Verily I say unto thee, that Roy Schestowitz spake thusly:
Linux Version of Chrome To Use Gtk+
Google "[avoids] cross platform UI toolkits because while they may offer
what superficially appears to be a quick path to native looking UI on a
variety of target platforms, once you go a bit deeper it turns out to be
a bit more problematic." Your applications end up "speaking with a
foreign accent", he adds. In addition, Goodger claims that using
something like Qt "limits what you can do to a lowest common denominator
subset of what's supported by that framework on each platform."
So much for Matt's theories.
