Hi,

I'm trying to have some kind of highlight feature on the no-toolkit menu
bar.  As this feature is already present in tool/tab bar, I'd like to
mimic those.

While trying this, I think that I found that some "bar" functions could
be factorized (up to a certain point I guess).  Here is a patch that
shows my direction.

Do you think that this approach could make it into master or would it be
frown upon?  And if so, what would be a better way?

Best regards,
