[edit] Overview

This is a part 2 of the QSystemInfo API which is a part of the System Information API from Qt Mobility project.


[edit] What is covered in QSystemInfo API Part 2

  • It is a part of the System Information API.
  • This article covers information about
    • Available features of the device
    • Version information of the OS
    • Current firmware information of the device


[edit] Capabilities required

  • ReadDeviceData


[edit] UI design (.ui file)

SystemFeatureInfo 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 Qt-specific configuration options in .pro file as shown below
QT += network
  • Add required capability in .pro file as shown below:
symbian:TARGET.CAPABILITY = ReadDeviceData


[edit] Implementing QSystemInfo API

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

[edit] Header file

#ifndef SYSTEMFEATUREINFO_H
#define SYSTEMFEATUREINFO_H
 
#include <QtGui/QWidget>
#include "ui_SystemFeatureInfo.h"
#include <qsysteminfo.h>
 
using namespace QtMobility;
class SystemFeatureInfo : public QWidget
{
Q_OBJECT
 
public:
SystemFeatureInfo(QWidget *parent = 0);
~SystemFeatureInfo();
 
public slots:
void checkFeatureAvailability(int aIndex);
void listFirmwareInformation();
void resetAllFields();
 
private:
Ui::SystemFeatureInfo ui;
QSystemInfo* sysInfo;
};
 
#endif // SYSTEMFEATUREINFO_H


[edit] Source file

#include "SystemFeatureInfo.h"
 
SystemFeatureInfo::SystemFeatureInfo(QWidget *parent)
: QWidget(parent), sysInfo(NULL)
{
ui.setupUi(this);
sysInfo = new QSystemInfo();
 
QObject::connect(ui.featureComboBox,
SIGNAL(currentIndexChanged(int)),
this,
SLOT(checkFeatureAvailability(int)));
QObject::connect(ui.listVersionInfoButton,
SIGNAL(clicked()),
this,
SLOT(listFirmwareInformation()));
QObject::connect(ui.resetButton,
SIGNAL(clicked()),
this,
SLOT(resetAllFields()));
}
 
SystemFeatureInfo::~SystemFeatureInfo()
{
delete sysInfo;
sysInfo = NULL;
}
 
void SystemFeatureInfo::checkFeatureAvailability(int aIndex)
{
ASSERT(aIndex >=0 && aIndex <=13);
 
if(! aIndex)
{
ui.label->clear();
return;
}
 
bool val = sysInfo->hasFeatureSupported((QSystemInfo::Feature)(aIndex-1));
if(val)
{
ui.label->setText("Available");
}
else
{
ui.label->setText("Not available");
}
}
 
void SystemFeatureInfo::listFirmwareInformation()
{
if(sysInfo)
{
QString os = sysInfo->version(QSystemInfo::Os);
ui.OSlabel->setText(sysInfo->version(QSystemInfo::Os));
ui.qtLabel->setText(sysInfo->version(QSystemInfo::QtCore));
ui.firmwareLabel->setText(sysInfo->version(QSystemInfo::Firmware));
}
}
void SystemFeatureInfo::resetAllFields()
{
ui.featureComboBox->setCurrentIndex(0);
ui.label->clear();
ui.OSlabel->clear();
ui.qtLabel->clear();
ui.firmwareLabel->clear();
}
