  \brief Keyboard driver/handler for Qt/Embedded

  The keyboard driver/handler handles events from system devices and
  generates key events.

  A QWSKeyboardHandler will usually open some system device in its
  constructor, create a QSocketNotifier on that opened device and when
  it receives data, it will call processKeyEvent() to send the event
  to Qt/Embedded for relaying to clients.

  <li>\a keycode is the Qt keycode for the key (see Qt::Key).
