"Blocking" a QThread until a signal has arrived

[anda_skoa]

Maybe there is an easier way: QIODevice, the base class of QProcess has a waitForReadyRead() function that can be used to blockingly wait for the readyRead() signal emit.

Alternatively you could start the thread's event loop when you "wait" and stop it when you are done

void get_something()
{
    // wait in event loop
    exec();
}
 
void set_something()
{
    // stop event loop
    quit();
}

void get_something()
{
    // wait in event loop
    exec();
}

void set_something()
{
    // stop event loop
    quit();
}

To copy to clipboard, switch view to plain text mode 

And for completeness: the "missing" function in your original code is QThread::eventDispatcher().
