How To Change Width of QWhatsThis

I'm not sure how to change the width of the QWhatsThis box that shows up when QWhatsThis is enabled. I am displaying HTML in there and it is splitting words onto two lines instead of one. Can anybody help?

Have you tried using <nobr/> or using a table with a width set?

thanks, I had no luck with the <nobr /> tag, but the table width worked.
