Detailed Description
The QBasicTimer class provides timer events for objects.
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 Wiggly example uses QBasicTimer to repaint a widget at regular intervals.

Contructs a basic timer.
See also start().
QBasicTimer::~QBasicTimer ()
