L&F for JFileChooser

When I show an open file dialog, its L&F is set back to the windows default. The components inside of it still have the Java L&F but the dialog itself is still windows. I didn't find a JFileChooser.setDefaultLookAndFeelDecorated() method :-). Please help.
Regards,
Igor

The method is rather JDialog.setDefaultLookAndFeelDecorated(true)

How can I set a default file for JFileChooser

Hi. I am developing a p2p chat application and I have to unrelated questions.
1. How can I set a default file name for JFileChooser, to save a completly new file?
2. I have a JTextArea that I append recieved messages. But when a message is appended, the whole desktop screen refreshes. How can I prevent that?
Hope I was clear. Thanks in advance.

Thank you for the first answer, it solved my problem. Here is the code for 2nd question, I've trimmed it a lot, hope I didn't cut off any critical code

Is there any way to get preview of word,excel as accesory for JFileChooser?

i want to set an accessory for jfilechooser so that i can preview documents file or any media files using the setAccessory method of JFileChooser.
Will it can be done by Runtime.getRuntime.exec() as an win32 api method so that it can open the file in the accesory of jfilechooser or in jFrame instead of another window.
Plz anybody have any idea's.

That's correct...itune's app store will always prompt you to update. Hopefully Apple will change this policy!

Need help for JFileChooser

Hi,
I need help on this one. I have a filechooser class which extended from JFileChooser class. Every thing works fine except this: I want to by hiting the "Enter" key to save the files. The "Enter" key works only when the focus is in the file name text field now, I want it to work when the focus is in the directory area, the file list area and the file type area as well. I try to add the KeyListener but how can I get hold of the component of the three areas of file chooser? I tried to add the KeyListener as Accessory, it didn't work either. Some one please help me.

Try this to let your components react to ActionEvents
comp.addActionListener(new WhatIWantToDo());
// WhatIWantToDo is the inner class.
// Let it do what you want to be the reaction
class WhatIWantToDo implements ActionListener {
public void actionPerformed(ActionEvent event) {
// code on what you want to do
}Or working without an inner class try this
comp.addActionListener(new ActionListener() {
// the event handling
public void actionPerformed(ActionEvent event) {
// your code for behavior
// e.g. System.out.println("There is a reaction");
// or specify a special named component as c1
Object source = event.getSource();
if (source == c1) doSomething();
else if (source == c2) doOtherThings();
});Hope this is of help for what you want. Else let me know.

Generating virtual files for JFileChooser by implementing FileSystemView

Hello,
I'd like to display in a file hierarchy using JFileChooser component of data that I'm fetching from the database. From what I read thus far, I'll need to implement the FileSystemView and FileView abstract classes to generate virtual files on the client. There was also a reported bug for sdk 1.4.1_01 stating that subdirectories could not be viewed when running the JFileChooser. Does anyone know if this bug has been fixed in 1.4.1_02, and could anyone post some sample code how to implement these classes?
Thanks a lot,
Ariela

helpdid you read the examples in JFilechooser Tutorial?
all you have to do is modify to it.

Getting current directory for JFileChooser

I'm trying to construct a JFileChooser that uses the current directory as its view (and not the default Windows "My Documents" directory path). How can I get the current directory path? File definately doesn't have anything, Toolkit neither.

I had the same exact question a while ago. The solution is quite simple.
JFileChooser j = new JFileChooser(".");

Enhanced JFileChooser for file encoding selection

In many I18N applications, files are stored in different encodings, including Unicode formats. It would be very useful for JFileChooser to have a file encoding selection mechanism similar to that in MS Windows' common file dialogs -- the "Encoding" box can be seen in Windows 2000/XP Notepad's File Open/Save dialog, directly under "File name" and "Save as type" combo boxes.
This enhancement will make JFileChooser closely match Windows standard file dialogs and be a desirable option on other platforms as well.
Vote for Bug Id 4935601:
http://developer.java.sun.com/developer/bugParade/bugs/4935601.html
(also posted in Internationalization Forum)

That is a good point! I think all of documents encoded in Unicode need this feature to be saved correctly.

How do I rewrite current code for java 1.3

I'm using the code below that is written for java 1.4. I have been told that the company can not push JRE 1.4 to the company, and that I need to write my code for java 1.3. I'm using org.w3c.dom for my create xml, etc.
Is there a java 1.3 option to the 1.4? Any help would be very appreciated.

Are there features of Java 1.4 that you specifically took advantage and are there any particular lines you are having problems with or did you just freak and post it here?
Basically compile it under Java 1.3 and see what complains. I've done several projects that compile under 1.2, 1.3, and 1.4.

JFileChooser, multiple dialogs.

My JFileChooser is getting the path and filename for a file, to be later opened. I'm placing the path and name in a JTextField.
My problem is this: whenever I click 'Find' and select my file and click 'Open', the path and filename show in the JTextField, but the dialog reopens as though I'm pressing the 'Find' button again.
Here's my source:

The problem is with he registration of actionListener for the find button.
This is being done in your code each time the AddNewItem is being
used. because of this each time you click Add New Item. another listener
is registered for the find button and hence the no. of times it will
show filechooser will keep on increasing.

How do you add a combo box into a Jfilechooser?

how do you add a combo box into a Jfilechooser?
thanks

See the API For JFileChooser
public void setAccessory(JComponent newAccessory)Extend a JPanel or Such like, put your Combo Box on it, fiddle around with event handling code for the ComboBox..
Set an Instance of that as The Accessory for the JFileChooser.
Look In Your Docs:-
<JAVA_HOME>/Demo/jfc/SwingSet2/src , unpack SwingSet2.jar if neccessary
In there is a demo of using A JFileChooser with an accessory Panel, and Source code that is adaptable...

JFileChooser Network Folder Issue

Hello all
Class : javax.swing.JFileChooser (network folders)
J2SE : 1.4
OS : Windows
I'm in need of urgent help for JFileChooser, scenerio is, currently when I do a open or save dialog using the JFileChooser it brings up the mapped network folders along with local folders on my PC.
For selection, if I clicked on the network folders, is there a way I could differentiate if it was one of the mapped network folders or a regular file on the file system? I dont see any of the folders underneath my network folder, it just doesnt seem to work right.
Also the mapped network folder is username password protected which comes up with the Username Password prompt dialog the first time I access it through the open / save dialogs, where exactly does it store this information.
Any help would be highly appreciated.
Regards

I'm assuming that we are still talking about mapped network drives
under "My Computer", as opposed to navigating "Network Neighborhood"
and using UNC paths.
Are you saying that, in order to know if its a network folder i have
to search for " on " in the display name, and if its a web folder
search for a ".", in order to determine if the difference. Is this the
only way I could determine if its a network / web folder as compared
to the local folders on my PC :(
I was looking in for some kind of property that would help me determine it.I still don't understand where you want to test for this. Do you have
a listener on the JFileChooser to catch directory changes, or did
you set it up to only select directories, or are you talking about
determining this after the user has chosen a file?
No, there is no way in Java to determine whether a path that starts
with a drive letter is in fact a mapped network folder. My suggestion
was pretty ugly, as I said. I don't understand what you mean by "web
folder". JFileChooser doesn't support URL paths. If you mean UNC paths
then just test for f.getAbsolutePath().beginsWith("\\\\").
Also why dont I see the directory structure underneath the webfolder
or network folder from my JFileChooser?If the folder is not currently mapped because it requires a password
or the host is not responding, then JFileChooser will display an empty
folder. We may look into fixing this in a future release.
One last thing: For password protected web folders, when I select them
through my JFileChooser, the "Enter Network Password" window pops up,
and this happens only once in the applications lifetime, I presume its
storing this information somewhere, do you have any idea where exactly
i should be searching for these values? I didn't see this dialog pop up from JFileChooser until the new 1.4.2
release that we're working on. In any case, it is handled by the
operating system and our code knows nothing about it. I'm sure there
is no way to ask the operating system for stored passwords as that
would compromise security.

JFilechooser Problem

Hi,
i have 2 problems with filechooser(jdk1.4.2)
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 ..
Regards
Ganesan S

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:

JFileChooser Win2000 Vs XP Look GUI in 1.4.1

I observe that with 1.4.1 the JFileChooser has most of the Win 2000 File Chooser functionality, however when this same code is run on a Win XP environment I get the older(1.3.1) JFIleChooser UI, with a lot odf the functionlity (that is now provided in 1.4.1 with the 2000 env )missing.
Please confirm that this is caused becuase the Java 1.4.1 native implementation for JFileChooser does not support XP or is this becuase I'm missing something in my code. Are there work-arounds so that the solution provides similar Look and feel in both Win2000 and Win XP.
Thank you for your time.

At the beginning of your main add the lines :
    public static void main(String[] args) {
                System.setProperty("os.name", "Windows 2000");
          System.getProperty("os.version", "5.0");
          try {
               UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
          catch (Exception ex) {
               System.out.println(ex);
    }I hope this helps,

JFileChooser functioning like normal Windows Apps FileChooser

I have this problem that's been giving me too much headache already. When you click on Open on any Windows app, and click on the "Details" button, it will show you the files' details (FileName, Type, Date, etc.). This is the same with JFileChooser, so no problem there. The thing is, with Windows apps, you can click on the headers and have the files sorted according to the header you clicked. This doesn't happen to a JFileChooser. Has any of you guys did this or found any solution to this problem? I've searched (almost) everywhere, Google, Sun, etc., I even looked into JFileChooser's source code but I can't seem to find anything.
I know this is possible, so anyone who can help, you'll be greatly appreciated.

Thought I would pass along some updated code for this as this was very helpful to us as we are still on jdk 1.5.
This has been modified to use the Windows UI. The advantage of doing this in the UI class is so you can set it as the default UI for JFileChooser inside your application. If you had this as a subclass of JFileChooser (as it is above) then you explicitly have to use that subclass throughout your application. By setting this UI class as the FileChooserUI in your UIDefaults table then every instance of JFileChooser will now automatically use your overridden UI and theres nothing else you have to do.
