Titled separator in java swing

Question

I want to show titled separator in java swing application. Something like

-------Text-------

I found some third party libraries providing this functionality:

• http://www.jidesoft.com/javadoc/com/jidesoft/swing/TitledSeparator.html
• http://www.jaxfront.org/member/java-core-api/com/jgoodies/forms/builder/PanelBuilder.html

But I'm interested in a way without using any third party api. Can we do this by extending JSeparator? How else can we do that?

Answer 1

I think you might be able to use a combination of a MatteBorder and a TitledBorder

MatteBorder mb = new MatteBorder(1, 0, 0, 0, Color.BLACK);
TitledBorder tb = new TitledBorder(mb, "Some Long Text", TitledBorder.CENTER, TitledBorder.DEFAULT_POSITION);

Answer 2

Use a TitledBorder. Like this for example:

import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.border.TitledBorder;

public class TestBorder {

    protected void initUI() {
        JFrame frame = new JFrame(TestBorder.class.getSimpleName());
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel panel = new JPanel();
        TitledBorder titledBorder = BorderFactory.createTitledBorder("Some title");
        titledBorder.setTitleJustification(TitledBorder.CENTER);
        panel.setBorder(titledBorder);
        frame.add(panel);
        frame.setSize(400, 300);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                new TestBorder().initUI();
            }
        });
    }

}
