Hey guys,

I know jordi is working on ComboBox at the moment, so I didn't know if I
could commit this change. It makes the combo button render properly when
pushed (like in windows).

In actuality the same kind of painting fixes that were applied to the
button classes need to be applied here.

So am I right to apply ?

Regards,

JBA.
