QProcess Real-time acquisition of output

zhiyuan_song

I want to call external programs through QProcess in QT and get the output in real time。
The core code is as follows：
ota = new QProcess(this);
connect(ota, &QProcess::readyReadStandardOutput, this, &Process::result);
ota->start("./Process.exe");
slots:
void Process::result()
{
qDebug() << "start";
qDebug() << ota->readAllStandardOutput();
}
The content in Process is as follows：
printf("aaa");

printf("bbb\n");

printf("ccc");

fflush(stdout);

My expected output is:
start
aaabbb
start
ccc
But my actual output is:
start
"aaabbb\r\nccc"
Why is that?
How can I get the output of the process in real time?
Thank you！

What do you mean by 'real-time'? The output is exactly what you print out.
