Howto convert QOperatingSystemVersion::current() to string ?

[pingal]

I need a runtime OS name and version. So i used

qDebug() << QOperatingSystemVersion::current();

Which returns

QOperatingSystemVersion("Windows", 10.0.19043)

I need this object to be converted to std::string Or QString like below

Windows-10.0.19043

So just use the documentation at https://doc.qt.io/qt-5/qoperatingsystemversion.html to pick out the members you wish to print --- it's just a normal class/struct --- using say QString::arg(...) for your desired format.

Sorry, I didn't get you.

I don't know what else to say. Look at the documentation, pick the members you want to include in your string like name() or majorVersion(), and use say QString::arg() to format them into the desired string. There is nothing especially "Qt" in accessing QOperatingSystemVersion() members, it's just like any other class.
