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. \sa QWSKeyboardHandler, QKbdDriverPlugin */ /*!
