Overview

This code example shows how to get system information programmatically in Qt using QSysInfo.

The QSysInfo class provides information about the system. The QSysInfo has two static method, s60Version() and symbianVersion(), which gives information about system. Then method s60Version() returns the version of the S60 SDK system on which the application is run. The method symbianVersion() returns the version of the Symbian operating system on which the application is run.

This snippet can be self-signed.

Preconditions

  • Download and install the Qt SDK

void SystemInfo::GetSystemInfo()
{
//Get S60 version and display it on label
switch (QSysInfo::s60Version ())

ui.label->setText("S60 version: S60 3.1");
}

{
ui.label->setText("S60 version: S60 3.2");

{
ui.label->setText("S60 version: S60 5.0");
}

case QSysInfo::SV_S60_Unknown:
{
ui.label->setText("S60 version: S60 Unknown");
}
break;
default:
break;
}
 
//Get OS version and display it on label
switch (QSysInfo::symbianVersion ())
{
case QSysInfo::QSysInfo::SV_9_2:
{
ui.label_2->setText("Symbian OS version: 9.2");
}
