QScreenDriverFactory Class Reference
^{[QtGui module]}

Detailed Description

The QScreenDriverFactory class creates QScreen objects.

Note that this class is only available in Qtopia Core.

The QScreen class and its descendants manage the framebuffer and palette. QScreenDriverFactory creates a QScreen object using the create() function and a key identifying the driver.

The valid keys (i.e. the supported drivers) can be retrieved using the keys() function. The drivers are either built-in or dynamically loaded from a driver plugin (see QScreenDriverPlugin).

See also QScreen and QScreenDriverPlugin.
