Event-driven execution

• Events are things that happen to a graphical
  application

• Button Presses Text Entries
• Key Presses, Key Releases, Key Events

• Each object receiving an event notifies its
  Listener
• The Listener then handles the event
  appropriately

// Here's how keyboard events are handled...
public void keyPressed(KeyEvent evt)
switch(evt.getKeyChar()) case ' '
message "You pressed a space..."
currentColor Color.white break
