문제

I have the following code:

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

          import java.beans.*;
 import java.util.Random;
@SuppressWarnings("serial")
 public class ProgressBarDemo extends JPanel

                                    PropertyChangeListener {
private JProgressBar progressBar;
private JButton generateButton;
private JButton exceptionButton;
private JTextArea taskOutput;
private Task task;

class Task extends SwingWorker<Void, Void> {
    /*
     * Main task. Executed in background thread.
     */
    @Override
    public Void doInBackground() {
        Random random = new Random();
        int progress = 0;
        //Initialize progress property.
        setProgress(0);
        while (progress < 100) {
            //Sleep for up to one second.
            try {
                Thread.sleep(random.nextInt(1000));
            } catch (InterruptedException ignore) {}
            //Make random progress.
            progress += random.nextInt(10);
            setProgress(Math.min(progress, 100));
        }
        return null;
    }

    @Override
    public void done() {

        generateButton.setEnabled(true);
        setCursor(null); //turn off the wait cursor
        taskOutput.append("Done!\n");
        JFrame newFrame = new JFrame();
        newFrame.setVisible(true);

    imgl.setBounds(10,10, 150, 70);
    //Create the demo's UI.
    generateButton = new JButton("button1");
    generateButton.setActionCommand("button1");
    generateButton.addActionListener(this);
    generateButton.setBounds(50, 200, 150, 30);

    exceptionButton = new JButton("button2");
    exceptionButton.setActionCommand("button2");
    exceptionButton.addActionListener(this);
    exceptionButton.setBounds(50, 300, 150, 30);

    progressBar = new JProgressBar(0, 100);
    progressBar.setValue(0);
    progressBar.setStringPainted(true);
    //progressBar.setBounds(x, y, width, height)

    taskOutput = new JTextArea(5, 20);

    labelpanel.setLayout(new BoxLayout(labelpanel,BoxLayout.Y_AXIS));
    add(panel, BorderLayout.LINE_START);
    add(new JScrollPane(taskOutput), BorderLayout.CENTER);
    panel.add(progressBar);
    setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));
}

    task.addPropertyChangeListener(this);

    task.execute();

        progressBar.setValue(progress);
        taskOutput.append(String.format(
                "Completed %d%% of task.\n", task.getProgress()));
    } 
}
/**
 * Create the GUI and show it. As with all GUI code, this must run
 * on the event-dispatching thread.
 */
private static void createAndShowGUI() {
    //Create and set up the window.
    JFrame frame = new JFrame("ProgressBarDemo");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    //Create and set up the content pane.
    JComponent newContentPane = new ProgressBarDemo();
    newContentPane.setOpaque(true); //content panes must be opaque
    frame.setContentPane(newContentPane);
    //Display the window.
    frame.pack();
    frame.setVisible(true);
}
public static void main(String[] args) {
    //Schedule a job for the event-dispatching thread:
    //creating and showing this application's GUI.
    javax.swing.SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            createAndShowGUI();
        }
    });
}
}

I have an image logo.jpg and text "TEST APPLICATION". I want both these in one line. WIth my above code,the image is on top and text in on next line. How should I modify this code to bring both on one line without affecting other elements present in the frame?

다른 팁

JLabels can contain both an icon, and the text, so you can simply add them both to the same label:

JLabel headerLabel = new JLabel("TEST APPLICATION", JLabel.LEADING); 
ImageIcon icon = new ImageIcon("logo.jpg","hiii");
headerLabel.setIcon(icon);

And then you won't need imgl anymore.

As a side note, don't use absolute layout. You will run in to problems with that. Use layout managers instead.
