Detailed Description

The QTransformedScreen class implements a screen driver for a transformed screen.

Warning

This function is not part of the public interface.

Note that this class is only available in Qt for Embedded Linux. Custom screen drivers can be added by subclassing the QScreenDriverPlugin class, using the QScreenDriverFactory class to dynamically load the driver into the application, but there should only be one screen object per application.

Use the QScreen::isTransformed() function to determine if a screen is transformed. The QTransformedScreen class itself provides means of rotating the screen with its setTransformation() function; the transformation() function returns the currently set rotation in terms of the Transformation enum (which describes the various available rotation settings). Alternatively, QTransformedScreen provides an implementation of the QScreen::transformOrientation() function, returning the current rotation as an integer value.
