I am trying to modify a widget style so that it scales widget features in 
accord with the widget font used. For example, I want the check boxes to be 
scaled up when the font size is increased.
So I'd like to use font-relative measures to calculate widget features.
An 'em' is the width of a capital M, and it should be easy enough to calculate
as fontMetrics().width("M");
for the 'ex' size (the height of a lowercase 'x'), I am currently using 2 * 
fontMetrics().strikeOutPos(), which is near to what I need, but it tends to 
give a value a bit larger than the real one. Is there a way to obtain the 
real value?

Thanks in advance,
Luciano
