Detailed Description

TheQScreenDriverFactory class creates screen drivers in Qt for Embedded Linux.

Note that this class is only available inQt for Embedded Linux.

QScreenDriverFactory is used to detect and instantiate the available screen drivers, allowingQt for Embedded Linux to load the preferred driver into the server application at runtime. Thecreate() function returns aQScreen object representing the screen driver identified by a given key. The valid keys (i.e. the supported drivers) can be retrieved using thekeys() function.

Qt for Embedded Linux provides several built-in screen drivers. In addition, custom screen drivers can be added using Qt's plugin mechanism, i.e. by subclassing theQScreen class and creating a screen driver plugin (QScreenDriverPlugin). See thedisplay management documentation for details.
