JprogressBar

[cotarelo]

Hi,

I am trying to do a progress bar. I started with the netbeans java desktop application.

I dont know why but when I write:

progressBar.setValue(100);

Does not produce any results in my progress bar.

Anyone knows why?

You've got a bug. Where, I've no idea other than that it's not in the code you've posted. Again, this is where an SSCCE would help us come up with a solution quickly. Otherwise it's up to you to debug. Much luck.

wait a minute...
Is your progress bar filled up?
What you mean saying "cannot see any results"?

[cotarelo]

No, the progress bar stays there, without any visual results of any type

Here is the code, the line I am referring is in the method goButtonActionPerformed

package progressbartest;

import org.jdesktop.application.ResourceMap;
import org.jdesktop.application.SingleFrameApplication;
import org.jdesktop.application.FrameView;
import org.jdesktop.application.TaskMonitor;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Timer;
import javax.swing.Icon;

/**
 * The application's main frame.
 */
public class ProgressBarTestView extends FrameView {

    public ProgressBarTestView(SingleFrameApplication app) {
        super(app);

        initComponents();

        // status bar initialization - message timeout, idle icon and busy animation, etc
        ResourceMap resourceMap = getResourceMap();
        int messageTimeout = resourceMap.getInteger("StatusBar.messageTimeout");
        messageTimer = new Timer(messageTimeout, new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                statusMessageLabel.setText("");
            }
        });
        messageTimer.setRepeats(false);
        int busyAnimationRate = resourceMap.getInteger("StatusBar.busyAnimationRate");
        for (int i = 0; i < busyIcons.length; i++) {
            busyIcons[i] = resourceMap.getIcon("StatusBar.busyIcons[" + i + "]");
        }
        busyIconTimer = new Timer(busyAnimationRate, new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                busyIconIndex = (busyIconIndex + 1) % busyIcons.length;
                statusAnimationLabel.setIcon(busyIcons[busyIconIndex]);
            }
        });
        idleIcon = resourceMap.getIcon("StatusBar.idleIcon");
        statusAnimationLabel.setIcon(idleIcon);
        progressBar.setVisible(false);

        // connecting action tasks to status bar via TaskMonitor
        TaskMonitor taskMonitor = new TaskMonitor(getApplication().getContext());
        taskMonitor.addPropertyChangeListener(new java.beans.PropertyChangeListener() {
            public void propertyChange(java.beans.PropertyChangeEvent evt) {
                String propertyName = evt.getPropertyName();
                if ("started".equals(propertyName)) {
                    if (!busyIconTimer.isRunning()) {
                        statusAnimationLabel.setIcon(busyIcons[0]);
                        busyIconIndex = 0;
                        busyIconTimer.start();
                    }
                    progressBar.setVisible(true);
                    progressBar.setIndeterminate(true);
                } else if ("done".equals(propertyName)) {
                    busyIconTimer.stop();
                    statusAnimationLabel.setIcon(idleIcon);
                    progressBar.setVisible(false);
                    progressBar.setValue(0);
                } else if ("message".equals(propertyName)) {
                    String text = (String)(evt.getNewValue());
                    statusMessageLabel.setText((text == null) ? "" : text);
                    messageTimer.restart();
                } else if ("progress".equals(propertyName)) {
                    int value = (Integer)(evt.getNewValue());
                    progressBar.setVisible(true);
                    progressBar.setIndeterminate(false);
                    progressBar.setValue(value);
                }
            }
        });

In that monstrosity of code, you seem to have a couple of Timers. One of them is probably resetting any progress balue you set elsewhere.

No, the code like a

private void goButtonActionPerformed(java.awt.event.ActionEvent evt) {
        // TODO add your handling code here:
        progressBar.setValue(100);
    }

wouldn't work because you have to use

a) DefaultBoundedRangeModel(from,0,0,to)
b) put the progress bar filling in sep. thread. public void run(){} method
c) controll it's processing with a loop like a while()

[cotarelo]

Thanks for the reply! I am still trying but I get no results.

I declared in the class

DefaultBoundedRangeModel model = new DefaultBoundedRangeModel(0, 0, 0, 100);

then on the initcomponents

       progressBar = new javax.swing.JProgressBar(model);

and then inside the goButtonActionPerformed method

new Thread() {

        public void run() {
        int value = progressBar.getValue() + 7;
        if (value > progressBar.getMaximum()) {
          value = progressBar.getMaximum();
        }
        progressBar.setValue(value);



        }
        }.start();

It compiles without errors but it does not show progress bar.

Could you give me an example?
Thanks!

for a positive feedback of course :)
