* Document that QtConcurrent::run doesn't support overloaded functionsSona Kurazyan2020-12-241-0/+18
| | | | | | | | | | | | | After improving QtConcurrent::run() to use parameter packs for the arguments (see c977e74afd18afff8729070f631e6b7a3f2887f5), calling overloaded functions is ambiguous. Updated the porting guide and the documentation to mention this and describe possible workarounds.

* QtConcurrent: Handle running with promise inside QTaskBuilderJarek Kobus2020-10-281-0/+9
| | | | | | | | | | | Please note, that in case of run with promise it doesn't make sense to provide the overload taking the FutureResult, as if we are going to ignore the returned QFuture object, we can't communicate with the passed QPromise.

* QtConcurrent::run: accept more then five function's argumentsVitaly Fanaskov2020-03-111-3/+33
| | | | | | | | | | | | | | [ChangeLog][Potentially Source-Incompatible Changes] QtConcurrent::run has the following signatures: run(Function &&f, Args &&...args) and run(QThreadPool *pool, Function &&f, Args &&...args). If f is a member pointer, the first argument of args should be an object for which that member is defined (or a reference, or a pointer to it). See the documentation for more details.

| | | | | | | | | | | | | | The documentation claims that function objects just work with map-reduce. They work for the map function, but not for the reduce function. Making them work for the reduce function was deemed too complex for questionable benefit, so this patch explains the situation and provides a work-around.
