谢谢！
里面有这种方法，可以不：

// helloconcurrent/main.cppvoid hello(){qDebug() << "Hello from thread " << QThread::currentThread();}int main(int argc, char *argv[]){QCoreApplication app(argc, argv);QFuture<void> future = QtConcurrent::run(hello);qDebug() << "hello from GUI thread " << QThread::currentThread();future.waitForFinished();return 0;}

里面的这种方法，可以不？：


// helloconcurrent/main.cpp
void hello()
{
     qDebug() << "Hello from thread " << QThread::currentThread();
}

int main(int argc, char *argv[])
{
     QCoreApplication app(argc, argv);
     QFuture<void> future = QtConcurrent::run(hello);
     qDebug() << "hello from GUI thread " << QThread::currentThread();
     future.waitForFinished();
     return 0;
}
