Problem here is that you need more than this to get proper UI:

 - you should only ask if there are unsaved changes, rather than 
   anytime window closes
 - the question should be more specific, like:
    Document 'Whatever' has unsaved changes. [Cancel] [Discard] [Save]
   (GNOME HIG has a specific suggestion for wording probably)

There's a bug open for this already (called something about "validation"
if you search for it). Just need someone to work on it. Would be a very
valuable feature.

My feeling is that this isn't a common enough operation. I can't think
of a single example of this in all of GNOME for example.

It may be more common in in-house apps that tend to hardcode
colors/sizes which would violate i18n/a11y guidelines for
general-purpose public apps.

There were some of these in libgnomeui, basically deprecated now. They
turned out to be somewhat too hardcoded/inflexible so often went unused.
GtkMessageDialog is the outcome of the most recent API discussion in
this area.
