<Swing Dev> Request for review 7155887: ComboBox does not paint focus correctly on GTK L&F

[Jonathan Lu]

Hi Swing-dev,

ComboBox on linux GTK L&F does not works as gtk native applications, 
when get focused, the apperance of Java ComboBox remains unchanged but 
native GTK ComboBox control will have a outline to indicate it has got 
focused.

The problem seems similar to bug
6947671 ( http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6947671),
except that I did not reproduced the problem on Nimbus L&F, so another bug
7155887 (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7155887)
was created for this issue,

And here's the proposed patch to fix this problem,

Could anybody please help to take a look?

Cheers!
