QWSKeyboardHandler Class Reference

Detailed Description

The keyboard handler (driver) 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.

See also Qt/Embedded.
