to make text compact on JButton

Hi,

I hope to make the text on the JButton compact. This is comparable to
set the "internal margin" attribute for a Text box in the Microsoft
WORD. The default margin is none zero. If you set one of the left/
right/top/bottom to be zero, a little more text can be displayed in
one line/column when the Text box size is not changed.

I didn't find where can I set this for the JButton. The JTextComponent
has a "setMargin(Insets m) " method to achieve this. But JButton is
not a subclass of JTextComponent. JButton has setFont() method, but
font attribute doesn't seem to deal with the text line margin. Font
class itself has "getLineMetrics()". I guess it's related but there's
no "setLineMetrics" so that I can set the internal text margin.

Currently, my Button has to be certain large to display its default
font-size (12, Times new roman) text. If I shrink the button, text
will be "..." but the total button size is actually enough to display
the text, if I can set the line' left and right margin =0; Besides, I
must use "center" alignment for the text.

Anyone has idea?

Thanks
