Overview

Switching application UI orientation between landscape and portrait

Description

By default, applications are started in the current orientation of the device screen.
In order to force an application to be started in landscape mode or portrait mode, a corresponding flag needs to be passed to the BaseConstructL() function in CAknAppUi::ConstructL():
    void CMyAppUi::ConstructL()
        {
        BaseConstructL( EAknEnableSkin | EAppOrientationLandscape );    // start in landscape mode
        ...
        }
To change the orientation while the application is running, call
    void CAknAppUiBase::SetOrientationL( TAppUiOrientation aOrientation );
with either EAppUiOrientationLandscape or EAppUiOrientationPortrait as a parameter. Note that these are not the same enumeration values as those passed to BaseConstructL().
