Detect operating system, physical memory and other system information

[mvbhavsar]

I want to collect information that what is current OS, how physical memory (RAM) does the machine has, how much disk space etc. I tried to use QSysInfo but was not able to get what I am looking for.
Also in some document it is written that QSysInfo::WindowsVersion() function is there but this is also missing in QSysInfo. QSysInfo has very few options.

It's hard to gather such information from a single source and definitely not in a cross-platform way. On Unix you'd have to parse some files in /proc, for example.

Does is required to modify .pro file to get all options of QSysInfo::WindowsVersion()

How are you trying to access them?

it is leading to only google search page for this phrase. I want to calculate available physical memory on a machine using QT.

Congratulations, that was the idea. Now look at the results and follow the one that looks like it knows how to calculate available physical memory using C++.

Qt is a framework, not a language. If you can't see the functionality in the Qt documentation, then look for a C++ solution. It's not difficult, Wysota even created the google query for you.
