Thread in Swing -Please help

Hi
I want to use thread in loading data in the JFrame / JInternalFrame and thus separating the initialization of the GUI.
The sample is as follows-
public class TestThreadFrame extends javax.swing.JFrame {
public TestThreadFrame() {
initComponents();
loadData();
private void initComponents() {
jComboBox1 = new javax.swing.JComboBox();
getContentPane().setLayout(new java.awt.GridBagLayout());
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
exitForm(evt);
jComboBox1.setPreferredSize(new java.awt.Dimension(150, 25));
getContentPane().add(jComboBox1, new java.awt.GridBagConstraints());
pack();
/** Exit the Application */
private void exitForm(java.awt.event.WindowEvent evt) {
System.exit(0);
* @param args the command line arguments
public static void main(String args[]) {
new TestThreadFrame().show();
// variable declare
private javax.swing.JComboBox jComboBox1;
void loadData(){
//code for loading data e.g. loading data in the JCombobox
---> Any help is appreciated.

Do you mean something like this ?
public class TestThreadFrame extends javax.swing.JFrame {
public TestThreadFrame() {
initComponents();
// loadData();
loadData l = new loadData();
l.start();
private void initComponents() {
jComboBox1 = new javax.swing.JComboBox();
getContentPane().setLayout(new java.awt.GridBagLayout());
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
exitForm(evt);
jComboBox1.setPreferredSize(new java.awt.Dimension(150, 25));
getContentPane().add(jComboBox1, new java.awt.GridBagConstraints());
pack();
/** Exit the Application */
private void exitForm(java.awt.event.WindowEvent evt) {
System.exit(0);
* @param args the command line arguments
public static void main(String args[]) {
new TestThreadFrame().show();
// variable declare
private javax.swing.JComboBox jComboBox1;
class loadData extends Thread
public void run()
{ try {
//code for loading data e.g. loading data in the JCombobox
jComboBox1.addItem("Hello");
Thread.sleep(2000);
jComboBox1.addItem("Hello2");
Thread.sleep(2000);
jComboBox1.addItem("Hello3");
Thread.sleep(2000);
jComboBox1.addItem("Hello3");
catch( Exception x ) { System.out.println(" Ooops : "+x.toString() ); }

That one's from a book. I used that code to start with my applet. Mine calls different merthod from the switch cases. Say I have:
case 0: drawStart(g); break;
public void drawStart(Graphics g){
/* something here */
drawMain(g);
public void drawMain(graphics g){
g.drawString("test", x, y);
//here's where i'm trying to pause
//i've tried placing Thread.sleep between these lines
g.drawLine(x, y, a, b);
//Thread.sleep here
g.drawRect(x, y, 50, 70);
}I also need to put delays between method calls but I need to synchronize them. Am I doing it all wrong? The application pauses or sleeps but afterwards, it still drew everything all at once. Thanks a lot!

It is. Sorry about that. Just answer any if you want to. I'd appreciate your help. Sorry again if it caused you anything or whatever. .n_n.

Exception in thread "main" - error: Please help

I installed the Java 1.4.0 beta on my machine. I configured the JRE and the javac and java commands are responding well. Now I have written very simple classes which are compiling without errors. But now, if I use the java command to run the classes, I am getting the following message:
Exception in thread "main" java.lang.NoClassFoundError: ForTick/class ;
where ForTick is the name of my class for example. Where am I going wrong? Also, where do I find documentation for error messages like this - I have toured almost the whole java website and even the documentation that I downloaded -but I couldn't find it.
Please help me coz I am just stuck.

Did you try
java ForTick.class ?
If so, please try
java ForTickHope this helps

Hi Phill.,
I have altered your code. Just a little bit. take a look.
Please do changes accordingly. And better use NetBeans IDE for developing a swing application.

Problems with swing, please help!!!

im trying to display an image made up of a set of squares.
i have a JFrame class which has the main method placing a JComponent into its Container using the getContentPane().add method.
the JComponent class sets up the image using the paintComponent() method
When i try to run the program all i get is a grey frame.
Ive looked at other threads in this forum to fix my problem but it doesnt seem to fix it.
any help is much appreciated.

Don't ask people to reply by private email. Most Forum regulars believe solving problems should be a public, transparent process during which a first try at an answer can and should be corrected if someone more knowledgeable notices that it is incomplete or incorrect. Also, they get some of their reward for being respondents from being seen to be competent and knowledgeable by their peers (not to mention the possibility of collecting some of those precious Duke Dollars).
In addition, begging (e.g. "pleaaaaaaaaaaasee") is extremely unbecoming. It's especially annoying when it's coupled with vagueness about the actual problem. Go read the finj - mini-howto. If you have trouble writing the code, come back with specific questions.

Newbie to swing, please help

http://forum.java.sun.com/thread.jsp?forum=57&thread=382447&tstart=75&trange=15
above is a link to my source code,
I having difficulties of structuring code when it get large.
The programs should work from 1.3 to 1.4 at least.
Now the problem is, when doing all these stuff in the code, it works what
I expected.
But when i seperate them into several classes, and extending JPanel,
strange things happen, I do not need to implement listener anymore.
And Gridbaglayout stuff cannot resize. At least I do not know how to.
thankyou for help

sorry, i do not know the meaning of 'format code'.(no offense)
As I have copy the stuff from a java enviroment call drjava, so i thought
they should be format, and I have test it by pharsing the stuff from the forum back to drjava and window text editor, they both work.
My code problem was
1. Have a class call KineWorld, can compile and work when all code inside.
2.When I seperate the code into 5 more classes, Create(4 different name) and a class call Film which extend serializable.
3.The four classes Create... was to create four panel which, put into cardlayout in KineWorld.
4.(problems)All four panel now extend JPanel and don't need implement listeners.
Plus all panel now cannot resize(It like it was on another rigid panel).
The source code actually was not expected to read all through, they are far too long, I expect them to be compiled and give a general idea to the helper of what i am doing.
The only code to be examined should be where the class extend JPanel, and the main class KineWorld where the four created panel added.

See page 47 of your User's Guide "Recovering the Internal Storage Drive". The instructions are very detailed and complete and also outlines your various choices. Follow those directions PRECISELY.
Windows 7 Starter is the edition of Windows your notebook came with and that you have been using and that will be there when you recover the HDD.

First things first. Next time please use the code formating tags when posting your code.
Secondly, we cant help you do your entire project or more specifically we cant do it for you. We can probably help you with one section at a time.
Thirdly, do not post your entire code. Create a Short, Self Contained, Compilable Example (SSCCE) that demonstrates the problem section, and that is independent of any third party libraries and can compiled instantly and tested.
Now, lets see if we can answer one problem here.
Ques 1. In the form I have one JComboBox of Country and other of State. Now I want it in such a way that whenI select a country from the Country JComboBox ,the corresponding states automatically appears in the State JComboBox.
Ans 1: Use an ItemListener or an ActionListener (javax.swing.event) for this. Once an item is selected, the event will be fired and then you populate your ComboBox with the requried data.
Ques 2. I need to add picture frame in the 6th tab so that the picture shows up when clicked browse and open.
Ans 2: You haven't created the JButton for the browse action, nor have you created the JLabel to show the picture in. Create the JButton, then the JLabel, attach an ActionListener to the button to listen for the button click, open a JFileChooser, select the image file, create an ImageIcon and pass the File object returned to it. Then call the JLabel.setIcon( the ImageIcon) to display the picture. You'll have to store the picture File information some where so can reference it when saving.
Ques 3.I need to add tables in 1st and 5th tab which shows up the details through database when added through several textboxes and combo boxes.
You need to do some reading. The Swing Tutorial has everything you need, from How to use Tables to How to connect to databases. There are also some examples in your JDK installation folder, ie, jdk/demos/jfc/tableExample. Here is the link to the swing tutorial on how to use Tables: http://java.sun.com/docs/books/tutorial/uiswing/components/table.html. You find other useful links there.

Cannot Import javax.swing.JOptionPane Please HELP!!!

import javax.swing.JOptionPane;
this line of code returns the error:
C:\Java Files\BankAccount\BankAccount_Test.java:1: Class javax.swing.JOptionPane not found in import.
import javax.swing.JOptionPane;

1 error
Process completed.
Please help, I don't know what the problem could be....

Swing was not part of any JDK's earlier than 1.2. Swing (or anything with a J in front of it, ie. JFrame, JOptionPane, etc...) was probably the most dramatic (if not largest) modification/addition to the Java language, that's why versions later than, and including, 1.2 are known as "Java 2".

Change of Business Area to Cost Center (my first thread , please help)

Hi Everybody i'm Charmaine Leena Martin freshly certified FICO consultant , this is my first thread i'm posting, please help me with the same.
A wrong business area has been assigned to a cost center and postings have taken place in the same.
while using t-code KS02: change cost center , for rectifying the business area , i get the following error:
"Field change business area is not possible (transaction data exists)"
so i've created a new cost center and assigned it the right business
and using t-code kb61 : i have posted the documents to the new cost center
at that time system generates a co-document automatically:
But the accounting document of which transfer postings have taken place still shows old business area and cost center
Please let me know why is it so ,
and what has to be done with the CO document that gets posted automatically
and is there any other way out of changing the business area without creation of new cost center
Moderator: Please, search before posting

Hi Leena
Welcome to SDN
Do KB11N to post the cost back to the Wrong cost center
Do an FI Posting again Dr the Correct new cost center and Cr the Old wrong cost center
This will match both FI and CO

Please help!! how to compile/run Swing

Hi all! please tell me how can I compile and run Swing classes in
Forte.
I have a window frame (WindowA class)that calls another window frame(windowB class)
They are stored in the same directory but saved with different name.
Please help..
thanks in advance

oh i just read your other post. you can call another class simply by
just writing
newClass x = new newClass();
or just :
new newClass();
works i think :)
put that line in the actionPerformed method,
and if newClass() has a frame, it'll come up in a new window.
You did handle the button with an ActionListener right?

Threading issue (please help)

In my code in response to an event, I send off a message to the server and wait for the appropriate response. For some reason, my listening thread stops until the my waiting function has timed out, no matter how long I wait. I'll get all server messages the second the thread finishes. I am letting the "wait" thread sleep, so why am I getting the deadlock? Please help
Here's my code:
public boolean waitForIQ(String id, int tries){
int timeOut = 0;
while(tries > 0){
while(iqTrigger == false){
//System.out.print("Waiting...");
iqTrigger = false;
timeOut++;
if(timeOut == 30) return false;
Contact.threadSleep(200);
if(lastIQ.id.compareTo(id) == 0){
return true;
}else{
tries--;
return false;
here's threadSleep:
public static void threadSleep(int time){
try{
Thread.currentThread().sleep(time);
}catch(InterruptedException e){
e.printStackTrace();
here's the listening thread:
public class SocketListener extends Thread{
public SocketListener(){
public void run(){
while(true){
XML xml = new XML(receiveMsg());
}

When the XML object is created, the trigger is set to true, but this doesn't ever happen because I don't receive the messages while waiting. The thread that's sitting there ONLY checking for messages will totally stop until my waitForIQ has timed out, then it'll process all the messages I've received.
For whatever reason, my listening thread's waiting on my waitForIQ thread to timeout and my waitForIQ threads waiting on a message that the listening thread SHOULD receive. So, they're going into temporary deadlock until the waitForIQ thread times out.
