I programmed AWT/Swing applications a lot in the past. I agree with you
that Swing programming is far more easier than SWT. But the thing of
Swing that brothers me most is that Swing application doesn't match
the look&feel on other systems than Windows. In a Gnome/GTK
environment Swing looks really ugly. Yes, I know JGoodies too, but
I want that my applications adapts the look&feel of the system.

In this sense, Swing doesn't have a change. I know that Sun
support GTK themes in the last JDK, but only an emulation of image
themes not native ones. And that's only because Sun
want to use Gnome 2.x for their workstations.

_This_ is really crap.

My 2 cents, Stephan.
