    \class QKbdDriverFactory

    \ingroup qws

    \brief The QKbdDriverFactory class creates keyboard drivers in

    Qt for Embedded Linux.

    Note that this class is only available in \l{Qt for Embedded Linux}.

    QKbdDriverFactory is used to detect and instantiate the available

    keyboard drivers, allowing \l{Qt for Embedded Linux} to load the preferred

    driver into the server application at runtime. The create()

    function returns a QWSKeyboardHandler object representing the

    keyboard driver identified by a given key. The valid keys

    (i.e. the supported drivers) can be retrieved using the keys()

    function.

    \l{Qt for Embedded Linux} provides several built-in keyboard drivers. In

    addition, custom keyboard drivers can be added using Qt's plugin

    mechanism, i.e. by subclassing the QWSKeyboardHandler class and

    creating a keyboard driver plugin (QKbdDriverPlugin). See the

    \l{Qt for Embedded Linux Character Input}{character input} documentation

    for details.
