[Qt-interest] QtConcurrent::run() and updating progress bar

[Marius Roets]

Hi everybody,

I'm using QtConcurrent::run to call a method from MyClass like :

MyClass m;
QFutureWatcher *futureWatcher = new QFutureWatcher<void>;
connect(futureWatcher, SIGNAL(finished()), this, SLOT(queriesFinished()));
connect(&m, SIGNAL(runningQuery(const QString&)), this,
SLOT(runningQuery(const QString&)));
futureWatcher->setFuture(QtConcurrent::run(m, &MyClass::executeQueries));

MyClass is derived from QObject and emits the "runningQuery(const QString&)"
signal, saying which query it is currently processing. The main thread does
not seem to catch this signal though. I'm sure I'm missing something
obvious, so any suggestions would be very helpful.

Thanks
Marius
