Qt3DAnimation.QKeyframeAnimation ¶

概要 ¶

详细描述 ¶

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 PySide2.Qt3DAnimation.Qt3DAnimation. QKeyframeAnimation ( [ parent=None ] ) ¶

param parent

QObject

Constructs an QKeyframeAnimation with parent .

PySide2.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation. RepeatMode ¶

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

常量	描述
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.

PySide2.Qt3DAnimation.Qt3DAnimation.QKeyframeAnimation. addKeyframe ( keyframe ) ¶

参数

keyframe – QTransform

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