These are deliberate choices: the trolls want to make the interface leane=
r
and for an outsider it makes sense, because Qt is really fat. I think
that they also have some maintainance problems with the old library.

Look at the mailling list: somebody complained about the missing raster
operation modes (Qwt uses those in QwtPicker & friends) and the trolls
asked the complainer to make his point.  We have had lots of problems
with the XorROP text drawing on X-Windows: since its introduction in
Qt-2.3 it has never worked properly (-> hard to maintain).

Maybe, if there are enough people with real examples why they need raster
operations they put it back in (there seems to be no native support for
rasterop drawing on MacOSX). Of course one can similate the XorROP mode
with a backing store, but XorROP was invented to eliminate a backing
store (it is patented http://wiki.ael.be/index.php/EnglishSWPatentExample=

-- is that the real reason for its elimination?).=20

Try it. Maybe you are lucky if you do a lot of designer stuff (designer
code must be more predictable than some of the clever tricks in Qwt).

Did you subscribe to qt4...@tr... ?

(I'll be honest: I was subscribed myself for 2 days, but I am not
 a professional programmer.  I program for mostly for fun, do not like
 complaining on lists and so I leave the complaining to professionals)
