How to Make Gtk3 Applications Look Better On Ubuntu?

Question

I Just began Gtk3 development with natty and for my first app, the Interface looks horrible.
It's like that of windows 98 Oo !
A screenshot to show you what i mean >> http://www.dumpyourphoto.com/photo/view/69642/2pnZdX I\m using the sample code from getting started with gtk.

Answer 1

This isn't a programming issue, it's a system configuration issue. You need to install a GTK3 theme.

(For best results, I'd advise installing a theme package that comprises a GTK2 and GTK3 theme, like Adwance. Otherwise your GTK2 apps will look poor instead.)

Answer 2

Report a bug/wish to Gnome3 and Ubuntu that their default Gtk theme looks horrible?
