I don't think it really matters what font the system is using, as long 
as that font is available.  I'm using DejaVu Sans at the moment, but I 
understand that if that is not available, the system will substitute a 
similar one.

I think I already know that, as on my Ubuntu, QtDesigner shows a Ubuntu 
font, whereas on Mint it shows DejaVu.

But, I'll have a look at that anyway.  It certainly now looks that both 
are using the one I coded in.  The measurements from the calculations 
are identical, although there is a very slight, barely noticeable 
difference in the QTableWidget->columnWidth() version.  I'll try to find 
why, I hope.  Different QT versions?
