If buttons and widgets are wholly incompatible and separate then button-at should return nil when on a widget even if both buttons and widgets use the same underlying mechanism.  This is what abstractions are for.  The implementation should be hidden.

The abstraction I really want is if there is a clickable item under point, activate it in the most appropriate way, e.g. if selected with a mouse event, use it’s mouse action, etc.  Maybe an activate-at function that handles different types of objects with a priority order if there are multiple matches.
