Detailed Description

A QKeyframeAnimation class implements simple keyframe animation that can be used to animate QTransform. The keyframes consists of multiple timed QTransforms, which are interpolated and applied to the target QTransform. QEasingCurve is used between keyframes to control the interpolator. RepeatMode can be set for when the position set to the QKeyframeAnimation is below or above the values defined in the keyframe positions.

class RepeatMode

This enumeration specifies how position values outside keyframe values are handled.

Constant

Description

Qt3DAnimation.QKeyframeAnimation.None

The animation is not applied to the target transform.

Qt3DAnimation.QKeyframeAnimation.Constant

The edge keyframe value is used.

Qt3DAnimation.QKeyframeAnimation.Repeat

The animation is repeated.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property easingᅟ: QEasingCurve

Holds the easing curve of the interpolator between keyframes.

Access functions:
property endModeᅟ: Qt3DAnimation.QKeyframeAnimation.RepeatMode

Holds the repeat mode for the position values greater than the last frame position.

Access functions:
property framePositionsᅟ: list of float

Holds the positions of the keyframes. Each position in the list specifies the position of the corresponding keyframe with the same index. The values must be in an ascending order. Values can be positive or negative and do not have any predefined unit.

Access functions:
property startModeᅟ: Qt3DAnimation.QKeyframeAnimation.RepeatMode

Holds the repeat mode for the position values less than the first frame position.

Access functions:
property targetᅟ: QTransform

Holds the target QTransform the animation is applied to.

Access functions:
property targetNameᅟ: str

Holds the name of the target transform. This is a convenience property making it easier to match the target transform to the keyframe animation. The name is usually same as the name of the parent entity of the target transform, but does not have to be.

Access functions:
__init__([parent=None])
Parameters:

parentQObject

Constructs an QKeyframeAnimation with parent.

addKeyframe(keyframe)
Parameters:

keyframeQTransform

Adds new keyframe at the end of the animation. The QTransform can be added to the animation multiple times.
