How to change font of a GroupComponent?

How can we change the font used by GroupComponent?  It doesn't have setFont().  I also looked through LookAndFeel, and while it has many getXXXFont() methods, none of them are for GroupComponent.




It isn't the content of the group I need to change, it is the "label" at the top of the groupbox I'd like to change.  For example, the S 2 5/16" and R: 2 5/16" in this screenshot.  I'd like to use a monospaced font like the content uses.

Isn't it a case of overloading LookAndFeel::drawGroupComponentOutline() ?
