Foil 30 Events in the java.awt -- Mouse, Keyboard Interaction - I

From Java Tutorial - Spring 1997 Part 3:Graphics and the Abstract Windowing Toolkit Peking Tutorial, Web Certificate -- Spring-Summer 1997. by Nancy J. McCracken,Geoffrey C. Fox


Events ( distinguish these from Exceptions!) are the way the AWT interacts with the user at mouse or keyboard.
The AWT calls particular event handlers (analogous to exception or interrupt handlers) when user interacts with system in particular ways.
The handling is defined in packages java.awt and java.awt.peer (the machine dependent stuff) with method handleEvent() in class Component(peer)
One could add additional capability here for systems with nifty virtual reality and other user interfaces but we won't cover this here!
