Threading Classes

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

QtConcurrent

High-level APIs that make it possible to write multi-threaded programs without using low-level threading primitives

QAtomicInteger

Platform-independent atomic operations on integers

Template class that provides platform-independent atomic operations on pointers

QFuture

Represents the result of an asynchronous computation

QFutureSynchronizer

Convenience class that simplifies QFuture synchronization

QFutureWatcher

Allows monitoring a QFuture using signals and slots

QMutex

Access serialization between threads

QMutexLocker

Convenience class that simplifies locking and unlocking mutexes

QReadLocker

Convenience class that simplifies locking and unlocking read-write locks for read access

QReadWriteLock

Read-write locking

QWriteLocker

Convenience class that simplifies locking and unlocking read-write locks for write access

QRunnable

The base class for all runnable objects

QSemaphore
