49 \class QBasicTimer
50 \brief The QBasicTimer class provides timer events for objects.
51
52 \ingroup events
53
54 This is a fast, lightweight, and low-level class used by Qt
55 internally. We recommend using the higher-level QTimer class
56 rather than this class if you want to use timers in your
57 applications. Note that this timer is a repeating timer that
58 will send subsequent timer events unless the stop() function is called.
59
60 To use this class, create a QBasicTimer, and call its start()
61 function with a timeout interval and with a pointer to a QObject
62 subclass. When the timer times out it will send a timer event to
63 the QObject subclass. The timer can be stopped at any time using
64 stop(). isActive() returns true for a timer that is running;
65 i.e. it has been started, has not reached the timeout time, and
66 has not been stopped. The timer's ID can be retrieved using
67 timerId().
