Java SE (Java Platform, Standard Edition)

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
