Question To JFileChooser - OpenDialog

I use a JFileChooser to open a dialog for choosing a file:
JFileChooser fc = new JFileChooser();
int retVal = fc.showOpenDialog(m_main);
In these dialog is a button for creating a new folder. But the new folder is always named "New Folder" and I cannot rename it in this dialog. Can I set any property to the JFileChooser so that I can rename the new folder ? Or if this is not possible, can I set that the button for creating a new folder is not visible ?
Thanks for help, Nadine.

Hi.
The name "New Folder" is hardcoded in the FileSystemView, so theres no way to change it easily. Also no reference is saved for the new folder button in the ui.
You can write your own ui (you can copy most things, just don't add the create button) or you search through the components in the FileChooser until you find the right button and remove it...
Hope this helps

2 questions of JFileChooser,please !

Dear all,
I have have 2 questions about using JFileChooser:
1. How to disable " Create a new folder"?
2. How NOT to display the hidding files? It seems simply "chooser.setHiddingFilesEnabled(true)" dosn't take effect.
Thanks a lot.
Kevin

1. How to disable " Create a new folder"?This I don't know, but I know that in your filter, you can filter out directories as an option
2. How NOT to display the hidding files? It seems
simply "chooser.setHiddingFilesEnabled(true)" dosn't
take effect. what about chooser.setHidingFilesEnabled(false)?

Thanks a lot.

PS: Happy new Year !!!!

1.) JFileChooser: I have a JFrame with my JFileChooser

shows me just the ".txt" files ?Set a filefiler on your filechooser like this:
myJFileChooser.setFileFilter(new MyFileFilter() );
import java.io.File;

import javax.swing.filechooser.*;
public class MyFileFilter extends FileFilter {
    // Accept all directories and all txt files.

Newbie Question: Getting the file name from a JFileChooser

Hi,
I have a simple problem.
I'd like to get the filename that a user types into a JFileChooser Save dialog before they save a file.
How do I retrieve this name?
Cheers,
Chris Share

Hey it's ok, you're new. But one thing you've got to learn is to RTFM (Read the .... Manual). You'll answer own your questions much faster that way.
Take a look at the example at the top of:

JFileChooser and date format questions

I have a JFileChooser that currently works - I set the default directory and allow the user to select a file or enter a file name.
I have been asked to modify this to prepopulate the file name field on the JFileChooser.
How do I do that? It is not obvious which method to call to set the filename field.
Also, the file name needs to be a timestamp "*yyyyMMddHHmmss*.dat"
I tried creating the timestamp part with the following code, but it does not format as expected.
        String s = "";
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddddHHmmss");
        try
            java.util.Date now = new java.util.Date();
            java.util.Date dat = dateFormat.parse( now.toString() );
            s = dat.toString();
        }What is wrong with this?
Thanks.

I don't do Swing and this is also not the subforum for Swing questions. It has its own subforum.

JFileChooser question

Hey Guys,
My First post on the sun forums, so a big hello to you guys. I have a question in relation to best practice in querying something in one user interface, of another user interface. Suppose i have a class that consists on a TextField,JButton, and a JButton which opens a JFileChooser; i would like to return the value of the JTextField from the second GUI class to a calling gui class (gui1), once the OK button has been pressed. The second gui class consists of the following.
package UserInterface;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;

}and a call the class from a the first gui class as such
GUI 1
addImageItem.addActionListener(new ActionListener() {
             @Override
                  public void actionPerformed(ActionEvent arg0) {
                       imageChooser = new ImageChooser();
... remaining source of class remove as its not necessary to the questionhow can i query when the ok button has been pressed on the second gui class, so that the first gui knows when to take the value from the JTextField. Would i just put a method in the second gui which is a boolean that holds true or false whether its ok to take the value from the JTextField and query it like such...
//                       while(imageChooser.isStillOpen()) {
//                       }Hope that makes sense.

Thank you for your reply bharath.bravo, that has solved my question. Which i did as such, i provided a method in the second GUI class to enable me to add an ActionListener to the OK button. As such
      * this method allows other classes to add their action listeners to
      * the OK Button
      * @param e Action Listener from another class
     public void addActionToOKButton(ActionListener e) {
          okButton.addActionListener(e);
     }     I then added a accessor method, to get the value from the textfield; which i've implemented it as such:
imageChooser.addActionToOKButton(new ActionListener() {
                              @Override
                              public void actionPerformed(ActionEvent arg0) {
                                                                                                                //use imageChooser accessor method to get the value from the text field
                                   imageLocation = imageChooser.getLocationTextField();
                                                                                                                //DEBUG statement
                                   System.out.println("gui one recieved: " + imageLocation);
                                                                                                                //get rid of imageChooser window
                                   imageChooser.dispose();
                              }For the sake of clarity, in your first suggestion. You mentioned that i could implement the WindowListener Interface in the first gui, and add it as a Listener to the second gui. Would i do that like this, and what would be a prefferable way of doing this out of the two methods you suggested.
public class GUI extends JFrame implements WindowListener
     @Override
     public void windowClosed(WindowEvent arg0) {
          // TODO Auto-generated method stub
          //get value of jTextField using its public accessor method
add window listener to second gui, from the first GUI
imageChooser.addWindowListener(this);Regards,

JFileChooser Questions

Hi,
I have 2 questions concerning the use of JFileChooser:
1. When you use "Details" option to see the details of the files; the "Modified" column seems to show the time in "United States" format even if the local regional setting is something else. Is this the default behavior of the JFileChooser or is there something that I can do to change that?
2. It seems that you cannot just click on the column headers such as "Modified" to have the files sorted by that column like real Window's file chooser... Is that also the default behavior or is there something that I can do to change that?
Thanks....

JFileChooser Question .... wo hoo!

Hey there,
I have a question regarding the JFileChooser class. I have managed to instantiate a file chooser and specify that it display directories only, I have also worked out how to get information when the "Attach" button (my custom button) or the "cancel" button is pressed. When the "Attach" button is pressed I return a file object that selects the user selected directory. I then print the directory to the standard output. Unfortunately the entire selection is not being printed, only the top level directory relevant to the selection is being printed. If you are familiar with JFileChooser then you will probably know what it looks like when it is instantiated. To refresh a couple of areas of significance to my program are the "Look in:" section and the "File Name:" section.
I need my program to print the inforamtion in the "File Name:" section not the "Look in:" section as it is doing now. My code is as follows:
import java.awt.event.*;
import java.io.*;
import javax.swing.*;
public class TestChooser extends JFrame
public TestChooser()
    final JFileChooser fC = new JFileChooser(); //Final modifier needed
                                //because this object is used in an inner class.
    fC.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    JButton button1 = new JButton();
    button1.setText("Activate File Chooser");
    button1.setBounds(50, 50, 50, 50);
    button1.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        int returnVal = fC.showDialog(TestChooser.this, "Attach");
        if(returnVal == JFileChooser.APPROVE_OPTION)
          File curDirectY = fC.getCurrentDirectory();
          /* The "Look In:" Label information is being returned,
             instead of the complete directory & folder details
             contained in "File Name:". Note that File Name has the
             keyMnemonic of underscore N.
          String str = curDirectY.toString();
          System.out.println("Of course the selected Directory is "+str);
    this.getContentPane().add(button1);
public static void main(String args[])
    JFrame frame = new TestChooser();
    frame.setBounds(100, 100, 300, 200);
    frame.setVisible(true);
}I have noticed that the "File Name:" section has a Key Mnemonic of N so maybe that can be used in the actionListener, I'm just not sure how. If anybody can help me with retrieving the information from the "File Name:" section as opposed to the "Look in:" section it will be greatly appreciated.
Regards
Davo

<snip>
File curDirectY = fC.getCurrentDirectory();The above method is the wrong method to call. It returns the directory that the JFileChooser itself is pointing at. It knows nothing about what file or directory may have been selected. Use the getSelectedFile() method instead.

JFileChooser question regarding the order of the files in a folder

I was hoping someone had a way around this issue I am having with the JFileChooser. I have a folder that has filenames in it like text1.txt, text2.txt, and so forth all the way up to text300.txt. When the filechooser shows these files it shows the order of them as:
text1.txt
text10.txt
text11.txt
text2.txt
text20.txt
text21.txt
and so forth.
How come it doesn't list them like they would be in a folder window like:
text1.txt
text2.txt
text3.txt
text150.txt
text151.txt
text299.txt
text300.txt
Actually I know why JFileChooser does it this way, it is because it sorts them as Strings without taking into account the number at the end of a similar string.
Anyway, I was wondering if anyone had some ideas of how I could alter the JFileChooser to list the contents of a folder like this in the "right" order. Hopefully that made sense. :) Thanks.

Thank u for ur reply.... actually the thing is mine's one of the pre-ordered iphones n it's reaching me by 2moro i think. so are the pre-ordered iphone's already activated? or m i in trouble if it's not activated out of the box (if i have to activate it myself). ?

Save in JFileChooser question

Hello everyone ...
I have a problem that has many answers on this site, but i cannot understand them (damn newbie me ! :)) ).
I use a JFileChooser to save a file and I want the extension of the file to be automatically appended to the filename. I use a filter for viewing files but i don't know how can I use a filter to save the files.
Thanks in advance,
Dan

class MyExtensionFilter extends FileFilter {
String myExtension = "";
public MyExtensionFilter(String myExtension) {
this.myExtension = myExtension;
public boolean accept(File file) {
return file.getName().endWith(myExtension);
public string getDescription() {
return myExtension;
File chosenFile = myFileChooser.getSelectedFile();
chosenFile = newFile(chosenFile.getAbsolutePath() + myFileFilter.getDescription();

JFileChooser or FileDialog.... so many questions

hi all,
i have searched the forum to no avail so i need your help.
i am wanting to use jfilechooser to get the directory listing and files over a tcp/ip connection. i send the getdirectory message to the server and it returns the directory. next, i send the getfiles message to the server and it returns the files in the directory. i can get the directory by overriding the setcurrentdirectory()method but how do i set the files in the filechooser. can it even be done this way. if so, what methods do i need to override to accomplish this task. any help will be greatly appreciated
thanks

I believe JFileChooser is only for file systems that the current JVM has access to (in other words, not remote file systems).

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 refresh question

We all know that the JFileChooser is incredibly sloooooooow in sdk1.4 (especially across networks.)
Maybe someone can help me with this (sort of) workaround:
I selected a directory in the file chooser. It takes 10 mins to come back. During that time, I'd like my mouse pointer to change to the WAIT state. I can do that part, but the file chooser gives me back control before its done & my cursor goes back to the DEFAULT state.
Does anyone know how to find out when the file choose is really done?

Hi all,
thanks for your answers I just realized that I did not expalin myself clearly:
I know about the rescanCurrentDirectory method BUT I do not know how to link it in the JFileChooser diaolog interface.
The only way I figured out is to create an accessory button an add it to JFileChooser (setAccessory) BUT it looks ugly .....
Any idea ????
