|
| QSystemDeviceInfo | Access to device information from the system |
|---|---|
| QSystemDisplayInfo | Access to display information from the system |
| QSystemInfo | Access to various general information from the system |
| QSystemNetworkInfo | Access to network information from the system |
| QSystemScreenSaver | Access to screen saver and blanking |
| QSystemStorageInfo | Access to memory and disk information from the system |
System Information
The System Information API provides a set of APIs to discover system related information and capabilities.
Namespace
The QtMobility APIs are placed into the QtMobility namespace. This is done to facilitate the future migration of Mobility APIs into Qt. See the Quickstart guide for an example on how the namespace impacts on application development.
Overview
The System Information API returns the system information related to a number of categories.
Information Categories
Version
Contains version information for a range of supporting software on the device. For example, from the Operating System and Firmware to the version of WebKit, Qt and the Service Framework.
Features (hardware)
This lists the supported hardware on the device. Features include items such as the camera, bluetooth, GPS, FM radio etc.
Network
The state of the network connection, and also the type of network e.g. gsm, cdma, ethernet etc.
Display Information
Storage Information
The presence of various storage devices. Including: none, internal, removable, cdrom.
Device Information
- Battery Status
- Power State
- Profile (silent, vibrating, normal etc)
- Sim
- Input Method (key/buttons, keypad, qwerty, single touch screen, multitouch etc)
Screensaver
Building and compiling
This library requires Qt 4.6 to be installed.
To build the library, run qmake and make.
Linux supports a NetworkManager based backend and generic backend using QNetworkInterface only. By default the generic backend is selected. If the NetworkManager backend is required run qmake as follows:
qmake BACKEND=NetworkManager
The backend selection is expected to disappear once the API is integrated into Qt.
Examples
System Information Example
The System Information example demonstrates how an application can very easily access the system information of the device.
