The following comparisons can be done in Ada 95:

if target in Button then ...
if target in Component'class then ...

I don't know of a way to compare the types Button and Component in order
to determine if Button is derived from Component. That doesn't mean that
there is no way to do it, only that I don't know how to do it.
