In this quick post we’ll take a look at Qt’s elegant and simple QFuture, QtConcurrentRun, and QFutureWatcher interfaces. Using these classes allows us to consume a QThreadPool thread for a specific function.
This is handy for many operations, and while simplistic in that we’re not synchronizing data, still has many uses, from processing large blocks of images to streaming chunks of data.
In this post we’ll check out some sample code for implementing QFuture.
