it doesn't get fixed?

JFileChooser problem under Linux

I am using a JFileChooser component to allow a user to select files for which status information is displayed in my gui.
I am using a native method to get permissions etc on the choosen file and everything works well. If the user chooses a file which is actually a link or a fifo or a device node or a regular file, everthing works fine - the JFileChooser returns the File selected. I use the File.getPath() function and my native method gives me back permission information for display.
My problem is when I enable multiple selections in the JFileChooser. For regular files, links, directories it works fine. But if the user try's to select a file which is actually a device node then the JFileChooser won't allow the user to select one.
Is there any way I can overcome this problem?
TIA
Paul

Hi,
Windows is completely open and permissible regarding to user permissions. Linux is not. Check if the user you are trying to execute this java file has the permission to open a socket, for example. If he doesn't have it, then an exception would occur.

Resizng JFileChooser problem!!

Hi,
i have really wierd problem with JFileChooser.FileChooser is displayed very wide.It fills my screen.I use j2sdk1.4 and Windows XP.I used
fileChooser.setPreferredSize(new Dimension(450,280));
it is resized.But now ComboBox that allows me to choose where to save file is shown too long.Also buttons for "up one level","list","details" are not displayed.Please help me.
greetings

This is because there is a long string in the drop-down list at the top (possibly you have a meapped drive with a long path). For some reason (a bug?) JFileChooser seems to resize the dor-down list (and hence itself) to fit the longest path - at least on XP

JFileChooser problem opening just java files

Hi everyone, trying to write simple text ed. that will only open java files (part of JFileChooser). Yes have looked at API but so stupid that i couldnt get it to work can anyone help?
public void openFile() {
          BufferedReader in = null;
          try {
               JFileChooser chooser = new JFileChooser();
               //---Open Java Files only---
               if (chooser.showOpenDialog(null)
               == JFileChooser.APPROVE_OPTION) {
               File selectedFile = chooser.getSelectedFile();
               in = new BufferedReader
                         (new FileReader(selectedFile));
     catch(FileNotFoundException e) {
          JOptionPane.showMessageDialog
               (null, "Bad Filename. Try Again");
     catch(IOException e) {
          JOptionPane.showMessageDialog
               (null, "Corrupted File. Try Again");
     finally {
          if (in != null)
               try {
                    StringBuffer buffer = new StringBuffer();
                    String text = new String();
                    text_chat.setText(text + "\n\n");
                    while((text=in.readLine())!=null)
                         buffer.append(text+ "\n");
                    text_chat.setText(buffer.toString());
               catch(IOException e) {
                    JOptionPane.showMessageDialog
                         (null, "Error closing File.");
}

Can you tell me how did you solve the problem? Right now I am encounter ing the same problem. The java files on JFileChooser did not show up!

JFileChooser Problem (Extra Window)

Hi, when i run my code i curently am getting an extra window when i press open or cancel in my GUI for my JFileChooser. below is an example of what im initializing.
    private void jbInit() throws Exception
    contentPane = (JPanel) getContentPane();
    contentPane.setLayout(xYLayout1);
    setSize(new Dimension(570, 307));
    setTitle("Open File");
    jFileChooser1.setMaximumSize(new Dimension(570, 307));
    jFileChooser1.setMinimumSize(new Dimension(570, 307));
    jFileChooser1.setPreferredSize(new Dimension(570, 307));
    contentPane.add(jFileChooser1, new XYConstraints(4, 0, -1, -1));
    jFileChooser1.addChoosableFileFilter(objectFilter);
    jFileChooser1.addChoosableFileFilter(textFilter);
    jFileChooser1.setMultiSelectionEnabled(false);
    jFileChooser1.setAcceptAllFileFilterUsed(false);
    int returnVal = jFileChooser1.showOpenDialog(this);
    //Figure out how to destroy the extra thing from below statement.
    if (returnVal == jFileChooser1.APPROVE_OPTION)
      selectedFile = jFileChooser1.getSelectedFile().getName();
      selectedDirectory = jFileChooser1.getCurrentDirectory().toString();
      if (true == textFilter.getSelected())
          setExtension("txt");
      if (true == objectFilter.getSelected())
          setExtension("obj");
    if (returnVal == jFileChooser1.CANCEL_OPTION)
      setExtension("Cancel");
    }If any more code is needed ask away.
i really have no clue why the extra window is there i have tried this.dispose() and other things to try and get rid of it but nothing seems to work.
Any help is greatly appreciated.

JFileChooser problem - A bug ???

Hi all,
i am facing a unique problem with the JFileChooser. when i go to the "Look in" drop down list and select "Network Neighborhood", what i expect is to get a list of all computers on my LAN. i do get it, but the filechooser does seem to recognise the system names. the names that r displayed seem to be kind of substrings of "Network".
E.g: etwork, ft Network, soft Network etc..., instead of proper system names.
but when i double click on a folder, then it displays the shared folder names correctly, and also identifies the system name. it says something like:
"folderName" on "systemName"
if the filechooser is able to recognise the system name here, then why does it not display the system names properly in the aforesaid place (ie, when i select Network Neighborhood) initially.
am running jdk ver 1.4, on a windows 98 system. is it somekind of a bug or am i missing something that i need to do ? could not find any help from the API.
any idea anyone ???
thanks

1.4.2 has a fix for JFileChooser, although I am not
sure its this problem, or hopefully the one I see
often, when I click the drop down box to navigate to a
network drive, it sometimes takes a VERY long time, on
the order of hours, for the drop down to show up. On
of our clients is seeing this now, so I am not sure
why this is.The problem here is that Windows98 Network communication is appalling slow a lot of the time and some bits of it is broken.
Getting the members list from a network can take an age simply because you sometimes have to broadcast a query on that network to find all the machines on it. This is not a Java related problem (although I suspect that VM support for Windows98 has slipped in priority ).

JFileChooser problems

Hi
I've written a small GUI for a college project. I have 2 JFileChoosers one which gets a single file(this works fine), the second I have set to directories only and I want to retrieve a File []. This doesn't seem to work it just returns an empty File []. I've tried using the myJFileChooser.getSelectedFiles method and
File a = JFileChooser.getSelectedFile();
File [] b = a.listFiles();
but neither have worked. Here's my code bellow. Thanks in advance for the help

This works fine for me, and print the selected directories.

JProgressBar & JFileChooser Problem!

Hi! I'm writing an application for reading the names of all files in one CD/DVD and I runned into an error. The CD/DVD Drive is choosen with JFile Chooser.
This is the code:
                dia = new JFileChooser();
          dia.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
          int option = dia.showOpenDialog(this);
               if(option==JFileChooser.APPROVE_OPTION)
                    zacuvajPodatoci(dia.getSelectedFile().toString());
public void zacuvajPodatoci(final String path)
          citajB.setEnabled(false);
          cdTitle.setEnabled(false);
          canticeBr.setEnabled(false);
          redBr.setEnabled(false);
          File file = new File(path);
          File files[] = file.listFiles();
          Vector dirs = new Vector();
          pbar.setMaximum(files.length);
          for(int i=0; i<files.length; i++)
               if(files.isDirectory())
                    v++;
                    dirs.add(files[i].toString());
                    updateProgressBar();
               System.out.println(files[i].toString());
private void updateProgressBar() {
                    pbar.setValue(v);
Now when OK is clicked the app blocks, the file chooser doesn't dissapeare, and when the method is over, then the GUI is upadated and then I see the progress bar at 100%. What sould I do? I must see the progress bar while the method is running. Please help!

JFileChooser problems in GTK look&feel

Hi,
the JFileChooser dialog is just ugly and not acceptable when using the GTK look&feel, there are so many layout problems and display errors. It also does not look like the native dialog. I'm using Ubuntu Linux 7.10 and Gnome 2.20.
My application uses the GTK look&feel, because most of the normal widgets look nice. Is there a way to use the same JFileChooser dialog layout as it is in the Metal look&feel when using the GTK look&feel? This would be an acceptable workaround...
Thanks,
Stefan

I don't believe it will be supported under any platform but *nix platforms. The GTKLookAndFeel currently requires native theme information which is not available on the Windows platform.

Help with "simple" JFileChooser problem...

Hi all,
how do I set the font in a JFileChooser???
I have tried everything, but it always uses the Look & Feels default font setting. Can I change the default Look&Feels font setting?
Greatfully for any suggestions!
Cheers
Anders ;-D

Hello!
You can use the UIManager, e.g. UIManager.put("FileChooser.font", new Font("Arial",
Font.BOLD, 14);
Well, that didn't seem to help with my case either. So I tried something else: I overrided all of the defaults by using UIManager.put(key, value) this way I got all of the Fonts in the JFileChooser to change.
Correct me if I'm wrong... ;)
- Cathra -
Sample Code that performs the requested:
// Prepare the resources
FontUIResource font12Arial = new FontUIResource( "Arial", Font.PLAIN, 12 );
// Put values into UIDefaults (before initializing the JFileChooser)
UIManager.put( "ToolTip.font", font12Arial );
UIManager.put( "OptionPane.messageFont", font12Arial );
// shown for example
UIManager.put("FileChooser.openButtonText", "OpenUp");
UIManager.put("Button.font", font12Arial);
UIManager.put("Label.font", font12Arial);
UIManager.put("Table.font", font12Arial);
UIManager.put("TextField.font", font12Arial);
UIManager.put("ScrollPane.font", font12Arial);
UIManager.put("ComboBox.font", font12Arial);
UIManager.put("CheckBox.font", font12Arial);

Jfilechooser problem with getFile()

hi all
i have my application that, when a button is pressed, instantiates a fileChooser:
private void b_scegliActionPerformed(java.awt.event.ActionEvent evt)
        f_choos f=new f_choos();
        File fil=f.getFile();
        System.out.println("selected "+fil.getName());
}and my f_choos class with this methods;
public f_choos()
        initComponents();
        chooser.addChoosableFileFilter(new ImageFilter());
        chooser.setFileView(new ImageFileView());
        chooser.setAccessory(new ImagePreview(chooser));
        int result = chooser.showOpenDialog(null);
        if(result == chooser.APPROVE_OPTION)
            if(chooser.getSelectedFile()!=null)
                String name= chooser.getSelectedFile().getPath();
                getFile();
    public File getFile()
        return chooser.getSelectedFile();
    }my problem is that, also when i press the "cancel " button, the file pointed by my fChooser is selected, but i want to be returned null
anyone could help me?
thanx in advance

Perhaps you could do something like this
public class f_choos {
    private File file;
    public f_choos() {
        initComponents();
        chooser.addChoosableFileFilter(new ImageFilter());
        chooser.setFileView(new ImageFileView());
        chooser.setAccessory(new ImagePreview(chooser));
        if(chooser.showOpenDialog(null) == chooser.APPROVE_OPTION) {
                file = chooser.getSelectedFile();
    public File getFile()    {
        return file;
}
