Threading Classes

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

QtConcurrent

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

Concurrent Filter and Filter-Reduce

Concurrent Map and Map-Reduce

Concurrent Run

QAtomicInt

The QAtomicInt class provides platform-independent atomic operations on integers.

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.

QReadLocker

The QReadLocker class is a convenience class that simplifies locking and unlocking read-write locks for read access.

QReadWriteLock

The QReadWriteLock class provides read-write locking.

QWriteLocker

The QWriteLocker class is a convenience class that simplifies locking and unlocking read-write locks for write access.

QRunnable

The QRunnable class is the base class for all runnable objects.

QSemaphore

The QSemaphore class provides a general counting semaphore.

QThread

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

QThreadPool

The QThreadPool class manages a collection of QThreads.

QThreadStorage

The QThreadStorage class provides per-thread data storage.

QWaitCondition

The QWaitCondition class provides a condition variable for synchronizing threads.
