## Member Type Documentation

### enum QTimeLine::CurveShape

This enum is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

use QEasingCurve instead

This enum describes the shape of QTimeLine's value curve. The default shape is EaseInOutCurve. The curve defines the relation between the value and the timeline.

Constant | Value | Description
--- | --- | ---
`QTimeLine::EaseInCurve` | `0` | Obsolete equivalent of QEasingCurve::InCurve
`QTimeLine::EaseOutCurve` | `1` | Obsolete equivalent of QEasingCurve::OutCurve
`QTimeLine::EaseInOutCurve` | `2` | Obsolete equivalent of QEasingCurve::InOutSine
`QTimeLine::LinearCurve` | `3` | Obsolete equivalent of QEasingCurve::Linear
`QTimeLine::SineCurve` | `4` | Obsolete equivalent of QEasingCurve::SineCurve
`QTimeLine::CosineCurve` | `5` | Obsolete equivalent of QEasingCurve::CosineCurve

## Property Documentation

### curveShape : CurveShape

This property is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This property holds the shape of the timeline curve.

The curve shape describes the relation between the time and value for the base implementation of valueForTime().

This property is an indirect way to update the easingCurve property; if you set both, the one set more recently overrides the other. (If valueForTime() is reimplemented it will override both.)

By default, this property is set to EaseInOutCurve.

Access `easingCurve` instead.

Access functions:

CurveShape | curveShape() const
void | setCurveShape(CurveShape shape)

See also valueForTime() and easingCurve.
