How to change gap in swing label

Question

I create some label:

leftLabel.setAlignmentX(Component.CENTER_ALIGNMENT);
leftLabel.setFont(new Font(FONT, Font.PLAIN, 280));
leftLabel.setBorder(BorderFactory.createTitledBorder("aaa"));
leftLabel.setText("0");

which look like this: enter image description here

As you can see there are big gap up and down. How I can reduce it ?

What when you don't pick a font size I can read from a mile off? — MarioDS, Apr 14 '12 at 22:06
I try: leftLabel.setVerticalAlignment(JLabel.TOP); leftLabel.setVerticalTextPosition(JLabel.TOP); leftLabel.setAlignmentY(TOP_ALIGNMENT); leftLabel.setBorder(BorderFactory.createEmptyBorder(-3 /*top*/, 0, 0, 0)); but still with no success — hudi, Apr 14 '12 at 22:47

You need to tweak the border insets,

import java.awt.Component;
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.Insets;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.SwingUtilities;
import javax.swing.border.TitledBorder;

public final class TitledBorderDemo {
    private static void createAndShowGUI(){
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLayout(new FlowLayout());
        frame.add(new TitledLabel(String.valueOf(0)));
        frame.pack();
        frame.setVisible(true);
    }

    private static class TitledLabel extends JLabel{
        private static final long serialVersionUID = 1L;
        private static final String TITLE = "aaa";

        TitledLabel(String text){
            super(text);
            setAlignmentX(Component.CENTER_ALIGNMENT);
            setFont(new Font("Arial", Font.PLAIN, 280));
            setBorder(new TitledBorder(TITLE){
                private static final long serialVersionUID = 1L;

                @Override
                public Insets getBorderInsets(Component c, Insets insets){
                    // arbitrary insets for top and bottom.
                    return new Insets(insets.top - 45, insets.left, insets.bottom - 55, insets.right);
            }});

        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable(){
            @Override
            public void run() {
                createAndShowGUI();             
            }
        });
    }
}

enter image description here

Hopefully this gets you started in the right direction!

the problem is probably within the properties of the newly created border. These borders have insets. That is the only thing I can think of to influence the gaps. Try to call a method on the border that changes these insets to [1,1,1,1].
