QProcess::waitForReadyRead for stderr?

Question

Does QProcess::waitForReadyRead return when there is data in the process's stderr, or does it wait only on stdout? How can I wait for data on stderr without using signals and slots?

Answer 1

QProcess::setReadChannel()

Will control whether your monitoring stderr or stdout, so if you call:

myProcess->setReadChannel( QProcess::StandardError );

then waitForReadyRead will only act on stderr.
