Converting low-level events to high level events
The native operating system and user interface only send
low-level events. They do not send ActionEvents, TextEvents,
ItemEvents, or AdjustmentEvents. Instead each component
which fires these events first listens for low-level events like key presses.
(Actually, the component's peer does this.)
When it sees the right low-level event or combination of low level events,
it eats those events and fires a new high level event.
