Rotation

Example

The Rotation settings application is an example of user based rotation.

A device integrator could also want to automatically rotate the screen depending on which way the user holds the device, if the device has motion sensors.

To rotate the screen 270 degrees clockwise, send a request to the RotationManager:

       QtopiaServiceRequest svreq("RotationManager", "setCurrentRotation(int)");
       svreq << 270;
       svreq.send();

To set the display back to the default orientation:

       QtopiaServiceRequest svreq("RotationManager", "defaultRotation()");
       svreq.send();

Applications that need to access the current and default screen orientation values may use a QValueSpaceItem defined in the RotationManager.

        QValueSpaceItem *currentRotation = new QValueSpaceItem("/UI/Rotation/Current");
        int currentRot = currentRotation->value().toUInt();

        QValueSpaceItem *defaultRotation = new QValueSpaceItem("/UI/Rotation/Default");
        int defaultRot = defaultRotation->value().toUInt();
