Ok, well then the obvious question is 'does KDevelop4 use
these'? Based 
on your follow-up I am guessing 'no'?

I'm not sure I understand this. Right now I don't see any
way to 
distinguish a 'KDevelop tab button' from any other button
(not without 
pulling in KDevelop headers, anyway!), except maybe
'inherits("Button")' 
which is not very re-usable. Am I missing something? What I
want is for 
my style to draw a "button" differently depending
on if it is a normal 
button, or one of KDevelop's "tabs". A technique
that could be used by 
other apps implementing such tab bars would be nice, which
is why I 
though of overloading the style flags.

Well... yes and no. It means you would have to change the
style plug-in. 
If you are using a Qt-built-in style, then yes, technically,
you would 
have to change Qt. In my case, this would be a plug-in I
wrote, so doing 
this is trivial. Otherwise the change would just have no
effect (except 
in the very unlikely event some style is anal about what
style flags are 
set).
