Hi, first of all, I'd use either QProcess::setProcessChannelMode with QProcess::SeparateChannels or QProcess::MergedChannels depending on whether you want to read stdout or stderr separately or combined. Then use the QProcess::readyReadStandardOutput and/or QProcess::readyReadStandardError depending on your choice of separate or merged output channels.

If you stick with QProcess::ForwardedChannels, then you must read stdout and stderr of your main process, etc.

Good luck.
