QThread finished() emitting fails if called inside window closing

QThread finished() emitting fails if called inside window closing

I have done an application with some threads. Everything seems to work ok
if I call my stopConsumer inside a keypressedEvent. But If I call it
inside a destructor of closeEvent.. it fails.
My QThread class that has a run method like this one:
void Consumer::run()
{
forever {
// do something something
// do something something
// do something something
//-------------------------------- check for abort
abortMutex.lock();
if(abort) {
abortMutex.unlock();
qDebug() << "abort..";
break;
} abortMutex.unlock();
//-------------------------------- check for abort
}
qDebug() << "Consumer > emit finished()";
emit finished();
}
void Consumer::stopConsume() {
abortMutex.lock();
abort = true;
abortMutex.unlock();
}
and a method in the MainWindow:
void initConsumers()
{
consumer1 = new Consumer(....);
connect(consumer1, SIGNAL(finished()),
this, SLOT(deleteConsumer()));
consumer1->start();
}
void stopConsumer() {
if(consumer1!=NULL) {
qDebug() << "stopConsumer";
consumer1->stopConsume();
}
}
If I have a keypressed that calls stopConsumer.. it's ok, deleteConsumer
is reached.
If I call stopConsumer inside the MainWindow destructor or inside a
MainWindow closeEvent.. the slot deleteConsumer is never reached!
Any ideas?
