I'll defer to Thiago on best practise, but I had a bash at Qt versions of
the treeview and profile drawing a few days ago.
https://github.com/amitkc/diveprofile
https://github.com/amitkc/qss-divelist
Both should compile (divelist was developed on Linux; diveprofile on OS X)
and perform a limited set of the required functions. They are based on
examples taken from Qt texts written by ex-Trolls, so hopefully the
starting point is sensible (possibly not optimal).
At the very least they may help highlight gaps to direct attention to if we
are to consider dumping cairo/pango.
BTW - suggestion of continuing to use the latter to draw and then blit to
screen is very interesting.
The qwt project sources may be worth a look to see how they have done their
support for technical charts.
