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.
