the program is developed with Java 6. It seems JLayer is not
available. If I'm wrong, could you provide some code on how to do
this?
could you provide some code on how to do this? --- > JLayer & JProgressBar by @aterai, for more ideas see his blog, for Java6 you can to use JXLayer
or with very similair logics by using GlassPane

some notes
should be used GBC instead of NullLayout
can be nicer with added Icon or transparent background
(by add LayoutManager to JLabel) there can be placed bunch of JComponents with the same effect as for JPanel
for example
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JProgressBar;
import javax.swing.JRadioButton;
import javax.swing.UIManager;
//https://mcmap.net/q/1467516/-jprogressbar-low-values-will-not-be-displayed
public class ProgressSample {
private JFrame frame = new JFrame("GlassPane instead of JLayer");
private JLabel label;
private GridBagConstraints gbc = new GridBagConstraints();
private JProgressBar progressSeven;
public ProgressSample() {
frame.setLayout(new FlowLayout());
frame.add(new JButton("test"));
frame.add(new JCheckBox("test"));
frame.add(new JRadioButton("test"));
// Nothing is displayed if value is lover that 6
JProgressBar progressSix = new JProgressBar(0, 100);
progressSix.setValue(2);
frame.add(progressSix);
// but this works value is higher that 6
progressSeven = new JProgressBar(0, 100);
progressSeven.addComponentListener(new ComponentAdapter() {
@Override
public void componentMoved(ComponentEvent e) {
label.setBounds(
(int) progressSeven.getBounds().getX(),
(int) progressSeven.getBounds().getY(),
label.getPreferredSize().width,
label.getPreferredSize().height);
}
});
progressSeven.setValue(7);
frame.add(progressSeven);
label = new JLabel();
label.setText("<html> Concurency Issues in Swing<br>"
+ " never to use Thread.sleep(int) <br>"
+ " durring EDT, simple to freeze GUI </html>");
label.setPreferredSize(new Dimension(label.getPreferredSize().width, label.getPreferredSize().height));
Container glassPane = (Container) frame.getRootPane().getGlassPane();
glassPane.setVisible(true);
glassPane.setLayout(null);
glassPane.add(label, gbc);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
e.printStackTrace();
}
ProgressSample dialogTest = new ProgressSample();
}
}
EDIT
my first thought was using html, but astonishingly (for me) the
progressbar doesn't support it ... by @kleopatra
and
I think my question may not be clear enough. I don't want the text to
exceed the JProgressBar borders. Plus, I don't want to insert manually
line returns (ie no
). I added a picture of what I want. by
@Maxbester
- result is to use
JProgressBar as Container, put there proper LayoutManager, overlay JProgressBar by JLabel
![enter image description here]()
- enhancements, to set
EmptyBorder for JLabel, e.g. label.setBorder(new EmptyBorder(15, 15, 15, 15));
![enter image description here]()
EDIT2 (Icon is, can be semi_transparent too, can overlay JProgressBar)
![enter image description here]()
code could be something like as
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JProgressBar;
import javax.swing.UIManager;
import javax.swing.border.EmptyBorder;
public class JProgressBarWithJLabel {
private JFrame frame = new JFrame("JLabel in JProgressBar");
private JLabel label;
private JProgressBar progressSeven;
public JProgressBarWithJLabel() {
progressSeven = new JProgressBar(0, 100){
@Override
public Dimension getPreferredSize() {
return new Dimension(300, 60);
}
};
progressSeven.setValue(38);
progressSeven.setLayout(new BorderLayout(5, 5));
label = new JLabel();
label.setHorizontalTextPosition(JLabel.CENTER);
label.setVerticalTextPosition(JLabel.CENTER);
label.setBorder(new EmptyBorder(15, 15, 15, 15));
label.setText("<html>I have already changed the JProgressBar's height "
+ "to be able to write the text on two lines but I don't want "
+ "to the change the width.</html>");
progressSeven.add(label, BorderLayout.CENTER);
frame.add(progressSeven);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
try {
for (UIManager.LookAndFeelInfo laf : UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(laf.getName())) {
UIManager.setLookAndFeel(laf.getClassName());
}
}
} catch (Exception e) {
e.printStackTrace();
}
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
new JProgressBarWithJLabel();
}
});
}
}
EDIT3:
default stripping for WindowsClassicLookAndFeel (Icon isn't semi_transparent)
