WingDings Font Problem

I am having trouble getting any type of symbol font to display properly. I have tried both WingDings and Symbol. Currently the code I have does the following.

1 -Starts by putting the font in the defaults table for later lookup by the app

defaults.put("symbols.font", new FontUIResource("WingDings", Font.BOLD, 16));

2 - Grabs the font at a later point from the defaults table

Font symbolsFont = (Font)UIManager.get("symbols.font");

3 - Sets the font and draws some text with it


The problem is that anything drawn shows up as an open square. For whatever reason it appears not to recognize the font.

How do I remedy this problem and make sure it doesn't happen on end-users machines?

Thanks.

If you've done 1., then I'm not sure why you're calling Font symbolsFont = (Font)UIManager.get("symbols.font");
as opposed to defaults.get(). In any case are you sure that:
a) symbolsFont is holding a reference to a WingDings font
b) Your users are running Windows

I am calling the get because the setting of "symbols.font" is just something I do in the defaults for me so I can access it from other classes and not worry about changing it in 100 places if I need to.

A) I am pretty sure. I don't know how to tell but if I do a println(symbolsFont) it states  WingDings along with the attributes I set after my call to get.

B) The problem is on my development machine which is windows, and yes the users will be also.

OK. I wonder if its a CharacterEncoding problem - have you *ever* seen the WingDings appear in your Java guis?

Nope, but I haven't tried before either.

Tell me what you see on the command line when you run this:

public class WingDing {

  public static void main(String[] args) throws Exception {
    System.out.println(Class.forName("sun.awt.windows.CharToByteWingDings"));
  }

}

OK, I've had the same problem, hence the commented-out line in paint() down below. This is a mixture of a kludge and a more portable solution! The WingDingFrame is somewhat redundant - I changed my mind about what I was going to do. Please ask if you need more comment:

import java.awt.*;
import java.awt.event.*;

public class WingDing {

  public static void main(String[] args) throws Exception {
    //System.out.println(Class.forName("sun.awt.windows.CharToByteWingDings"));
    WingDingFrame wdf = new WingDingFrame("This is a test!");
    wdf.addWindowListener(new WindowAdapter(){
      public void windowClosing(WindowEvent e){
        System.exit(0);
      }
    });
    wdf.setSize(300,300);
    wdf.setVisible(true);
  }

}

class WingDingFrame extends Frame {
  public WingDingFrame(){
    super();
  }

  public WingDingFrame(String s){
    super(s);
    WingDingPanel wdp = new WingDingPanel();
    add(wdp);
  }

  class WingDingPanel extends Panel {
    public void paint(Graphics g){
      super.paint(g);
      //g.setFont(new Font("WingDings", Font.BOLD, 16));
      g.drawString("\u270E\u2702\u2701\u260E\u2706\u2709\u231B\u2328",10,50);
    }
  }

}

What were you doing with the WingDings anyway?

I am developing a program where I need to replace letters with various symbols or shapes. I'll have a look at the link and example and get back to you.

Hmmm ... it seems to work okay for displaying my wingding type fonts. But, it only works if I never call setFont() on the graphics context -- which means both my wingding characters are too small, and my other characters are in the wrong font.

Not sure why you should have a problem here. This example uses 'all' the Unicode WingDing-like symbols. You can use the table at the very least:

import java.awt.*;
import java.awt.event.*;
import java.util.Random;

public class WingDing {
  final static int STRING_LENGTH = 10;
  final static char[] UNICODE_SYMBOLS = {
    '\u2701','\u2702','\u2706','\u2707','\u2708',
    '\u2709','\u270c','\u270d','\u2713','\u2717',
    '\u271e','\u2720','\u2721','\u272a','\u2730',
    '\u2734','\u2735','\u2736','\u273f','\u2740',
    '\u2744','\u274d','\u2751','\u2752','\u2756',
    '\u275d','\u275e','\u2780','\u2781','\u2782',
    '\u2783','\u2784','\u2785','\u2786','\u2787',
    '\u2788','\u2789','\u278a','\u278b','\u278c',
    '\u278d','\u278e','\u278f','\u2790','\u2791',
    '\u2792','\u2793','\u27a1','\u27a2','\u27a5',
    '\u27a6','\u27a9','\u27b3'
  };

  public static void main(String[] args){
    Frame f = new Frame();
    WingDingPanel wdp = new WingDingPanel();
    f.add(wdp);
    f.addWindowListener(new WindowAdapter(){
      public void windowClosing(WindowEvent e){
        System.exit(0);
      }
    });
    f.setSize(300,300);
    f.setVisible(true);
  }

  static class WingDingPanel extends Panel {
    public void paint(Graphics g){
      super.paint(g);
      g.setFont(new Font("SansSerif", Font.BOLD, 32));
      /**
       * Generate random symbol string of STRING_LENGTH characters.
       * This will, of course, change as the Frame is resized.
       */
      StringBuffer sb = new StringBuffer(STRING_LENGTH);
      Random r = new Random();
      for(int i= 1;i <= STRING_LENGTH ;i++){
        int n = r.nextInt(UNICODE_SYMBOLS.length);
        sb.append(UNICODE_SYMBOLS[n]);
      }
      g.drawString(sb.toString(),10,50);
    }
  }
}

Hmm ... looks like I'll have to experiment since if I use the SansSerif font it works fine. Thanks.

Thanks. My example works equally well with a serif font actually.

Yeah, but when I specify Lucida Sans is when it doesn't work for me for a lot of the characters.
