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
Capabilities required
- ReadDeviceData
UI design (.ui file)
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();
}
}
