Killing all threads when closing program

michalt38

Is there a way to kill all of the living threads when closing a program?

6thC

A signal that the application is shutting down, DTOR's, ThreadPools, WorkerThreads...

Without knowing your setup and even if I did know... I'm just going to say err yes?

Was there a specific case you were thinking / up against?

hi, closing a program implicates the termination of all threads. Am I right in assuming, you want to stop all threads when the UI is closed?

You can do a Signal/Slot connect when you create the thread to a complish that:

QObject::connect(qApp, &QCoreApplication::aboutToQuit, myThread, &QThread::quit);

or if your QThread is a class member you can handle that in the destructor:

myClass::~myClass(){
    myThread->quit();
    myThread->wait();
}
