Hi,
my Problem is the other way round in comparisson to the most other users having kind of the same problem

My QFutureWacher tells me, that my Future is ready, when i am not even starting the Future... How can that be?

Qt Code: 
  1. ResourceCreator::ResourceCreator(boost::shared_ptr<Resource> _Resource, boost::function<void (ipf_viewer::RESOURCE_CREATION_STATUS)> _FuncPointer) :
  2. 		m_CreationStatus(SCHEDULED),
  3. 		m_Resource(_Resource)
  4. 	{
  5. 		m_Listener.push_back(_FuncPointer);		
  6. 		QObject::connect(&m_FutureWatcher, SIGNAL(finished()), &m_SignalMapper, SLOT(map()));
  7. 		m_SignalMapper.setMapping(&m_FutureWatcher, this);
  8. 		QObject::connect(&m_SignalMapper, SIGNAL(mapped(QObject*)), ResourceManager::getInstance(), SLOT(handleFinished(QObject*)));
  9.  
  10. 		//m_FutureResource = QtConcurrent::run(*m_Resource, &Resource::_create, this);
  11. 		m_FutureWatcher.setFuture(m_FutureResource);		
  12. 	};

So my FutureWatcher tells me, that he is ready, but i dont use run() at all! Why does it happen?
Very Interesting: I just have that problem of finished() executed and my own "handleFinished()" Slot when i am copying a boost::shared_ptr<ResourceCreator> like there:

Qt Code: 
  1. boost::shared_ptr<ResourceCreator> RC(new ResourceCreator(theResource, _FuncPointerRes));
  2. ResourceManagerData<T>::m_ScheduledCreators[_Filename] = RC;

Here is my ResourceCreator class:

Qt Code: 
  1. enum RESOURCE_CREATION_STATUS { SCHEDULED, FINISHED, CANCELLED };
  2. 	class ResourceCreator : public QObject		
  3. 	{
  4. 		Q_OBJECT
  5. 	public:
  6. 		ResourceCreator(boost::shared_ptr<Resource>, boost::function<void (ipf_viewer::RESOURCE_CREATION_STATUS)>);
  7. 		~ResourceCreator();
  8. 		void run();
  9.  
  10. 		boost::shared_ptr<Resource>				m_Resource;
  11. 		QFuture< boost::shared_ptr<Resource> >	m_FutureResource;
  12. 		QFutureWatcher< void >					m_FutureWatcher;
  13. 		QSignalMapper							m_SignalMapper;
  14. 		RESOURCE_CREATION_STATUS				m_CreationStatus;
  15. 		std::vector< boost::function<void (ipf_viewer::RESOURCE_CREATION_STATUS)> > m_Listener;
  16.  
  17. 	private:
  18. 		ResourceCreator(const ResourceCreator&);
  19. 	};

btw: It works, when i use the run() method! But it fails, through calling finished() immediately, when i dont use run()!
