FileChooser problem

Hello,
I have a problem with filechooser filter. I read the documentation and I can set the filter. But I have 2 problems with it.
1. Directorys are not visible.
2. User can select the "All files" option too. But I don't want to allow it.
What can I do?
Thanks!
My code is:
        class MyFilter extends javax.swing.filechooser.FileFilter {
            public boolean accept(File file) {
                String filename = file.getName();
                return filename.endsWith(".java");
            public String getDescription() {
                return "*.java";
        String filename = "";
        File f;
        JFileChooser fileChooser = new JFileChooser(new File(filename));
        fileChooser.addChoosableFileFilter(new MyFilter());
        fileChooser.setFileSelectionMode(javax.swing.JFileChooser.FILES_AND_DIRECTORIES);
        fileChooser.showOpenDialog(parent);

1) in accept, includeif file.isDirectory() return true;2) callfileChooser.setAcceptAllFileFilterUsed(false);

JFileChooser Win32

Hello,
I have read about the startup time problem with JFileChooser. Also in my company many people say 'Swing is slow', because they know, that the filechooser is slow. And this results in the view, that those people change to SWT.
Because I know, that Swing is fast enough for all, I want to solve the filechooser problem. As found in the bug database (6372808), I add the following line to my install program:
regsvr32 /u %windir%\system32\zipfldr.dll
This works fine for the zip file problem under windows.
But I have also watched, that the filechooser needs still 1-3 seconds to be opened. I have created a JNI for OS specific functions and added file selection into it. The user can select 'native dialogs' in my application properties and than the windows standard file dialog is used.
I hope, I can help a lot of people with this problem. If somebody is interested, send me an email.
Best regards,

Figured it out, thanks to another post.
I added
player.stop():
to my playerClose() method.
Seems to work fine now.
//=======================================================
// Close player and deallocate

public static void playerclose()
player.stop();

Displaying the path of the file selected by a FileChooser in a TextField

I'm just getting started with Swing. I developed a simple dialog box that has two text fields and two buttons. The objective is to open two files using those two buttons. I used FileChooser to select the files. Now, I want to display the path of the selected files in their corresponding TextFields. I use the following code to do that.
final FileChooser fc1 = new FileChooser();
final FileChooser fc2 = new FileChooser();
final TextField tf1 = new TextField();
final TextField tf2 = new TextField();
private void button1ActionPerformed(ActionEvent evt)
            int returnVal1 = fc1.showOpenDialog(labelPhpFile);
            if (returnVal1 == JFileChooser.APPROVE_OPTION)
                File file1 = fc1.getSelectedFile();
                String fileName1 = file1.getName();
                String filePath1 = file1.getPath();
                tf1.setText(filePath1);
private void button2ActionPerformed(ActionEvent evt)
            int returnVal2 = fc2.showOpenDialog(labelPhpFile);
            if (returnVal2 == JFileChooser.APPROVE_OPTION)
                File file2 = fc2.getSelectedFile();
                String fileName2 = file2.getName();
                String filePath2 = file2.getPath();
                tf2.setText(filePath2);
}The above code works fine only for the first file. Mean the path of the file selected using fc1 is getting displayed in the tf1 TextField. But, the file selected using fc2 is not getting displayed tf2 TextField. Please help me.
Thank you :)

Using a filechooser in an applet

Is it possible to use a filechooser for an applet save button? If so how can you do it? So far I have only been able to use the filechooser object with JFrame and not JApplet.

Hi,
I'm a newbie, but I just had a similar problem and the solution was in the html code to display the applet. here's the code:
<applet width=700 height=500 code="ImageExample.class"> </applet>
make sure the height and width here are big enough for your imaage.

Deployment problems that I don't know how to fix or trace - Please Help

I have made a javafx application in netbeans where I import classes from the java library (specifically ones from java.io for writing/readning files). The program works great in the IDE, reading and writing files, but when I build it and run the .jnlp, It does not write any files or do anything that requires any of the imported functions. I have been trying for a few weeks now and have had no luck. The same thing happens when I create a brand new javafx desktop application and try to make it write a simple text file.
My questions are these:
1. Does someone know if I'm missing something? I tried checking the box that makes it a self signed jar and pack200 compression, no luck. This program is for running locally on the user's machine.
2. I do not no how to check for exception traces the application may have thrown. I am using Mac OSX 10.6.6, and the latest Java and Netbeans. Can someone help me with this?
My deadline is coming up and I don't want to rewrite the whole thing using something else. I was pleased with this javafx application until now. Please Help
here is my test .fx file

Hello user,
You can see the traces of your application from java console which will automatically appears when your application is running on browser. In MAC OSX the java console icon appears at top right bottom (tray icon) and you can view the console from their.
Please trace the exception what you have got so that we could find the real problem.

How to get the full path instead of just the file name, in �FileChooser� ?

How to keep filename in textfield when filter is changed in a filechooser

Hi, guys,
I met a problem to keep filename in textfield when filter is changed in a filechooser
for example, a JFileChooser has two filters
*.jpg
*.png
Before I open JFileChooser, I used setSelectedFile(File) to set "aaa.jpg" as default name in textfield.
when I change the filter to "*.png, ", I want to change the text in textfield to "aaa.png", Actually, I used setSelectedFile(File), If there is an existed file named "aaa.png", this file will be selected on fileView, but the name will not be shown on the textfield. Anybody has ideas?
Thanks in advanced.

I really thank you for your answer, but it seems you misunderstand what I said because of my poor english..
what I said is:
after you open the filechooser, the filechooser has a combobox to choose file filter and a field to show filename.
what I want is:
when you open the filechooser, initial name in field is "test. jpg"
change filter, "test.jpg" will be change to "test.gif" in the field.
I don't want to close the filechooser.
That's why I used a listener to listen JFileChooser.FILE_FILTER_CHANGED_PROPERTY event.
and I modified your codes

Help! File in use problem when using Swing app

Hi. I got a program that is pretty much a JFileChooser that prints to standard output the path of the file that I've chosen. If I invoke the DOS command:
java JFileChooserDemo, I will get the following as expected from the program:
"You chose a file named: C:\MyJava\Book.xls".
But if I invoke the following DOS command:
java JFileChooserDemo > output.txt, the file "output.txt" contains the following:
"GetModuleHandleA succeed
LoadLibrary returns baaa0000
You chose a file named: C:\MyJava\Book.xls"
So, if I try to open the file or try to modify "output.txt", I get an error message stating that the file is in use.
What's weird is that, I THINK if I have a program that DOES'NT use Swing or anything GUI-related and prints to standard output with the DOS "> outfile" command, I won't get this problem. So in other words, I can duplicate this problem with a sample Swing application that prints to standard output. Try it yourself.
In my original program, it does have an event handler that closes the JFileChooser and its container and exits the system via "System.exit(0);", but for some reason, something still has "locked" the output.txt file. I even did the ctr+alt+del and can't find anything that would lock the output.txt file. What's even weirder is that if I run the application again, but output to a different file like "output2.txt", this file is not locked, but the "output.txt" file still is. output2.txt also don't have contain the
"GetModuleHandleA succeed
LoadLibrary returns baaa0000" message.
The only way I know of that would "unlock" output.txt is to re-boot my computer.
So it seems I have to modify my program somehow because it appears the OS still thinks output.txt file is still in use.
Someone may think why would I invoke the java interpreter with the DOS "> outfile" command. Well, the reason being, I got a different version of the program that executes a query and I want it to create a delimited text file that contains the resultset of the query, so that I can then import it to Access, Excel, or whatever. But, because of this problem, I can't modify the query result without having to either run the application again and created another file name with the same result or re-boot. Of course, this would be silly.
Any help in how I can modify my program or any GUI-program so that if I invoke the DOS "> outfile" command, the outfile won't be "locked" would be greatly appreciated. Thanks. If you want my program, you can e-mail me or run any sample program from the Swing Tutorial that prints to standard output and just add the " > outfile" to the java interpreter command.

So it seems I have to modify my program somehow because it appears the OS still thinks output.txt file is still in use.
Someone may think why would I invoke the java interpreter with the DOS "> outfile" command. Well, the reason being, I got a different version of the program that executes a query and I want it to create a delimited text file that contains the resultset of the query, so that I can then import it to Access, Excel, or whatever. But, because of this problem, I can't modify the query result without having to either run the application again and created another file name with the same result or re-boot. Of course, this would be silly.
Any help in how I can modify my program or any GUI-program so that if I invoke the DOS "> outfile" command, the outfile won't be "locked" would be greatly appreciated. Thanks. If you want my program, you can e-mail me or run any sample program from the Swing Tutorial that prints to standard output and just add the " > outfile" to the java interpreter command.

Problem with JFileChooser when run using Netbeans

I just want to state that I have NO problem writing the code that brings up this component. My problem is what happens when the JFileChooser component is loaded. My environment is Windows Vista, Java SE 1.6.0. -> Netbeans IDE 5.0. The code I use is as follows:
public RegexParser()
JFileChooser openfile = new JFileChooser();
openfile.showOpenDialog(RegexParser.this);
int returnVal = openfile.showOpenDialog(RegexParser.this);
if (returnVal == JFileChooser.APPROVE_OPTION)
//This code gets the path of the file and uses as a parameter to parse data.
filename = openfile.getSelectedFile().getPath();
openfile.setVisible(false);
ParseData(filename);
The problem is when I try to select an option from the combobox labeled "Look In:" Every directory I select which is not the root of the drive will display NO FILES even though there are files in that directory.
Notice: I have also run the same code using the cmd.exe and it works fine. I have also looked at: http://java.sun.com/docs/books/tutorial/uiswing/components/filechooser.html but have found nothing that has helped me.
Can someone explain what is the problem? Is this a known bug in Netbeans? Is there any code that can be used as a workaround?

Yes I copied the code to my machine and run it. The example program had problems when I executed using netbeans it had the problem.
When I executed using Command Prompt there where no problems.

Problem in JFileChooser

I have got a problem here. Here I have a JFileChooser, I want to add in
a FileFilter, and user could only see some type of file. But as long as I
try to get the extension....It wont compile, could any one teach me how
to get the extension of a file in JFILECHOOSER???
============================================
import java.io.*;
import java.io.File.*;
import javax.swing.filechooser.FileFilter;
public class MainFrame extends JFrame implements ActionListener {
public MainFrame() {.............}
private boolean chooseFile()
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileSelectionMode( JFileChooser.FILES_ONLY );
FileChoser filtering = new FileChoser("txt");
fileChooser.setFileFilter(filtering);
fileChooser.addChoosableFileFilter(filtering);
int selection = fileChooser.showOpenDialog( this );
if ( selection == JFileChooser.CANCEL_OPTION )
return false;
if (selection == -1) {
return false;
File tmpfile = fileChooser.getSelectedFile();
filename = tmpfile.toString();
setTitle( "Smiggin Holes 2010 - " + filename );
return true;
static class FileChoser extends javax.swing.filechooser.FileFilter
String extension;
String description;
public FileChoser(String extension, String description){
this.extension = extension;
this.extension = description;
// Accept all directories and all gif, jpg, or tiff files.
public boolean accept(File f)
if (f != null)
if (f.isDirectory())
return true;
String ext = getExtension(f); //<<<<<<<<<<<THE PROBLEM IS HERE WHEN I TRY TO GET THE EXTENSION OF THE FILE. IT CANT COMPILE
System.out.println("aasdfasdf"+ext);
if ((ext!=null)&&(ext.equals(extension)))
return true;
return false;
// The description of this filter
public String getDescription() {
return "Just Text Files";
======================================
Could you tell me what can I do? To get the extension of the file selected by the user?
And What do I have to change?
Regards,

Hi !
in the FileChoser class, the public boolean accept(File f) method can be written like this :
public boolean accept(File f) {
if (f.isDirectory || f.getName().endsWith(".txt")) { // you can add other extensions
return true;
else {
return false;

Renaming a file in a filechooser

renaming a file in a filechooser -
Single click or right click on a folder of a JFileChooser allows you to edit the new file name ina textfield. When the focus is lost from the text field the folder name is changed to the older one. But after editing the file name in the textfield and press 'Enter' the folder or file is updated with the new name. Can anybody tell me if there is a way to make it work on loosing focus ???
Thanks in advance

This sounds like a bug from the install. I use Mavericks and do not have this problem. I suggest reinstalling: http://support.apple.com/kb/PH13871

File chooser internationalization problem

Hello All!
I'm trying to have Armenian texts on Swing components.
        Locale hay = new Locale("hy", "HY");
        Locale.setDefault(hay);
        UIManager.put("FileChooser.openDialogTitleText", "Բացել");
        UIManager.put("FileChooser.saveDialogTitleText", "Պահել");
        UIManager.put("FileChooser.lookInLabelText", "Փնտրել");
        UIManager.put("FileChooser.saveInLabelText", "Պահել");
        UIManager.put("FileChooser.upFolderToolTipText", "Մի Մակարդակ Վերև");
        UIManager.put("FileChooser.homeFolderToolTipText", "Աշխատաէկրան");
        UIManager.put("FileChooser.newFolderToolTipText", "Ստեղծել Նոր Պանակ");
        UIManager.put("FileChooser.listViewButtonToolTipText", "Ցուցակ");
        UIManager.put("FileChooser.detailsViewButtonToolTipText", "Մանրամասներ");
        UIManager.put("FileChooser.fileNameHeaderText", "Անուն");
        UIManager.put("FileChooser.fileSizeHeaderText", "Ծավալ");
        UIManager.put("FileChooser.fileTypeHeaderText", "Տեսակ");
        UIManager.put("FileChooser.fileDateHeaderText", "Փոփոխման Ամսաթիվ");
        UIManager.put("FileChooser.fileAttrHeaderText", "Հատկանիշներ");
        UIManager.put("FileChooser.fileNameLabelText", "Նշոցի Անուն");
        UIManager.put("FileChooser.filesOfTypeLabelText", "Նշոցների Տեսակներ");
        UIManager.put("FileChooser.openButtonText", "Բացել");
        UIManager.put("FileChooser.openButtonToolTipText", "Բացել Ընտրված Նշոցը");
        UIManager.put("FileChooser.saveButtonText", "Պահել");
        UIManager.put("FileChooser.saveButtonToolTipText", "Պահել Ընտրված Նշոցը");
        UIManager.put("FileChooser.directoryOpenButtonText", "Պահել");
        UIManager.put("FileChooser.directoryOpenButtonToolTipText", "Պահել Ընտրված Նշոցը");
        UIManager.put("FileChooser.cancelButtonText", "Դադարեցնել");

        UIManager.put("FileChooser.newFolderErrorText", "Նոր Պահոցի Ստեղծման Սխալ");
        UIManager.put("FileChooser.acceptAllFileFilterText", "Բոլոր Նշոցներ");Only DialogTitleText is working. And if I'm trying to internationalize other Swing components: buttons and so on, the only problem with JFrame title is.
I'm working on WindowsXP, and java version is 1.6.0_17.
Thanks in advance!

The quick answer:
You can't use JFileChooser unless you sign the applet.
