42 \class QTimer -

43 \inmodule QtCore -

44 \brief The QTimer class provides repetitive and single-shot timers. -

45 -

46 \ingroup events -

47 -

48 -

49 The QTimer class provides a high-level programming interface for -

50 timers. To use it, create a QTimer, connect its timeout() signal -

51 to the appropriate slots, and call start(). From then on, it will -

52 emit the timeout() signal at constant intervals. -

53 -

54 Example for a one second (1000 millisecond) timer (from the -

55 \l{widgets/analogclock}{Analog Clock} example): -

56 -

57 \snippet ../widgets/widgets/analogclock/analogclock.cpp 4 -

58 \snippet ../widgets/widgets/analogclock/analogclock.cpp 5 -

59 \snippet ../widgets/widgets/analogclock/analogclock.cpp 6 -

60 -

61 From then on, the \c update() slot is called every second. -

62 -

63 You can set a timer to time out only once by calling -

64 setSingleShot(true). You can also use the static -

65 QTimer::singleShot() function to call a slot after a specified -

66 interval: -

67 -

68 \snippet timers/timers.cpp 3 -

69 -

70 In multithreaded applications, you can use QTimer in any thread -

71 that has an event loop. To start an event loop from a non-GUI -

72 thread, use QThread::exec(). Qt uses the timer's -

73 \l{QObject::thread()}{thread affinity} to determine which thread -

74 will emit the \l{QTimer::}{timeout()} signal. Because of this, you -

75 must start and stop the timer in its thread; it is not possible to -

76 start a timer from another thread. -

77 -

78 As a special case, a QTimer with a timeout of 0 will time out as -

79 soon as all the events in the window system's event queue have -

80 been processed. This can be used to do heavy work while providing -

81 a snappy user interface: -

82 -

83 \snippet timers/timers.cpp 4 -

84 \snippet timers/timers.cpp 5 -

85 \snippet timers/timers.cpp 6 -

86 -

87 From then on, \c processOneThing() will be called repeatedly. It -

88 should be written in such a way that it always returns quickly -

89 (typically after processing one data item) so that Qt can deliver -

90 events to the user interface and stop the timer as soon as it has done all -

91 its work. This is the traditional way of implementing heavy work -

92 in GUI applications, but as multithreading is nowadays becoming available on -

93 more and more platforms, we expect that zero-millisecond -

94 QTimer objects will gradually be replaced by \l{QThread}s. -

95 -

96 \section1 Accuracy and Timer Resolution -

97 -

98 The accuracy of timers depends on the underlying operating system -

99 and hardware. Most platforms support a resolution of 1 millisecond, -

100 though the accuracy of the timer will not equal this resolution -

101 in many real-world situations. -

102 -

103 The accuracy also depends on the \l{Qt::TimerType}{timer type}. For -

104 Qt::PreciseTimer, QTimer will try to keep the accurance at 1 millisecond. -

105 Precise timers will also never time out earlier than expected. -

106 -

107 For Qt::CoarseTimer and Qt::VeryCoarseTimer types, QTimer may wake up -

108 earlier than expected, within the margins for those types: 5% of the -

109 interval for Qt::CoarseTimer and 500 ms for Qt::VeryCoarseTimer. -

110 -

111 All timer types may time out later than expected if the system is busy or -

112 unable to provide the requested accuracy. In such a case of timeout -

113 overrun, Qt will emit activated() only once, even if multiple timeouts have -

114 expired, and then will resume the original interval. -

115 -

116 \section1 Alternatives to QTimer -

117 -

118 An alternative to using QTimer is to call QObject::startTimer() -

119 for your object and reimplement the QObject::timerEvent() event -

120 handler in your class (which must inherit QObject). The -

121 disadvantage is that timerEvent() does not support such -

122 high-level features as single-shot timers or signals. -

123 -

124 Another alternative is QBasicTimer. It is typically less -

125 cumbersome than using QObject::startTimer() -

126 directly. See \l{Timers} for an overview of all three approaches. -

127 -

128 Some operating systems limit the number of timers that may be -

129 used; Qt tries to work around these limitations. -

130 -
