Hi Omar
Sorry for delay from out side.
I'm a responsible engineer for GTK L&F.
No problem. I am just glad I am getting a response from someone who
knows this stuff.

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.
So the _correct_ behaviour is that setBackground()/setForeground() are
ignored completely? So if a component actually responds to
setBackground() or setForeground(), it's a bug?
2) The behaviour varies across jdk6 and openjdk6. For example, the
closed-source jdk6 respects
JTextPane.setBackground(UIManager.getColor("Panel.background")) but
openjdk6 ignores it. In situations like this, what is the correct
behaviour? Should I attempt to patch openjdk6 to behave more like
closed source jdk6?
It may happen because the codebases slightly different. I haven't
applied all fixes to openjdk6 which I have to jdk6.
Hope that helps.
I am still a little confused. If closed source jdk allows setting the
background, and openjdk doesn't, doesn't that mean openjdk is correct
and the fixes should be applied to the closed source jdk? Basically, I
am asking what the ideal behaviour should be. Should
setBackground()/setForeground() have any effect when using the gtk look
and feel?
Cheers,
Omair
