Since BackTrack4 brings many programs using GTK + graphics libraries I think it would be cool to try to improve the look of these applications under the KDE environment.
I am no expert in KDE but searching in google I found that gtk-qt-engine-kde3 package allows you display a GTK+ app like a Qt app.
How enable this feature?
- Install gtk-qt-engine-kde3 of backtrack repos
- Go to Settings -> Appearance & Themes -> GTK Styles and Fonts
I don't know if there are any other tool like gtk-qt-engine-kde3.
