You could use the QThread's destructor for that.
MyThread::~MyThread() {
setShouldExit(true);
wait();
}
I don't know why we don't call {quit();wait();} in the default QThread
destructor instead of calling it undefined behaviour to destroy a running
thread. Possibly because it is already too late, and the derived class has
already been destroyed.
But maybe we still could do it now.
