delete/close qtconcurrent thread pool

[s002wjh]

how would i close/delete the thread pool after finish running

QFuture<void> future = QtConcurrent::run(...);

for example one of my sub window GUI are running in qthread pool, but once i close that window, how do i destroy that qthread pool. some kind signal slot ?

is there anyway to assign an id to thread pool?

Hi,

Do you mean cancel current request and delete the pool ?

By the way, why are you running GUI elements in your loop ?

Thread pools are designed to last a long time; they are not designed to be closed/deleted.

You don't need to do anything after you finish with QtConcurrent::run().

for example one of my sub window GUI are running in qthread pool

Qt does not allow GUIs to be run in a secondary thread. All GUI classes must be accessed from the GUI thread, which is the thread which created QGuiApplication/QApplication.

Probably an unfortunate turn of phrase... ;-)
