Qt Essentials Module

The Qt Essentials module offers common applications which can be found on most devices. It is based on the Base module.

The following configure line can be used to build the Base and Essentials module only:

    ./configure -modules essentials -device xyz

Note that not specifying a device profile would result in the reference device being build.

Feature description

This module is a selection of mostly applications. It is assumed that almost every type of device will include a subset of these applications:

Feature	Details
Calculator	The Calculator allows the four basic math operations. The user interface depends on whether the target device is primarily touchscreen or keypad based.
Camera	The Camera application allows the user to take photos and videos using an integrated camera. It is supported by a plug-in based video device abstraction layer.
Clock	The Clock application displays an analog clock, can schedule user alarms and provides a stop watch.
Language	The Language application allows changing of the user interface language and the selection to be used by input methods.
Light-and-Power/ PowerManagement	The Qt Extended power management system uses a levelled approach when activating the power saving modes. Such functionality is already provided by the Base module. This module specifies the behaviour suitable for most mobile devices by providing the following actions: Dimming of display Turning display off Device and modem suspension In addition the Light-and-Power settings application allows the user to specify the time out values for the above actions.
PhotoEdit/ PhotoGallery	The photo application enables the most common picture operations such as slide shows and image categorization. Depending on the choosen user interface (Mobile or VideoIP/Deskphone) the photo application emphasizes slightly different use cases.
Systemtime	This application changes the system time and date. Additionally the date and time formats can be changed.
Notes	The Notes application can create, modify and delete user notes.
Worldtime	The Worldtime application can manage up to 5 different time zones which is used by various PIM related applications.
Initial setup	The FirstUse and Calibrate user interface simplify the initial setup process of a device. Adjustable settings are e.g. time zones, languages or touchscreen calibration data (only available on touchscreen devices).
