Sorry for delay from out side.
I'm a responsible engineer for GTK L&F.

I have noticed a few issues in the Gtk Look and Feel and would like
to know what the correct behaviour should be. The attached program
shows a few of my concerns.
1) For each of the components, setForeground(color) and/or
setBackground(color) assignments are randomly ignored. Is this the
expected behaviour? I can understand that using the native look and
feel, the feel is exactly preserved and the programmer's preferences
are ignored. But there doesn't seem to be any consistency - some
components accept the color changes, some silently ignore it. Is
there a list showing whether setForeground() and setBackground() is
ignored for each swing component with the gtk look and feel?
Generally GTK L&F leverages theme settings for colors, indents and
fonts. And you shouldn't be able to change them using standard swing
API when GTK L&F is active. Sometimes this does work but you shouldn't
use this feature. This is the policy for GTK L&F. Actually the have
been similar requests and I tried to resolve the issue. The thing is
GTK itself doesn't allow changing colors freely for all components it
just uses the theme settings.
This is basically the policy of the Aqua Look and Feel on Mac OS X as
well. Sometimes we do pick up the foreground/background colors for some
controls where it makes sense, or the TCK requires us to, but generally,
we use our own system artwork to draw these controls.
Thanks for the insight!
Not every component (particularly non-rectangular ones) have a good
sense of what a "background" color is. Also, on Mac OS X, we are
particularly sensitive to allowing developers to create rainbow
kaleidoscope apps that clash with the rest of the Mac OS X desktop
experience, and try to make Java apps that have not necessarily tested
on our platform still look like Mac apps.
I agree, getting Java apps to blend in with the rest of the desktop
seems like the right thing to do. I just wasnt sure if that was
intentional or not in the gtk look and feel.
Cheers,
Omair
