Unsolved QProcess Real-time acquisition of output
-
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.
