How to setToolTipText for a file in jfilechooser?

I want to set tooltip text for a file in jfilechooser for getting its detail to user without selecting a file as it is in windows explorer(e.g for file size,date modified).
Since jfilechooser does not give directly reference to a file without clicking the file.
As i have found after googling that jfilechooser displays file in JList.
So here is the code that get file in JFileChooser
private Component findJList(Component comp) {
    if (comp.getClass() == JList.class) return comp;
    if (comp instanceof Container) {
        Component[] components = ((Container)comp).getComponents();
        for(int i = 0; i < components.length; i++) {
            Component child = findJList(components);
if (child != null) return child;
return null;
where in findJList jFileChooser object is passed
So i wan't to know is there any way so that the child being a file will be able to show tooltip for displaying file size or file details or any thing about File.
Please give me any solution.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

Silly me!
The simple fact that the URL isn't null, means the file exists. No need to explicitly check it again.

  • How IE works for  flat file

    Hi all:
         As we all know that, when IE gets a idoc's service name from SLD, then use it with idoc's message type and Idoc type to do receiver determniation, what about flat file ? how can we know its Service name and interface name  if there is only a flat file on FTP?  how IE works for Flat file ?
         Couldn't thank you more

    Hi,
    For any idoc scenarious, you would use business systems rather than business service which is stored in SLD. So the IE would fetch it from SLD at runtime.
    For file based scenarious also, you can create business system as type third party and use the same.
    Is that answer your question?

  • How to search for a file and copy it to somewhere else in terminal

    So basically how can I search for a file on my computer named "testingtesting.txt" and copy it to my desktop using terminal? I have very little experience in terminal, so I was going to try and use the mdfind command, then store that output as a variable, and use that variable as the source for the cp command, but I feel like there is probably a much simpler method. So basically how could I find a file named "testingtesting.txt", copy it, and paste it to my desktop using terminal.

    Is there any particular reason that you must use Terminal?
    You could just download the free EasyFind from the App Store and find the file quickly. Do whatever you wish with it.
    Good luck,

  • How to search for a file?

    Hi I am currently using the below code to detect a file automaticaly in a thumbdrive. So currently I have to state the path directory to detect the particular file. Is there a way to search for the file in the thumbdrive using Java?
    public class Detect {
    public static void main(String[] args)
    File f = new File("f:\\");
    while (! f.exists())
    try { Thread.sleep(500); }
    catch (InterruptedException e) {}
    System.out.println("drive inserted!");
    }

    You'll need to recursively search through a top directory and all its subdirectories for all files. Here is a link how to do this.
    http://www.javapractices.com/Topic68.cjp
    You can search for all drives A through Z for the file (using something like new File("F:") and catching the exception if not found (and dont do anything with the exception). But exclude C and D drive since they are usually hard drives and take forever to search through. Also, you may want to use File.separator instead of '/" or '\' in your code since windowsXP uses one while Unix uses the other and you would want your code to be able to run on either operating system.
    Are you building a web page with this? if so, it will not work since your search code would be running on the server and not on the client's machine. Even if you were able to run it on the client machine via his browser, you cant because of security reasons (end users dont want to give you access to thier drives). If its a web page, look into file upload html tag called <input type="file". This allows the end-user to navigate on his machine to where the file is and download it without you having to search for it.
    If you writing an application instead of a web page, I think there is an applet you can use that will do the same thing as <input type="file".
    Searching though a directory structure isn't good since it takes too long for users t wait.

  • How to configure for music file loading

    I don't know if you can help with this one.
    If so, great. If not, I'm not insulted.
    I have a pair of Oakley Thumps, which are sunglasses with a built in MP3 player.
    I used to have little if any problem loading music on to them from my old windows based Dell computer, by way of the Media Player.
    We just got our mac last Sunday (G5 - Tiger version of OS-X), and today was the first day that I hooked up my Thumps. The mac recognized them as Thump 128 (for the memory size) and there is an icon on my desktop. However, the files that were stored were changed to a document file, and now won't play. I tried loading iTunes songs, but they won't play, since they are MP4 (Thumps only play/recognize MP3, WMA and WAV files).
    Do you have any tips for how I can go about configuring iTunes, or any other program on my wonderful new mac, to allow me to load songs onto my Thumps?

    You will not be able to put (or play)purchased music files onto the device but you should be able to "drag" any .mp3 file onto it.
    If you mount the device and double click to open it there may be a folder structure that needs to be followed.
    The current files may be in Media Player format (.wma) and can be opened with the WMP for Mac.

  • How to search for a file at application server?

    Hi,
    I need to choose one file for further processing from the directory, located into 'WORK' directory at application server. As far as I see, class CL_GUI_FRONTEND_SERVICES and FILE_OPEN_DIALOG woudn't help me - it's a 'FRONTEND_SERVICES'.... and work with directories at presentation server.
    The requirement is that the user has no file sharing from his local PC to the mentioned directory at application server - this directory is visible only in the scope of the application server. I need something as flexible as CL_GUI_FRONTEND_SERVICES=>FILE_OPEN_DIALOG, if exist.
    How can I achieve this?
    Any help would be highly appreciated.
    Many thanks in advance.
    Regards,
    Ivaylo Mutafchiev

    Thanks to all contributors!
    After short testing I found the following:
    1. F4_DXFILENAME_TOPRECURSION is not what I was looking for - it doesn;t behave as expected.
    2. FM EPS_GET_DIRECTORY_LISTING would help if I need the result into an internal table (thsi would be a case too), but it doesn;t prompt for selection. Helpful, anyway.
    3. /SAPDMC/LSM_F4_SERVER_FILE is the closest match to the requirements.
    Thanks to all.

  • How to SEARCH for specific file TYPES, e.g. PDF?

    If I know the title has in it "resume" and I know it's a PDF, how do you search for all PDF files that have the word "resume" in the title?
    AND..
    How would you search all PDF files that had the word "supervisor" inside the document?
    Thanks

    Command F should do it. Once the search window appears, you should see a drop down box headed kind and next to it one headed any. Select PDF from the any one. Click the plus button, and another field will appear and you can see again more drop down boxes. You just want to set these up so you end up with name and contains, you can then add your text to the remaining field.

  • How to search for all files w Metadata mismatch?

    I Upgraded recently from LR2.6 to 3.3.
    Many of my images have an Exclamation Mark on them, following the upgrade, informing me that there is a Metadata Mismatch...
    When I click on it I get this Dialogue box:
    Firstly I think LR developers are playing with potentially important information with a lack of care and consideration. I looked at the metadata in 'File Info' in Photoshop before clicking anything: the creation date was the date the file was created and much of the camera data was missing. After I clicked Overwrite Settings all the original data was back on the file. I have no idea how this came to pass exactly, but it shows metadata is an easily lost thing.
    If Adobe care about their customers I would think they would make it more clear what was at stake here!
    Secondly I would like to know if there is a way to search for all images with this issue to save me having to go through and do it one by one, possibly thousands of times?

    I am not sure what the meaning of different values in column sidecarStatus and externalXmpIsDirty mean. This is what I've found out by trial and error:
    sideCarStatus = 1 seems to mean "Settings have changed in Catalog compared to XMP"
    sideCarStatus = 7 seems to be OK
    externalXmpIsDirty = 1 seems to mean "Settings have changed in XMP compared to Catalog"
    sideCarStatus = 1 AND externalXmpIsDirty = 1seems to be a Metadata Conflict
    The meaning of sideCarStatus > 1 is unknown to me
    I usually run the query and then look at the single images reported in LR.
    IMHO, this metadata matching is one of the weaker points in LR. I have encountered several conflict situations where I can be 100% sure I have not changed anything on the image outside of LR, and I have "Automatically write Changes to XMP" active. So a conflict should never arise.

    Whether you are searching for a particular file or searching within all the files then putting 10,000,000 file in a single directory looks (to me) to be silly!
    If you just want to find a particular file then why not build an index (say in a simple database). If you want to search within all the files then some directory tree structure will stop Java having to load into memory the whole of your directory content.

  • How to search for movie files on harddrive?

    Saw today in Lions new layout under "This Computer" that my harddrive contains 147GB (out of 320 GB) of movies.
    Is there any clever way to track those movie files.
    The movie files are probably spread all over the computer. I have for instace made a great deal of Final Cut clips
    that tend to be saved in several copies spread in different folders. Besides that, I probably have film and film clips in every imaginable file format that have been saved and forgotten through the years :-) (my iMac is from -07) 
    Any clever tips highly appreciated - Need more space!!
    /Friss

    The Finder can do this for you.
    Just open a Finder window and hit Command-F
    Then, in the search bar set the 'Kind' to 'Movie'.
    Done. It'll find all the movie files on your disk which you can then organize as you see fit.

  • How to show Chinese named file with JFileChooser

    I have a simple java code that could open a file and copy it to another directory. My problem is that if running it with a Chinese Windows 2000 OS, when select "File Open" and try to locate the file from a folder, the files with Chinese name could not be properly displayed. The weired part is that if you choose the Chinese named file, it could be shown correctly in the file name panel.
    When my application starts on a Chinese WIN2000 OS, saw warning as "Default charset GBK not supported, using ISO-8859-1 instead"
