Programs written +with Qt Concurrent automatically adjust the number of threads used according to +the number of processor cores available. This means that applications written +today will continue to scale when deployed on multi-core systems in the future. + +Qt Concurrent includes functional programming style APIs for parallel list +processing, including a MapReduce and FilterReduce implementation for +shared-memory (non-distributed) systems, and classes for managing asynchronous +computations in GUI applications: + + * :class:`QFuture<PySide6.QtCore.QFuture>` represents the result of an + asynchronous computation. + * :class:`QFutureIterator<~.QFutureIterator>` allows iterating through results + available via :class:`QFuture<PySide6.QtCore.QFuture>` . + * :class:`QFutureWatcher<PySide6.QtCore.QFutureWatcher>` allows monitoring a + :class:`QFuture<PySide6.QtCore.QFuture>` using signals-and-slots. + * :class:`QFutureSynchronizer<~.QFutureSynchronizer>` is a convenience class + that automatically synchronizes several QFutures. + * :class:`QPromise<~.QPromise>` provides a way to report progress and results + of the asynchronous computation to :class:`QFuture<PySide6.QtCore.QFuture>` . + Allows suspending or canceling the task when requested by + :class:`QFuture<PySide6.QtCore.QFuture>` . + +Using the Module +^^^^^^^^^^^^^^^^ + +To include the definitions of modules classes, use the following +directive: + +:: + + import PySide6.QtConcurrent |
