47 \class QEasingCurve -

48 \inmodule QtCore -

49 \since 4.6 -

50 \ingroup animation -

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

52 -

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

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

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

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

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

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

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

60 -

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

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

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

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

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

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

67 -

68 For example, -

69 \code -

70 QEasingCurve easing(QEasingCurve::InOutQuad); -

71 -

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

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

74 << easing.valueForProgress(t); -

75 \endcode -

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

77 -

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

79 progress of the interpolation between startValue and endValue: -

80 \code -

81 QPropertyAnimation animation; -

82 animation.setStartValue(0); -

83 animation.setEndValue(1000); -

84 animation.setDuration(1000); -

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

86 \endcode -

87 -

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

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

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

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

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

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

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

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

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

97 -

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

99 types and lets you change the curve settings. -
