53 \class QEasingCurve -

54 \inmodule QtCore -

55 \since 4.6 -

56 \ingroup animation -

57 \brief The QEasingCurve class provides easing curves for controlling animation. -

58 -

59 Easing curves describe a function that controls how the speed of the interpolation -

60 between 0 and 1 should be. Easing curves allow transitions from -

61 one value to another to appear more natural than a simple constant speed would allow. -

62 The QEasingCurve class is usually used in conjunction with the QVariantAnimation and -

63 QPropertyAnimation classes but can be used on its own. It is usually used to accelerate -

64 the interpolation from zero velocity (ease in) or decelerate to zero velocity (ease out). -

65 Ease in and ease out can also be combined in the same easing curve. -

66 -

67 To calculate the speed of the interpolation, the easing curve provides the function -

68 valueForProgress(), where the \a progress argument specifies the progress of the -

69 interpolation: 0 is the start value of the interpolation, 1 is the end value of the -

70 interpolation. The returned value is the effective progress of the interpolation. -

71 If the returned value is the same as the input value for all input values the easing -

72 curve is a linear curve. This is the default behaviour. -

73 -

74 For example, -

75 \code -

76 QEasingCurve easing(QEasingCurve::InOutQuad); -

77 -

78 for(qreal t = 0.0; t < 1.0; t+=0.1) -

79 qWarning() << "Effective progress" << t << " is -

80 << easing.valueForProgress(t); -

81 \endcode -

82 will print the effective progress of the interpolation between 0 and 1. -

83 -

84 When using a QPropertyAnimation, the associated easing curve will be used to control the -

85 progress of the interpolation between startValue and endValue: -

86 \code -

87 QPropertyAnimation animation; -

88 animation.setStartValue(0); -

89 animation.setEndValue(1000); -

90 animation.setDuration(1000); -

91 animation.setEasingCurve(QEasingCurve::InOutQuad); -

92 \endcode -

93 -

94 The ability to set an amplitude, overshoot, or period depends on -

95 the QEasingCurve type. Amplitude access is available to curves -

96 that behave as springs such as elastic and bounce curves. Changing -

97 the amplitude changes the height of the curve. Period access is -

98 only available to elastic curves and setting a higher period slows -

99 the rate of bounce. Only curves that have "boomerang" behaviors -

100 such as the InBack, OutBack, InOutBack, and OutInBack have -

101 overshoot settings. These curves will interpolate beyond the end -

102 points and return to the end point, acting similar to a boomerang. -

103 -

104 The \l{Easing Curves Example} contains samples of QEasingCurve -

105 types and lets you change the curve settings. -
