Threading Classes

These Qt Core classes provide threading support to applications. The Thread Support in Qt page covers how to use these classes.

• Concurrent Filter and Filter-Reduce:

• Concurrent Map and Map-Reduce:

• Concurrent Run:

• QAtomicPointer: The QAtomicPointer class is a template class that provides platform-independent atomic operations on pointers.

• QFuture: The QFuture class represents the result of an asynchronous computation.

• QFutureSynchronizer: The QFutureSynchronizer class is a convenience class that simplifies QFuture synchronization.

• QFutureWatcher: The QFutureWatcher class allows monitoring a QFuture using signals and slots.

• QMutex: The QMutex class provides access serialization between threads.

• QMutexLocker: The QMutexLocker class is a convenience class that simplifies locking and unlocking mutexes.

• QSemaphoreReleaser: The QSemaphoreReleaser class provides exception-safe deferral of a QSemaphore::release() call.

• QThread: The QThread class provides a platform-independent way to manage threads.

• QThreadStorage: The QThreadStorage class provides per-thread data storage.

• QtConcurrent: The QtConcurrent namespace provides high-level APIs that make it possible to write multi-threaded programs without using low-level threading primitives.
