Hi Gordon,

Done now, through the appended patch.
This all looks reasonable. What happens if the l&f class has been
explicitly set by the user through the system property, or though the
Swing APIs? It would be better if we did not override the l&f in that
case. But I'm not sure we can detect this in all cases...
One thing I'm not comfortable with is that the default L&F choice is
LAFChoiceNativeSystemForceGtk, which is exactly the same as you did.
The reason is that on the Linux system I happen to be using (openSUSE with KDE
desktop), the Gtk look&feel of Swing is not well supported: At the beginning
I get an error message in the console:
/opt/gnome/share/themes/Qt/gtk-2.0/gtkrc:5: Engine "qtengine" is unsupported, ignoring
I've seen this message before, and it depends on the window manager
used, but there's nothing (reasonable) we can do to detect this situation.
BTW, if you haven't seen it, I found this article has some useful
information on the evolution of the GTK l&f:
http://www.ffnn.nl/pages/articles/java/java-2-se-6.0-aesthetics-preview.php
In view of the bug that you found and reported
https://bugs.eclipse.org/bugs/show_bug.cgi?id=126931
I think we must even make it
LAFChoiceNativeSystemAvoidGtk
when running under JDK 1.6.
Yes, ideally, this should be the default under 1.6.
