Review request for KDE Frameworks, Christoph Feck and David Faure.


Repository: kwidgetsaddons


Description
-------

If the widget gets disabled, the verification's QLineEdit is disabled as well, but its QPalette is wrong (see the screenshots).
This patch fixes the bug by setting the Active color group for the palette.
