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.
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:
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). |
The PIM module includes the following software components:
The exact list of components included in this module can be found in $QPEDIR/src/module_essentials.pri.
The test plan for the Essentials module summarizes the Quality Assurance procedures for this module. The results of these test are available here.
The following table contains all classes and services which are part of this module:
| APMBattery | QPowerSource mapping to the Linux APM interface |
|---|---|
| Alarm | The Alarm service |
| Camera | The Camera service |
| CleanupWizard | The CleanupWizard service |
| Clock | The Clock service |
| Date | The Date service |
| FirstUse | Setup wizard that is shown the first time the device is turned on |
| PhonePowerManager | Implements phone specific power management functionality in Qtopia |
| PhotoEdit | The PhotoEdit service |
| QKeyboardLock | Convenient way of blocking any keyboard input |
| QtopiaCamera | Common camera definitions |
| QtopiaVideo | Common video definitions |
| Time | The Time service |
