Using Netbean's Desktop Application's status bar

Question

Hello everyone, I would like to know a way to actually make the status bar that is provided by netbeans when you create a desktop application work, but I don't really understand how.

I am including the code below so everyone can understand what I mean and where to find it in netbeans.

    // 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()
    {

        @Override
        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()
    {

        @Override
        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()
    {

        @Override
        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);
            }
        }
    });

I understand that ir probably has to do with the TaskMonitor but I cannot get it. :(

If you just want to update the text in the status bar, use:

StatusDisplayer.getDefault().setStatusText("Hello World!");

If you want to use a custom Component (like in your example), you need to create a new class. It will automatically register itself:

@ServiceProvider(service=StatusLineElementProvider.class, position=18)
public class TestStatusLineElementProvider implements StatusLineElementProvider {
    private JLabel statusMessageLabel = new JLabel("Hello World!");

    @Override
    public Component getStatusLineElement() {
        return statusMessageLabel;
    }
}
