Two nested squares both listen to ``tap'' gestures. The two figures
both show a touch object triggering an event, represented by a
black dot. The event is delegated through the event area tree in
the order indicated by the numbered arrow labels. Dotted arrows

An object touching the screen is essentially touching the deepest event
area in the tree that contains the triggered event. That event area should
be the first to delegate the event to its gesture detection components, and
then propagate the event up in the tree to its ancestors. A gesture
detection component can stop the propagation of the event by its
corresponding event area.

The concept of an event area is based on the assumption that the set of
originating events that form a particular gesture, can be determined based
exclusively on the location of the events. This is a reasonable assumption
