[Qt-interest] emit signal from spawned thread

[Jason H]

Your QRunnable::run() would need some way to identify its signal target, and then it could connect() in the run.

I would try inheriting from QRunnable and have a setSignalTarget(QObject*) wherein it could in run() {
connect(this, mysignal, target, slot)
}

It's the same trick used in making TCP servers multithreaded, where you set the socketDescriptor (an int)  then in the run, you pick up that descriptor and run with it, pun partially intented.

Sure. But du you see a way to connect to a signal emitted from a
function passed to QtConcurrent::run?
