Makes sense to me.  I don't really care which class contains these
methods, and I agree that fewer classes is better.  I didn't even
actually mean imply that we necessarily need to have a specialized class
(although, it probably came through that way).

But given the current status of GtkMessageDialog and since we are API
frozen there, maybe it's easier to use a different class.

Real World Applications have always been writing their own error dialog
functions...  Probably we could just look into what they have been using
so far?

You can't really expect people to be consistent with the HIG if having
things consistent with the HIG requires an unreasonable amount of coding
as it does now.  They should have to read the HIG for things that can't
be automated by the toolkit -- but everything else should be consistent
"by default".  When there are too many variables involved, there is too
high a chance for the programmer to do it wrong (or to not do it at

Besides, the basic question is: how likely is something like this to get
into 2.2?
