I’m running the beta1 of elementaryOS (http://elementaryos.org), so far I’m loving it! 😀 but, as you might know, I use Qt4 for my developments and I happen to like a lot of apps written with this framework, the problem is that eOS doesn’t have the qt4lib installed by default and when you install it and run any Qt app it looks like total crap. Like going back to Gnome 1.0. And you can get an error saying that “QGtkStyle was unable to detect the current GTK+ theme”.
You can solve this with this following command:
gconftool-2 --set --type string /desktop/gnome/interface/gtk_theme elementary
Yay! Now you can enjoy your Qt Apps in eOS 🙂
