Is it possible to use Qt threading without inheriting any Qt object?

Question

The only way to enable threading demonstrated in qt documentation is through inheriting QThread and then override its run() method.

class MyThread : public QThread
 {
 public:
     void run();
 };

 void MyThread::run()
 {
     QTcpSocket socket;
     // connect QTcpSocket's signals somewhere meaningful
     ...
     socket.connectToHost(hostName, portNumber);
     exec();
 }

I wonder if there is any way to use qt thread without ever inheriting from any qt objects?

Answer 1

You can use multithreading without inheriting from QObject with QtConcurrent::run():

QFuture QtConcurrent::run ( Function function, ... )
Runs function in a separate thread. The thread is taken from the global QThreadPool. Note that the function may not run immediately; the function will only be run when a thread is available.
