Question

The gzipped postscript A3 size master copy of the class chart is
available for download from
ftp://ftp.trolltech.com/qt/pdf/3.0/qt30-class-chart.pdf
(104K).^*
The PDF file will always be the same or more recent than the
one shown here.

^*
The PDF file is not supported; we do not guarantee it
will print correctly (although several people have reported that it
does). It is not available in any other format or size.
