User Rating: / 32
PoorBest 

The Java tip illustrates a method of implementing a progressbar in your application. The example demonstrates the JProgressBar component. The component tracks the progress of a for loop. This tip is very useful for developers who are developming the installers of their applications. Further it may also be used in those applications which require time to be executed and developer may show the progress of the task in a progress bar.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class ProgressBarExample extends JPanel {

  JProgressBar pbar;
  static final int MY_MINIMUM=0;
  static final int MY_MAXIMUM=100;

  public ProgressBarExample() {
     pbar = new JProgressBar();
     pbar.setMinimum(MY_MINIMUM);
     pbar.setMaximum(MY_MAXIMUM);
     add(pbar);
  }

  public void updateBar(int newValue) {
    pbar.setValue(newValue);
  }

  public static void main(String args[]) {

     final ProgressBarExample it = new ProgressBarExample();

     JFrame frame = new JFrame("Progress Bar Example");
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);   
     frame.setContentPane(it);
     frame.pack();
     frame.setVisible(true);

     for (int i = MY_MINIMUM; i <= MY_MAXIMUM; i++) {
       final int percent=i;
       try {
         SwingUtilities.invokeLater(new Runnable() {
             public void run() {
               it.updateBar(percent);
             }
         });
         java.lang.Thread.sleep(100);
       catch (InterruptedException e) {;}
     
  }
}
