[edit] Overview

This is a part 2 of the QSystemNetworkInfo API which is a part of the System Information API from Qt Mobility project. The part 1 of this article can be read from Here

[edit] What is covered in QSystemNetworkInfo API Part 2

  • It is a part of the System Information API.
  • This article covers information about
  • MAC address of the specified network mode
  • Network status of the specified network mode


[edit] Capabilities required

  • ReadDeviceData


[edit] UI design (.ui file)

QSystemNetworkInfo-2 UI.PNG



[edit] 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


[edit] Implementing QSystemNetworkInfo API

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

[edit] Header file

#ifndef SYSTEMNETWORKINFO2_H
#define SYSTEMNETWORKINFO2_H
 
#include <QtGui/QWidget>
#include "ui_SystemNetworkInfo2.h"
#include <qsysteminfo.h>
 
using namespace QtMobility;
class SystemNetworkInfo2 : public QWidget
{
Q_OBJECT
 
public:
SystemNetworkInfo2(QWidget *parent = 0);
~SystemNetworkInfo2();
 
public slots:
void displayNetworkInfo(int aIndex);
void resetAllFields();
 
private:
QString getNetworkStatusString(QSystemNetworkInfo::NetworkStatus aIndex);
 
private:
Ui::SystemNetworkInfo2 ui;
QSystemNetworkInfo* networkInfo;
};
 
#endif // SYSTEMNETWORKINFO2_H


[edit] Source file

#include "SystemNetworkInfo2.h"
 
SystemNetworkInfo2::SystemNetworkInfo2(QWidget *parent)
: QWidget(parent), networkInfo(NULL)
{
ui.setupUi(this);
networkInfo = new QSystemNetworkInfo();
QObject::connect(ui.comboBox,
SIGNAL(currentIndexChanged(int)),
this,
SLOT(displayNetworkInfo(int)));
QObject::connect(ui.resetButton,
SIGNAL(clicked()),
this,
SLOT(resetAllFields()));
}
 
SystemNetworkInfo2::~SystemNetworkInfo2()
{
delete networkInfo;
networkInfo = NULL;
}
 
void SystemNetworkInfo2::displayNetworkInfo(int aIndex)
{
if(! aIndex)
{
resetAllFields();
return;
}
 
QString macAddress = networkInfo->macAddress((QSystemNetworkInfo::NetworkMode)aIndex);
if(! macAddress.length())
{
ui.macLabel->setText("Not applicable");
}
else
{
ui.macLabel->setText(macAddress);
}
ui.statusLabel->setText(getNetworkStatusString(
networkInfo->networkStatus(
(QSystemNetworkInfo::NetworkMode)aIndex)));
}
 
QString SystemNetworkInfo2::getNetworkStatusString(QSystemNetworkInfo::NetworkStatus aIndex)
{
switch(aIndex)
{
case QSystemNetworkInfo::UndefinedStatus:
{
return "Undefined";
}
case QSystemNetworkInfo::NoNetworkAvailable:
{
return "Unavailable";
}
case QSystemNetworkInfo::EmergencyOnly:
{
return "Emergency";
}
case QSystemNetworkInfo::Searching:
{
return "Searching";
}
case QSystemNetworkInfo::Busy:
{
return "Busy";
}
case QSystemNetworkInfo::Connected:
{
return "Connected";
}
case QSystemNetworkInfo::HomeNetwork:
{
return "On home n/w";
}
case QSystemNetworkInfo::Denied:
{
return "Access denied";
}
case QSystemNetworkInfo::Roaming:
{
return "On Roaming";
}
default:
{
return "Error";
}
}
}
 
void SystemNetworkInfo2::resetAllFields()
{
ui.macLabel->clear();
ui.statusLabel->clear();
ui.comboBox->setCurrentIndex(0);
}
