Then perhaps the question should be why doesn't it make the "body" of a
static-text-dialog-item or editable-text-dialog-item colored?
Which leads into the next question. Presumably I could put a before method
on view-draw-contents for static-text-dialog-item to paint a red rectangle
and set the pen-mode and it might actaully work. *BUT*, a future (or
present; I haven't checked yet.) release may use the before method for
something. The alternative is to make a new subclass and use that, but
that is aesthetically unpleasing (to me) because I really think that the
standard static-text-dialog-item *should* use the body.
Would the makers of MACL care to comment on the pros/cons of altering the
behavior of system defined classes versus using mixin classes.
