Detailed Description

The QWSKeyboardHandler class implements the keyboard driver/handler for Qt/Embedded.

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.

Member Function Documentation

QWSKeyboardHandler::QWSKeyboardHandler ()

Constructs a keyboard handler. The handler may be passed to the system for later destruction with QWSServer::setKeyboardHandler(), although even without doing this, the handler can function, calling processKeyEvent() to emit events.

QWSKeyboardHandler::~QWSKeyboardHandler () [virtual]

Destroys a keyboard handler. Note that if you have called QWSServer::setKeyboardHandler(), you may not delete the handler.

void QWSKeyboardHandler::processKeyEvent ( intunicode, intkeycode, intmodifiers, boolisPress, boolautoRepeat ) [virtual protected]

Subclasses call this function to send a key event. The server may additionally filter the event before sending it on to applications.

• unicode is the Unicode value for the key, or 0xFFFF is none is appropriate.
• keycode is the Qt keycode for the key (see Qt::Key). for the list of codes).
• modifiers is the set of modifier keys (see Qt::Modifier).
• isPress says whether this is a press or a release.
• autoRepeat says whether this event was generated by an auto-repeat mechanism, or an actual key press.
