How to I get cpu description and cpu name

    if (OSName == "windows")
    {
        QChar getcpu = system("wmic cpu get description");
        QString cpucorp = "convert getcpu to string";
        ui->cpuCorp->setText("view the cpucorp output");

    }

I need the program to get the name of the cpu and its "Intel / Amd" corporation, but I saw two ways to do that.

1. The first one and use the WMIC api in qt, but how do I do this?

2. How can I convert the system () command from char to string in qt? because even reading the documentation, none of the forms presented worked.

Hi,

Both can be done using QProcess.

@SGaist

Sorry for "delay", in windows until it occurred + - as I wanted, but in Linux it does not display the information I want from the right way

        ui->selectHardware->addItem("CPU");

That's because you are using pipes in your command. Either user several QProcess objects from which you connect the standard output to the following process standard input or write a script that does that.

Note that since it's a file, you can also use QFile to read from it.

@SGaist Look, I've researched here, but would you have any idea of a script to just get the name of the gpu and its linux corporation? Because I'm just meeting for windows

[SGaist]

Something like lspci -vnn | grep VGA ?
