+    \class QRunnable
+    \since 4.4
+    \brief The QRunnable class is the base class for all runnable objects.
+
+    \ingroup thread
+
+    The QRunnable class is an interface for representing a task or
+    piece of code that needs to be executed, represented by your
+    reimplementation of the run() function.
+
+    You can use QThreadPool to execute your code in a separate
+    thread. QThreadPool deletes the QRunnable automatically if
+    autoDelete() returns 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 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.
