device <-pointed_objects: at=point|event, append_to=[chain] -> chain

Determines all objects that overlap with some position. This method is used internally to determine the objects to which an event should be send. The first argument describes the position. It is either a point or an event. In the latter case the position of the event is taken.

If chain is supplied, this chain is filled with the matching graphicals. This chain is chain->cleared first. If it is @default, a new chain object with the matching graphicals it returned.

The matching graphicals are the graphicals for which‘Graphical graphical->in_event_area’succeeds. The graphicals are stored in the chain, such that the top-most graphical is the head of the chain.
