You can use QThreadPool to execute your code in a separate thread. QThreadPool deletes the QRunnable automatically if autoDelete() returns \c true (the default). Use setAutoDelete() to change the auto-deletion flag. QThreadPool supports executing the same QRunnable more than once by calling QThreadPool::tryStart(this) from within the run() function. If autoDelete is enabled the QRunnable will be deleted when the last thread exits the run function. Calling QThreadPool::start() multiple times with the same QRunnable when autoDelete is enabled creates a race condition and is not recommended. \sa QThreadPool */ /*! \fn QRunnable::run() Implement this pure virtual function in your subclass. */ /*! \fn QRunnable::QRunnable() Constructs a QRunnable. Auto-deletion is enabled by default. \sa autoDelete(), setAutoDelete() */ /*! \fn QRunnable::~QRunnable() QRunnable virtual destructor. */ /*! \fn bool QRunnable::autoDelete() const Returns \c true is auto-deletion is enabled; false otherwise. If auto-deletion is enabled, QThreadPool will automatically delete this runnable after calling run(); otherwise, ownership remains with the application programmer. \sa setAutoDelete(), QThreadPool */ /*! \fn bool QRunnable::setAutoDelete(bool autoDelete) Enables auto-deletion if \a autoDelete is true; otherwise auto-deletion is disabled. If auto-deletion is enabled, QThreadPool will automatically delete this runnable after calling run(); otherwise, ownership remains with the application programmer. Note that this flag must be set before calling QThreadPool::start(). Calling this function after QThreadPool::start() results in undefined behavior. \sa autoDelete(), QThreadPool */ QT_END_NAMESPACE
