An event that is triggered when a key is pressed,released or remains pressed on a keyboard input device.

A KeyEvent is an event that is triggered when a key is pressed, released or remains pressed on a keyboard input device. The event can contain:

  • info about particular key that was pressed/released
  • how long the key was pressed
  • whether any modifier keys were also pressed (such as Ctrl or Alt).
  • type of event - press, release, other (for example character was typed, regardless whether key was pressed or released)

Some platforms/keyboards may generate auto-repeat key events - same character is typed repeatedly while key remain pressed
