<h2>Detailed Description</h2>
|
|
<p>The QBasicTimer class provides timer events for objects.</p>
|
|
<p>This is a fast, lightweight, and low-level class used by Qt internally. We recommend using the higher-level <a href="qtimer.html">QTimer</a> class rather than this class if you want to use timers in your applications. Note that this timer is a repeating timer that will send subsequent timer events unless the <a href="qbasictimer.html#stop">stop</a>() function is called.</p>
|
|
<p>To use this class, create a QBasicTimer, and call its <a href="qbasictimer.html#start">start</a>() function with a timeout interval and with a pointer to a <a href="qobject.html">QObject</a> subclass. When the timer times out it will send a timer event to the <a href="qobject.html">QObject</a> subclass. The timer can be stopped at any time using <a href="qbasictimer.html#stop">stop</a>(). <a href="qbasictimer.html#isActive">isActive</a>() 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 <a href="qbasictimer.html#timerId">timerId</a>().</p>
|
|
<p>The <a href="widgets-wiggly.html">Wiggly</a> example uses QBasicTimer to repaint a widget at regular intervals.</p>
