java-programmer, JButton - Set font to fill Hi,

I want to create the best fitting font for my jbutton, so when the user
expands the UI, the JButton expands or shrinks, so I then change the size of
the font to fill the button correctly..

I am trying something like this on component resize:

Sorry... inadvertently sent before completion!!

Here is the code I am using:

private void handleFontRescale(){
JButton b = _buttons[0];
Dimension d = b.getSize();
Font f = b.getFont();
int size = 1;
Graphics g = b.getGraphics();
Font rescaledFont = f;
while(true){
Font newFont = new Font(f.getName(), f.getStyle(), size);
if( g.getFontMetrics(newFont).stringWidth(" ") >= d.width * 2 /
3
|| g.getFontMetrics(newFont).getHeight() >= d.height * .5){
for( int i=0; i < _buttons.length; i++){
_buttons[i].setFont(rescaledFont);
}
break;
}
else{
size++;
rescaledFont = newFont;
}
}
}

As you can see, I am setting the size to 1, then increasing it till I hit
the required size o fthe button.
The problem is that I am still getting "..." when I start shrinking the
fonts (on screen resize smaller), so I guess my calculations are incorrect
(IE: how much of the button dimension can I take up in text?

Can anyone point me in the right direction?

Steve

Just use getPreferredSize() instead of the low-level Font calculations.
