Overview
This is a part 2 of the QSystemInfo API which is a part of the System Information API from Qt Mobility project.
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
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 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
Implementing QSystemInfo API
- QSystemInfo API is a part of the QtMobility namespace. So declare the QtMobility namespace as shown below:
using namespace QtMobility;
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
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();
}
Output
Useful functions
- bool hasFeatureSupported(QSystemInfo::Feature feature);
- QString version(QSystemInfo::Version type, const QString & parameter = QString());
Keywords
Headers
- #include <qsysteminfo.h>
Classes
- QSystemInfo
- QString
- QStringList
- QButton
- QLabel
- QComboBox
Example Application
- A working example application is available to download from here: QSystemInfo part2.zip
