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 PySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation([parent=None])#

Parameters:: parent – PySide6.QtCore.QObject

Constructs an QKeyframeAnimation with parent.

Note

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

property PᅟySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.easing: PySide6.QtCore.QEasingCurve#

Holds the easing curve of the interpolator between keyframes.

Access functions:

easing ()
setEasing (easing)
Signal easingChanged (easing)

property PᅟySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.endMode: RepeatMode#

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

Access functions:

endMode ()
setEndMode (mode)
Signal endModeChanged (endMode)

property PᅟySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.framePositions: 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:

framePositions ()
setFramePositions (positions)
Signal framePositionsChanged (positions)

property PᅟySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.startMode: RepeatMode#

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

Access functions:

startMode ()
setStartMode (mode)
Signal startModeChanged (startMode)

property PᅟySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.target: PySide6.Qt3DCore.Qt3DCore.QTransform#

Holds the target QTransform the animation is applied to.

Access functions:

target ()
setTarget (target)
Signal targetChanged (target)

property PᅟySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.targetName: 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:

targetName ()
setTargetName (name)
Signal targetNameChanged (name)

PySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.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.

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.

PySide6.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation.addKeyframe(keyframe)#

Parameters:: keyframe – PySide6.Qt3DCore.Qt3DCore.QTransform

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