How to access all fonts of a font family with Swing

Question

My installation of OS X 10.8 comes pre-installed with 11 fonts in the family Helvetica Neue. I'm trying to find a way to access the fonts with styles like medium or condensed, which cannot be represented by the bit-mask values Font.BOLD and Font.ITALIC.

GraphicsEnvironment.getAllFonts() returns Font objects for all these fonts but applying them using JLabel.setFont() seems to only use the styles representable with the mentioned bit-mask. This is shown on the left in the screenshot below, which compares it to a sample of all fonts when they are used in TextEdit.

The same happens if a Font object is constructed using the font's full name or its PostScript name.

Is there a way to use all those fonts, either by applying it to a Swing component or when painting to a Graphics2D (or Graphics) instance?

Output from the Swing application on the left, sample of all fonts on the right.

Below is the code I used to produce the dialog in the above screenshot.

package fahrplan;

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

public class FontsMain {
    public static void main(String[] a) {
        GraphicsEnvironment e = GraphicsEnvironment.getLocalGraphicsEnvironment();

        JPanel contentPane = new JPanel();
        contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.PAGE_AXIS));

        for (Font i : e.getAllFonts()) {
            String name = i.getFontName();

            if (name.startsWith("HelveticaNeue")) {
                JLabel label = new JLabel(name);

                label.setFont(i.deriveFont(18f));

                contentPane.add(label);
            }
        }

        JFrame frame = new JFrame("Fonts");
        frame.setContentPane(contentPane);
        frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}

I would do it like this.

int size=12, style=0;

GraphicsEnvironment e = GraphicsEnvironment.getLocalGraphicsEnvironment();
final Font[] fonts = e.getAllFonts();
for(int i=0; i<fonts.length; i++)
    {
        JLabel label = new JLabel(Font[i].getName);
        label.setFont(new Font(Font[i].getName, size, style));
        contentPane.add(label);
    }

I hope this helps.

The only difference in your code that I can spot right now is that you use a font size of 12 pt instead of 18. I don't think that's making a difference. ;) On a second note, did you look at the screenshot in my question? – Feuermurmel Mar 22 '13 at 15:55
I believe you! I since found out that this only happens for fonts for which multiple styles are stored in the same `.dfont` file, which us unique the OS X. I'm still looking for a way to use all those styles on a Mac. – Feuermurmel Apr 02 '13 at 12:21
This actually does not compile. First of all, Font[i] is not going to work, you probably mean fonts[i]. Also, the correct constructor is Font(name, style, size). In your code, the style would be set to 12 and size is set to 0. Thirdly, this is not an answer to the question. – Mo'in Creemers Nov 21 '22 at 10:37
