\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. | |
