Overview

This is a part 1 of the QSystemDeviceInfo API which is a part of the System Information API from Qt Mobility project.

What is covered in QSystemDeviceInfo API Part 1

  • It is a part of the System Information API.
  • This article covers information about
    • IMEI of the device
    • IMSI information
    • Manufacturer information
    • Model information
    • Product information
    • Battery level
    • Battery status
    • Current profile
    • SIM card status
    • Device status


Capabilities required


UI design (.ui file)

QSystemDeviceInfo UI.png


Project configuration file (.Pro file)

  • Add the Qt Mobility project configuration option in the .Pro file as shown below
CONFIG += mobility
MOBILITY += systeminfo


  • Add required capability in .pro file as shown below:
symbian:TARGET.CAPABILITY = ReadDeviceData

Implementing QSystemDeviceInfo API

  • QSystemDeviceInfo API is a part of the QtMobility namespace. So declare the QtMobility namespace as shown below:
using namespace QtMobility;

Header file

#ifndef SYSTEMDEVICEINFO_H
#define SYSTEMDEVICEINFO_H
 
#include <QtGui/QWidget>
#include "ui_SystemDeviceInfo.h"
#include <qsysteminfo.h>
 
using namespace QtMobility;
class SystemDeviceInfo : public QWidget
{
Q_OBJECT
 
public:
SystemDeviceInfo(QWidget *parent = 0);
~SystemDeviceInfo();
 
public slots:
void listDeviceInformation();
void resetAllFields();
private:
Ui::SystemDeviceInfo ui;
QSystemDeviceInfo* deviceInfo;
};
 
#endif // SYSTEMDEVICEINFO_H


Source file

#include "SystemDeviceInfo.h"
 
SystemDeviceInfo::SystemDeviceInfo(QWidget *parent)
: QWidget(parent), deviceInfo(NULL)
{
ui.setupUi(this);
deviceInfo = new QSystemDeviceInfo;
QObject::connect(ui.listDeviceInfoButton,
SIGNAL(clicked()),
this,
SLOT(listDeviceInformation()));
QObject::connect(ui.resetButton,
SIGNAL(clicked()),
this,
SLOT(resetAllFields()));
}
 
SystemDeviceInfo::~SystemDeviceInfo()
{
delete deviceInfo;
}
 
void SystemDeviceInfo::listDeviceInformation()
{
if(deviceInfo)
{
ui.imeiLabel->setText(deviceInfo->imei());
ui.imsiLabel->setText(deviceInfo->imsi());
ui.manufacturerLabel->setText(deviceInfo->manufacturer());
ui.modelLabel->setText(deviceInfo->model());
ui.productLabel->setText(deviceInfo->productName());
ui.batteryLabel->setText(QString::number(deviceInfo->batteryLevel()));
ui.batteryStatusLabel->setText(QString::number(
(QSystemDeviceInfo::BatteryStatus)deviceInfo->batteryStatus()));
ui.profileLabel->setText(QString::number(
(QSystemDeviceInfo::Profile)deviceInfo->currentProfile()));
ui.simLabel->setText(QString::number(
(QSystemDeviceInfo::SimStatus)deviceInfo->simStatus()));
ui.deviceLabel->setText(QString::number((int)deviceInfo->isDeviceLocked()));
}
}
 
void SystemDeviceInfo::resetAllFields()
{
if(deviceInfo)
{
ui.imeiLabel->clear();
ui.imsiLabel->clear();
ui.manufacturerLabel->clear();
ui.modelLabel->clear();
ui.productLabel->clear();
ui.batteryLabel->clear();
ui.batteryStatusLabel->clear();
ui.profileLabel->clear();
ui.simLabel->clear();
ui.deviceLabel->clear();
}
}
