You can connect your own handler to the destroy signal and do whatever
things, set a flag, zap a variable, destroy something associated.

It's often friendlier to use weak refs than rely on a destroy to clean
things up, though sometimes there's unavoidable circular refs, even in
gtk itself, which have to be broken by a destroy.
