There's also a large repository of software that isn't switching. "Won" implies the war is over; that Qt has earned a monopoly on Linux (or at least the de facto standard) but that's not the case here. At least not yet, maybe in a few years - though I can't see that either personally.
Maybe I'm just being pedantic, but "won" seems a little too optimistic. Particularly on a platform that's famed for it choice / fragmentation (depending on which side of the fence you sit hehe).
It also implies that there was actually a war, and that there is now not. Did gtk+ suddenly stop being developed because Qt won some imaginary war dreamed up by people who don't develop either toolkit?
Wow, I didn't expect people would read so much in my poetic language.
Qt used to be relegated to KDE on Unix but is now also used by Unity and LXDE. People prefer using Qt because it is much more cross platform friendly than GTK+ and has great developer tools. Qt seems to be the future of the Linux desktop at this point. So excusez-les-mots.
