I think this is the direction we should go in: build the future API around
C++11 lambdas.
This reduces the need for QFuture and especially QFutureWatcher. Thiago pointed
out the waiting case above. Instead of connecting to
QFutureWatcher::finished(), create a signal and emit when the work is done:
MyObject::asyncWork()
{
runFunction([]() {
Result result = doWork();
emit done(result); // signal on MyObject
});
}
