Detailed Description

The QAbstractSecondaryDisplay class allows developers to replace the "secondary screen" portion of the Phone UI.

The QAbstractSecondaryDisplay interface is part of is part of the server widgets framework and represents the portion of the phone UI that is shown on a smaller utility screen such as on clam shell phones.

A small tutorial on how to develop new server widgets using one of the abstract widgets as base can be found in QAbstractServerInterface class documentation.

Integration hints and requirements

• The secondary display should listen on the QPE/System qcop channel for applySecondaryBackgroundImage() messages. This message is sent when the user sets a new background image for the secondary display.
• The image information are stored in the Trolltech/qpe settings file. The HomeScreen/SecondaryHomeScreenPicture key stores the image path and HomeScreen/SecondaryHomeScreenPictureMode gives an indication how the image should be layed out (ScaleAndCrop, Center/Tile, Scale and Stretch).
• The secondary display is closely linked to the HomeScreen settings application which is used to set these values.

Note that it is not required to support all the features mentioned above.

This class is part of the Qt Extended server and cannot be used by other Qt Extended applications.
