Function Documentation▲
int QtConcurrent::run(Function, ...)▲
Equivalent to
QtConcurrent::run(QThreadPool::globalInstance(), function, ...);Runs function in a separate thread. The thread is taken from the global QThreadPool. Note that function may not run immediately; function will only be run once a thread becomes available.
T is the same type as the return value of function. Non-void return values can be accessed via the QFuture::result() function.
The QFuture returned can only be used to query for the running/finished status and the return value of the function. In particular, canceling or pausing can be issued only if the computations behind the future has not been started.
