Description
Documentation somewhat incorrectly states that tasks started by run() cannot be cancelled:
Be aware that not all asynchronous computations can be canceled. For example, the future returned by QtConcurrent::run() cannot be canceled; but the future returned by QtConcurrent::mappedReduced() can.
https://doc.qt.io/qt-5/qfuture.html#cancel
Also it says similar in here:
Note that the QFuture returned by QtConcurrent::run() does not support canceling, pausing, or progress reporting. The QFuture returned can only be used to query for the running/finished status and the return value of the function.
https://doc.qt.io/qt-5/qtconcurrent.html#run
But these tasks can be canceled if the task in question has not been started yet. ie. it could still be waiting in the queue.
