QtConcurrent::QTaskBuilder<Task, Args...> &QTaskBuilder::onThreadPool(QThreadPool &newThreadPool)
设置任务将被调用的线程池newThreadPool 。
QFuture<QtConcurrent::InvokeResultType> QTaskBuilder::spawn()
在单独的线程中运行该任务，并立即返回一个 Future 对象。这是一个非阻塞调用。该任务可能不会立即开始。
void QTaskBuilder::spawn(QtConcurrent::FutureResult)
在单独的线程中运行该任务。这是一个非阻塞调用。该任务可能不会立即开始。
template <typename... ExtraArgs> QtConcurrent::QTaskBuilder<Task, ExtraArgs...> QTaskBuilder::withArguments(ExtraArgs &&... args)
设置任务调用时使用的参数args 。如果出现以下情况，代码格式不正确（会导致编译错误）：
- 该函数被调用超过一次。
- 参数个数为零。
QtConcurrent::QTaskBuilder<Task, Args...> &QTaskBuilder::withPriority(int newPriority)
设置任务被调用时的优先级newPriority 。
