Swing bug? cannot set width of JToggleButton

Hello,

Just wondered if this was a Swing bug. See also

bug 6349010.

The width of the JToggleButton cannot be set.

However the height can be set.

The important line is line 135 - and also 140.

Try changing the width of the button - it does not change.

thanks,

Anil
