NetBeans JFileChooser visualization problem

I have a visualization problem when i implement a JFileChooser. I use
Windows XP with SDK 1.3.1 and Netbeans 3.3
I insert a JFileChooser from the Form Editor in NetBeans but when i run my
application the JFileChooser appear in the background without waiting to be
called by an event generated by a button. When you after press the button
it works correctly; so it is only a visualization problem....
How is possible to make it hide until the pressure of that button ???
Thankyou for the help

I solved the problem by myself....-:)
I added the jFileChooser to the JFrame.
It is instead to add it out of the jFrame with "others components"

    Hi,
    For the Raspberry Pi, tooling over serial port is not supported. The simplest solution is to use standard IP networking over Ethernet. This can be a direct connection between the PC and the Raspberry Pi, as long as the cable is twisted and the IP addressing is correct (e.g. manual IP addressing or DHCP server on the PC).
    Regarding "Connecting to a UART Device": This is meant for attaching and controlling serial devices from the Raspberry Pi, not for tooling connections between the Raspberry Pi and the PC.
    Hope this helps,

  • JFileChooser hanging problem

    I am developing an application in which I use JFileChooser. It was working for a while and then (after a recent new application instal) it started to hang every time it attempted to execute the line
    JFileChooser fc = new JFileChooser();
    I tried creating a trivial new application, tried stepping into the library code and tried re-installing NetBeans 4.1 - all with no success.
    Can you suggest what else I might try?

    Thanks for the suggestion. I had not tried printing before and after so I tried it as follows:
    I put the following lines:
    System.out.println("starting new call");
    JFileChooser fc = new JFileChooser();
    System.out.println("ended new call");
    iand I got the following when I ran it:
    nit:
    deps-jar:
    compile:
    run:
    starting new call
    I then had to interrupt the process because it hung and I got:
    Java Result: 1073807364
    I had already tried it with the debugger and stepped into the code invoked by the call to new JFileChooser(). It eventually reached the Toolkit function getDefaultToolkit and never successfully returned from there. It repeatedly executed the test
    if (toolkit == null)
    as false and went straight to the final line
    return toolkit;
    Stepping on or trying to step out of that function simply returned execution to the function's opening line:
    if (toolkit == null)
    This appears to loop.
    I had a problem with Star Office not long before this problem surfaced. It reported that it had failed to save a file as I closed the application. Since it is Java based (and I am ignorant of whether there could be interference) I wonder whether that could have resulted in an overwrite of something in NetBeans. That was why I tried a re-instal - but with no beneficial effect.

  • Cover borwser & Visualizer problems

  • NetBeans 4.1 Problem

    Well, the good news is that I got my bot working (hurrah!).
    The bad news is that I can't open my JAR >< !!! (angry face).
    I know that a lot of people have had this problem and posted here about it, but I couldn't find a good answer to this question. The problem is that when I build my project and open my JAR it says "Failed to load Main-Class manifest attribute from [directory]." Yet when I extract my JAR I get a folder that contains the manifest.mf file.
    If this helps, this is the contents of my manifest file (when opened with notepad):
    Manifest-Version: 1.0
    Ant-Version: Apache Ant 1.6.2
    Created-By: 1.5.0_04-b05 (Sun Microsystems Inc.)
    I'm not sure what a manifest file should look like... and I'm not sure if this is even part of the problem... just in the other threads I visited people posted the contents of their manifest file =p
    So, do I need to reinstall/install something? I'm pretty sure I have the latest of everything, but if I have to install something, what would that be? And if not, then what's the problem?

    Well, one of the problems I had is I made a project with existing source files biaccident so I couldn't edit the Main class file. I made a new project and my my JAR semi-works. The one remaining problem is that it doesnt show my image. How do I fix this? When I run it via NetBeans it DOES show my image...

  • JFileChooser weird problem (Help!!!)

    Does anyone here have loading problem with JFileChooser?
    I have a class that inherited the JFileChooser class and another class that inherited the JFrame class and this class create an instance of the JFileChooser class.
    My program sometime will not show (but sometime will: no changes at all) and they are no exception being shown on the console window what so ever. I can solve my program by initializing the JFileChooser object after showing the application and not before but that stupid JFileChooser is so slow to initialize. What the hell is going on? Any help hint would be appreciated.

    I also want to add that the following code is in my JFileChooser class:
    protected JDialog createDialog(Component Parent)
    JDialog CustomDialog=super.createDialog(Parent);
    CustomDialog.setLocationRelativeTo(Parent);
    CustomDialog.setResizable(false);
    return CustomDialog;
    Aside from the abnormally, I don't not what else could be causing the problem!

  • JFileChooser language problem

    Hi,
    I have changed the various text fields of the JFileChooser to my language,
    e.g. UIManager.put("FileChooser.fileNameHeaderText", "string"); but i'm
    facing a strange problem. When the JFileChooser opens and i select the Details view, everything seems OK and the text is depicted correctly in my language, such as the name, date and the other columns. But when i change a folder, e.g. when i select the C:\ folder or when i press the Desktop button, the language of the text in the columns changes back to the English language. The other text fields, i.e. File type, ok button text etc are depicted correctly in my language. Does anyone know where is the problem?

    If something like this happens, then all of the JFileChooser fields shouldn't be changed to the OS language? Why only the columns text of the details view? By the way, i want the text fields to retain the names that i give, no matter the OS language. I don't want to remove any language from the OS since this is a customized solution and i want my application to run in every OS independently of the installed language.

  • New itunes 8.0  Visualizer problem

    I've been using my visualizer on the new itunes and it freezes when i try to exit or i skip songs. My laptop is brand new bought it three weeks ago so i don't think it could be the problem. I was wondering if this is just a bug the developers didn't notice?

    I also realized that if you connect your ipod to your computer when the visualizer is running it freezes itunes and you need to close it but force.

    I had the same "is not a known entity type" error when running under a development environment Eclipse/Tomcat using Toplink. But the almost same code and configuration worked when running under Eclipse as a stand-alone Java app.
    Eventually I figured out (actually trial and error), that I had checked the toplink-essentials.jar libraries to be exported under: Eclipse Project/Java Build Path/Order and Export. I was messing around with libraries. Unchecking the export option there fixed the problem.
    While its unlikely that this could have been your exact problem, I would check the library order and export configurations. Looking at other message boards about this problem, many seemed to have been caused or fixed by playing with their libraries.

    I faced the same problem, most probably you need to append \axis in your URL.

  • JFileChooser visibility problem

    Hi,
    I have a problem with JFileChooser-component. Every now and then the JFileChooser-component won't come visible and the application hangs.
    For example:
    import java.io.File;
    import javax.swing.JFileChooser;
    public class Main {
        public static void main(String args[])
             JFileChooser fcSaveAs = new JFileChooser();
             fcSaveAs.setSelectedFile(new File(fcSaveAs.getCurrentDirectory() + File.separator + "test.pdf"));
         int saveResp = fcSaveAs.showSaveDialog(null);
         if(saveResp == JFileChooser.APPROVE_OPTION) {
              System.out.println("true");
    }So, I want to give the user a sample filename, which he/she can use to save a file.
    But if I run that, every fifth or sixth time the dialog won't come visible and the application hangs. The user can't do anything but stop java.exe.
    If i take that line 8 off, system works fine. But I want to give a sample filename to the user, which he/she can use to save the file.

    Hi,
    Have you tried running on the Event Dispatch Thread (as you always should with Swing code)?
    import java.io.File;
    import javax.swing.JFileChooser;
    import javax.swing.SwingUtilities;
    public class ChooserTest {
        public static void main(String[] args) {
         SwingUtilities.invokeLater(new Runnable() {
             @Override
             public void run() {
              JFileChooser fcSaveAs = new JFileChooser();
              fcSaveAs.setSelectedFile(new File(fcSaveAs
                   .getCurrentDirectory()
                   + File.separator + "test.pdf"));
              int saveResp = fcSaveAs.showSaveDialog(null);
              if (saveResp == JFileChooser.APPROVE_OPTION) {
                  System.out.println("true");
