JFileChooser
Hello, well i am having problems understanding how JFileChooser works with the java.io.*; package. i am trying to open a document either with .doc or .txt extentions, but also add it to a JTextArea. but i have not idea of how to get the reading file working correctly and certainly i do not have an idea on putting it in the JTextArea object. i have read the io java package link in www.java.sun.com, but i did nbot understand it very well. can you help me solve this problem and give me a link that explains the io package better.
You completely miss the point....it's ONLY function is to present a directory structure which allows you to navigate and open a file. It does NOTHING with the file except let you ascertain the name, directory, extention of the file.
Anything else having to do with the file is handled by other controls.

No Disk Error when opening JFileChooser
Hi all
After launching my app via JWS and opening my apps FileChooser I get a 'javaw.exe - No Disk' error message:
'There is no disk in the drive. Please insert a disk into drive A:.'
This doesn't happen if I start the app without JWS. Although it happens only the first time after opening the FileChooser it's rather annoying for the user. I can't expect the user always having a disk in their drive.
Is there a way of switching the scan for drive A off?
Thanks for your help.

This is a SecurityManager - Problem and the java.io.File.
eg.:
System.setSecurityManager(new RMISecurityManager());
File[] roots = File.listRoots();
Then you will see the problem...
I tried the following workaround:
before you access disk. (or JFileChooser)
SecurityManager sm = System.getSecurityManger();
System.setSecurityManager(null);
// disable the SecurityManger
// this special disk access needs no SecurityManager..
... popup JFileChosser or make FileAccess..
System.setSecurityManager(sm);
// restore the old SecurityManger
It's not the best solution but it works..
hope this will help,

Can not sort the files in JFileChooser if the files are from remote machine
Hi All,
Let me set the context of the question.
I have extended the JFileChooser to support the listing/view of files.dirs etc of remote location through CORBA.To achieve that i have customized
my FileSystemView to support it. In general ,the current JFileChooser sorts the file when we have details view .My question is related to this.The default
JFileChooser has the support for sorting but when i customized the FileSystemView,the sorting functionality is no more exist.I tried with TableRowSorter as well but
the sorting can be achieved in View only,the model still remains same as initial.
Any pointer towards this will be highly appreciated.
Thanks

JFileChooser (again!) slow in JRE 1.6.14 on some machines, not others
I am running ImageJ (from the NIH) on several of our machines and on some machines JFileChooser is lightning fast, while others exhibit the same slowness spoken of in another JFileChooser thread that is now in a locked state. We open large image files (tif, png) located on our SAN and from the network traffic I see in Windows Task Manager while opening a folder containing the images I would guess that JFileChooser is actually opening the files (intentionally or not), not just obtaining a folder listing. It's similar to the same issue of opening a large folder of images with the view set to thumbnails - it takes about the same amount of time. I have tried the suggestions in that thread to no avail - the environment the machines are running is:
Windows XP SP3
Java JRE 1.6.0_14
Can anyone comment on what JFileChooser is doing and how I can get it to stop this? Is it a Windows environment setting so that the native API calls made by JFileChooser will behave differently? Thoughts?
Thanks,
TomI can't be absolutely sure, but we have several seemingly identical machines used for the purpose of reading medical images and several of them appear to work correctly (very fast loading and population of the folder's contents) and others don't. I have been using eclipse to enhance the software tool we're using (ImageJ) and using the debugger I can see that when the JFileChooser object is being instantiated and populated with entries a tremendous amount of network traffic occurs. This network traffic is equivalent to the amount I see when the same folder is opened in My Computer using a thumbnails view of the folder contents. Apparently, the network is delivering approximately 300-400 MB of images. As far as configuration of the Windows machines is concerned I haven't found a significant difference yet, though I admit I am not a Windows desktop admin and may not know of some configuration item that could be responsible. I assume (though could be mistaken) that both My Computer and JFileChooser are ultimately using similar API calls to get the folder content entries?

Problem with JFileChooser and ImageIcon
I'm trying to create an ImageIcon object from file selected in JFileChooser. The problem is that jfc.getSelectedFile().getAbsolutePath() returns a string with backslashes and the constructor of ImageIcon requires the string to have slashes. I`ve tried to create it via URL but it doesn't work as well...
String lastUsedPath;
URL imageURL;
JFileChooser fc = new JFileChooser();
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
int returnVal = fc.showDialog(frame,title);
if(returnVal==JFileChooser.APPROVE_OPTION){
lastUsedPath = fc.getSelectedFile().getAbsolutePath();
imageURL = getClass().getResource(lastUsedPath); //don't really get this but I copied it from Java Swing Tutorial
}else{
return null;
int curH, curW;
ImageIcon srcIcon = new ImageIcon(imageURL);
curW = srcIcon.getIconWidth();
curH = srcIcon.getIconHeight();If I use it this way imageURL is set to null.
If I set the imageURL as 'fc.getSelectedFile().toURL()' the string is eg.: "file:/E:/file.jpg" instead of "E:/file.jpg". After that the ImageIcon is created but width and height return -1.
If I try to create ImageIcon by 'new ImageIcon(lastUsedPath)' I get a not null object but the width & height of the ImageIcon is -1 as well.
What do I have to do to be able to create an ImageIcon from file selected in JFileChooser? Why is this so hard and mind blowing?It still returns the ImageIcon object with width & height set to -1.
EDIT:
Got it finally:
lastUsedPathForStupidImageIcon = fc.getSelectedFile().getPath();
img = ImageIO.read(new File(lastUsedPathForStupidImageIcon));
curH = img.getHeight(this);
curW = img.getWidth(this);The key was to use another String variable and hold the path instead of the absolute path

JFileChooser animated gif preview
I'm using an Accesory with an ImageIcon to preview images on a JFileChooser.
It works ok, but I would like to know how do I get those animated gif to restart their animation whenever I click some other file (so the image preview goes to null) and click back on them.
There are non-looped gifs and looped ones, it is specially for the non-looped gifs as to give a way to get to see the animation again. After clicking the file once the animation never plays again, even if a load another preview by clicking another file and then go back...
Since there's no obvious method on ImageIcon or Image I tried flush since it says it clears the data but the only thing I got was the gif animating improperly (it would get trash/noise).

How do I change the text on my JFileChooser?
Hello,
I have a JFileChooser that is set to only select directories because... I need the user to only open directories. The problem is, whenever it comes up, in the text field at the bottom (next to the approve button) has the full path of the current directory in it. Some users are confused by this, not knowing if that text is supposed to be erased or not. Is there any way to get rid of the text so that it is a blank text field? setSelectedFile() does not work because I am using directory selection mode, not file selection mode.
Thanks for any responses,

How to make JFileChooser's directory as a droptarget?
i able to drop file in the current directory of JFileChooser (on the "look in" of it e.g look in c:\) but when i drop my file to JFileChooser any of the directories which jfilechooser shows mouse cursor shows the disable symbol which indicates that this directory doesn't support drop target i also tried for writable directory but the problem is same.
this is my code
File node = chooser.getCurrentDirectory();
// Only allow a drop on a writable directory
if (node.isDirectory()) {
try {
File f = new File(node.getPath());
if (f.canWrite()) {
return f;
} catch (Exception e) {
}i think it is the problem of chooser,getCurrentDirectory(); statement.
what should i have to place instead of this statement.
Plz help me.Note: This thread was originally posted in the [New To Java|http://forums.sun.com/forum.jspa?forumID=54] forum, but moved to this forum for closer topic alignment.

Hi All,
I am using a Frame and from this frame i am calling the JFileChooser via a JButton.
and using JFileChooser ShowOpenDialog() for open and close .
while doing ESC operation my Main Frame is getting closed with JFileChooser dialog.
Can i close only JFileChooser dialog while doing ESCAPE key operation.
I Have Escape key function in Main Frame file and JFileChooser file( EscKeyEventActionIntialization)
But while debuging i am not able to catch the esc key action inside EscKeyEventActionIntialization.
I have attached the code, please suggest me , if i need to do any change .

}You have a class that extends JDialog and has a JDialog member variable (very confusing), and no main(...) method. How is the class used as a JDialog?

Hi,
I have a File[] array (with directories and files on it), and want to take to another array the size of files only. I don't want to use File.length, because in this way i take the size of directories too.
I tried to use this:
for(int i=0; i<array.length; i++)
File f = new File(path, array.toString());
Size[i]=f.length();
}//for
but i don't think is good to have a Size array with "zeros" (when it finds directories) and long values (when it finds files).
What do you propose me to do?
Would it be good to use JFileChooser and how?
Thanks,
TSolonelWhat do you want to do with that array? Why not having a File[] array, so you have both length and isDirectory info. Sorting? Something else? JFileChooser seems irrelevant. But again, it's all up to what you are trying to do. Clarify

Problems with JFileChooser and Windows 2000 (can't see mydocuments contents
Hi! I've an applet which has a JFileChooser component. In other Windows, I can select the MyDocuments folder and it goes there and list all the contents OK. But, in Windows 2000, when I go to MyDocuments, none of the contents is listed in the file chooser. I need to navigate through all the directories to get there (C:\documents and settings\user\my documents) and then, it shows its contents, but obviously, I don't want it to be this way because is difficult for the common user.
Any idea of why is going on this?
Thanks in advance!Hello, You need to use something like o=isp as the
root DN, then o=yourorg.com goes beneath it.
i.e.
For the other questions on setup, just choose o=isp
as base DN when you set up the directory server. When
you run ims_dssetup.pl, choose o=internet as the DC
tree base, then choose o=isp as the user/groups base
suffix.
When you are installing messaging server it will ask
where to put the default organization, this is where
you would choose o=abc.com, o=isp
For more info on how this structure works please take
a look at this link and it will all fit into place:
http://docs.sun.com/source/816-6017-10/changes.htm#170

Applet with JFilechooser called from a Javascript blocks paint messages
Hi,
I am trying to create an applet that can:
1) be called from a Javascript
2) displays a file selection dialog for multi-selecting files
3) returns the selected filenames in a string to the JavaScript
I am able to use doPrivileged to apply the necessary security context to launch a JFilechooser and return the filenames selected. However, When the JFilechooser dialog is visible and the user moves the dialog window around the HTML pages dose not receive any repaint messages. They seem to be blocked by the thread that launched the JFilechooser dialog and is probably blocking update events as the dialog is still visible.
I know I need some type of a message pump so the child thread can inform the parent thread and the browser to repaint. However, I don't know how to do this.
Please help.
