read QProcess output to string

Question

I have a code that uses QProcess like this.

int main(int argc, char *argv[])
{
    int status=0;
    QProcess pingProcess;
    QString ba;
    QString exec =         


        

Answer 1

Did you try QByteArray QProcess::readAllStandardOutput() docs - here

QString can be instantiated from QByteArray:

QString output(pingProcess.readAllStandardOutput());

As others mentioned, and I join to them, you should not use execute method and replace it with:

pingProcess.start(exec, params);
pingProcess.waitForFinished(); // sets current thread to sleep and waits for pingProcess end
QString output(pingProcess.readAllStandardOutput());
