I also check for platforms (sketch up code... not tested)

QFont f;
#ifdef __WIN32__
f.setFont(QFont("Courier New", 8));
#else
f.setFont(QFont("Monospace", 10));
#endif
QFontMetrics fm( f );
 int pixelWidth = fm.width( "00" );
widget->setFixedWidth( pixelWidth + 10 ); // leave out some margins

Do you want to query the list of fonts, and see which one of them is fixed?
