Detailed Description

The QVariantAnimation class provides an abstract base class for animations.

Since: 4.6

This class is part of The Animation Framework. It serves as a base class for property and item animations, with functions for shared functionality.

QVariantAnimation cannot be used directly as it is an abstract class; it has a pure virtual method called updateCurrentValue(). The class performs interpolation over QVariant, but leaves using the interpolated values to its subclasses. Currently, Qt provides QPropertyAnimation, which animates Qt Qt's Property System{properties}. See the QPropertyAnimation class description if you wish to animate such properties.

You can then set start and end values for the property by calling setStartValue() and setEndValue(), and finally call start() to start the animation. QVariantAnimation will interpolate the property of the target object and emit valueChanged(). To react to a change in the current value you have to reimplement the updateCurrentValue() virtual function.

It is also possible to set values at specified steps situated between the start and end value. The interpolation will then touch these points at the specified steps. Note that the start and end values are defined as the key values at 0.0 and 1.0.

There are two ways to affect how QVariantAnimation interpolates the values. You can set an easing curve by calling setEasingCurve(), and configure the duration by calling setDuration(). You can change how the QVariants are interpolated by creating a subclass of QVariantAnimation, and reimplementing the virtual interpolated() function.

Subclassing QVariantAnimation can be an alternative if you have QVariant that you do not wish to declare as Qt properties. Note, however, that you in most cases will be better off declaring your QVariant as a property.

Not all QVariant types are supported. Below is a list of currently supported QVariant types:

If you need to interpolate other variant types, including custom types, you have to implement interpolation for these yourself. To do this, you can register an interpolator function for a given type. This function takes 3 parameters: the start value, the end value and the current progress.

Example:

QVariant myColorInterpolator(const QColor &start, const QColor &end, qreal progress)
{
    ...
    return QColor(...);
}
...
qRegisterAnimationInterpolator<QColor>(myColorInterpolator);

Another option is to reimplement interpolated(), which returns interpolation values for the value being interpolated.

Warning: This function is not part of the public interface. We need some snippets around here.

◆ interpolated()

protectedvirtual

This virtual function returns the linear interpolation between variants from and to, at progress, usually a value between 0 and 1.

You can reimplement this function in a subclass of QVariantAnimation to provide your own interpolation algorithm.

Note that in order for the interpolation to work with a QEasingCurve that return a value smaller than 0 or larger than 1 (such as QEasingCurve::InBack) you should make sure that it can extrapolate. If the semantic of the datatype does not allow extrapolation this function should handle that gracefully.

You should call the QVariantAnimation implementation of this function if you want your class to handle the types already supported by Qt (see class QVariantAnimation description for a list of supported types).

Properties

◆ currentValue

QVariant QVariantAnimation::currentValue

private

the current value of the animation.

This property describes the current value; an interpolated value between the start value and the end value, using the current time for progress. The value itself is obtained from interpolated(), which is called repeatedly as the animation is running.

QVariantAnimation calls the virtual updateCurrentValue() function when the current value changes. This is particularly useful for subclasses that need to track updates. For example, QPropertyAnimation uses this function to animate Qt Qt's Property System{properties}.

See also: startValue, endValue

Definition at line 65 of file qvariantanimation.h.

◆ duration

int QVariantAnimation::duration

private

the duration of the animation

This property describes the duration in milliseconds of the animation. The default duration is 250 milliseconds.

See also: QAbstractAnimation::duration()

Definition at line 66 of file qvariantanimation.h.

◆ easingCurve

QEasingCurve QVariantAnimation::easingCurve

private

the easing curve of the animation

This property defines the easing curve of the animation. By default, a linear easing curve is used, resulting in linear interpolation. Other curves are provided, for instance, QEasingCurve::InCirc, which provides a circular entry curve. Another example is QEasingCurve::InOutElastic, which provides an elastic effect on the values of the interpolated variant.

QVariantAnimation will use the QEasingCurve::valueForProgress() to transform the "normalized progress" (currentTime / totalDuration) of the animation into the effective progress actually used by the animation. It is this effective progress that will be the progress when interpolated() is called. Also, the steps in the keyValues are referring to this effective progress.

The easing curve is used with the interpolator, the interpolated() virtual function, the animation's duration, and iterationCount, to control how the current value changes as the animation progresses.

Definition at line 67 of file qvariantanimation.h.

◆ endValue

QVariant QVariantAnimation::endValue

private

the end value of the animation

This property describes the end value of the animation.

See also: startValue

Definition at line 64 of file qvariantanimation.h.

Referenced by QStateMachinePrivate::applyProperties().

◆ startValue

QVariant QVariantAnimation::startValue

private

the optional start value of the animation

This property describes the optional start value of the animation. If omitted, or if a null QVariant is assigned as the start value, the animation will use the current position of the end when the animation is started.
