Label on JButton is too small

In the following code I display 4 buttons. When I run it, the two smaller buttons display 3 boxes which I think is equivalent to three dots meaning there isn't enough room to display the text. The two larger buttons display my tiny little symbol (which is a solid black triangle) correctly.

Looking at the two smaller buttons there is obviously plenty of room to display this tiny symbol. The three boxes being displayed instead are way larger.

Can anyone see what I'm doing wrong? Can I increase the size of the button label without increasing the size of the button? Or maybe there is some way to tell java to just display the string without displaying three dots if it thinks it doesn't fit?

I don't know if this problem is related to the font itself but Webdings is a standard font on Windows 98/2000/ME/XP which is where I'll be running this code.

Here is an example. Thanks for looking!

package testwebdings;

import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Font;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class TestWebDing {
   
    public static void main(String[] args) {
        new TestWebDing();
    }
   
    TestWebDing()
    {
    Font dingFont8 = new Font("webdings",Font.PLAIN,8);
    String upTriangle = (new String(new char[]{(char)0xf035}));
    //
    JButton button30 = new JButton(upTriangle);
    JButton button40 = new JButton(upTriangle);
    JButton button50 = new JButton(upTriangle);
    JButton button60 = new JButton(upTriangle);
    //
    button30.setPreferredSize(new Dimension(30,30));
    button40.setPreferredSize(new Dimension(40,40));
    button50.setPreferredSize(new Dimension(50,50));
    button60.setPreferredSize(new Dimension(60,60));
    //
    button30.setFont(dingFont8);
    button40.setFont(dingFont8);
    button50.setFont(dingFont8);
    button60.setFont(dingFont8);
    //
    JFrame controlFrame = new JFrame("Test WebDings");
    Container content = controlFrame.getContentPane();
    JPanel panel = new JPanel(new FlowLayout());
    content.add(panel);
    //
    panel.add(button30);
    panel.add(button40);    
    panel.add(button50);
    panel.add(button60);
    //
    controlFrame.setBounds(0,0,400,100);
    controlFrame.setVisible(true);
    } // end ctor
} // end class

the 3 boxes sound more like that font doesn't have a defined symbol for the that character.
Check you are using the right character(s).

or it could be the font doesn't have a symbol for the "." (indicating not enough room).
try increasing the preferred size for the button

I know it is defined because it shows up on the two larger boxes.

>> or it could be the font doesn't have a symbol for the "." (indicating not enough room).

Yes, that is exactly right - it is the period which is not defined. But I don't want to make the button bigger. There seems to be plenty of room, the symbol is very small, much smaller than the three boxes that are being displayed.

using a border that uses les space (or no border at all) may also give you some more space

button30.setBorder(null);

>> button30.setBorder(null);

That was interesting - apparently it is related to the border, now the symbols are showing up, even when I make them normal size which is good. The only problem is I don't have buttons anymore, just the symbols hanging in mid-frame! Is there some way to have a border without having it take up so much room? Or perhaps there is another way to clue the user that this is a button?

BTW, thanks for your help so far. I think that border comment was a mjor breakthrough.

It didn't occur to me to mention it before but I'm using the windows look and feel. I'm now trying to figure out how to turn it off and see if that helps.

Also, I found this in reference to a similar sounding (but not the same) bug.

"You can manually set the toolbar border to use a compound border, where the inner border is empty and is set to use the
appropriate top,left,bottom,right padding"

I'm trying to figure out what that means. Is that something that could apply to a JButton?

OK, I finally changed to the motif plaf and the button sizing is much more rational so I think this might be a bug in the windows plaf.

Anyway, I'm going to try to figure out this compound border idea since I really do need the windows plaf.

This worked!

    Border bb = button30.getBorder();
    EmptyBorder eb = new EmptyBorder(-20,-20,-20,-20);
    CompoundBorder cb = new CompoundBorder(bb,eb);    
    button30.setBorder(cb);  

Thanks for pointing out the border!
