I\'ve just started porting my Swing app from OS X to Windows and things are painful with JLabels.

I\'ve noticed that the font specified to setFont

    For reference, here's what is seen on Mac OS X.

    enter image description here

    By comparison, here's the display on Ubuntu 10, OpenJDK 6.

    enter image description here

    import java.awt.Font;
import java.awt.GridLayout;
import java.io.File;
import javax.swing.*;

public class LabelTestFrame extends JFrame {

    public LabelTestFrame() throws Exception {
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setLayout(new GridLayout(0, 1));
        String fontPath = "SophomoreYearbook.ttf";
        Font testFont = Font.createFont(
            Font.TRUETYPE_FONT, new File(fontPath)).deriveFont(18f);
        JLabel label1 = new JLabel("<html>Some HTML'd text</html>");
        label1.setFont(testFont);
        this.add(label1);
        JLabel label2 = new JLabel("Some plaintext");
        this.add(label2);
        this.pack();
        this.setLocationRelativeTo(null);
    }

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

            @Override
            public void run() {
                try {
                    new LabelTestFrame().setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }
}

    registerFont()

    I found this little gem while Googling about if I could copy a .ttf into the JRE at runtime. It does exactly what it's supposed to. If you use Font.createFont to load a font at runtime, just do:

    GraphicsEnvironment.getLocalGraphicsEnvironment().registerFont(myCreatedFont)

    to register it with the JRE.

    This allows the font to show up in HTML'd text as well as plaintext on Windows!
