+/*!
+    \class QBasicTimer
+    \brief The QBasicTimer class provides timer events for objects.
+
+    \ingroup events
+
+    This is a fast, lightweight, and low-level class used by Qt
+    internally. We recommend using the higher-level QTimer class
+    rather than this class if you want to use timers in your
+    applications.
+
+    To use this class, create a QBasicTimer, and call its start()
+    function with a timeout interval and with a pointer to a QObject
+    subclass. When the timer times out it will send a timer event to
+    the QObject subclass. The timer can be stopped at any time using
+    stop(). isActive() returns true for a timer that is running;
+    i.e. it has been started, has not reached the timeout time, and
+    has not been stopped. The timer's ID can be retrieved using
+    timerId().
+
+    The \l{widgets/wiggly}{Wiggly} example uses QBasicTimer to repaint
+    a widget at regular intervals.
+
