Re: JavaFX and it use of GTK3
If you are dependent on Qt, you won't run on systems that don't have Qt either. All software has dependencies .. GTK is what core JDK uses, Swing has a GTK L, we generally have used platforms which use GTK as our core platforms, for build, test, and support. -phil.

I am running KDE which uses Qt, and apart from a very few applications I have very little reliance on GTK.
