TimedAnimation

class TimedAnimation(**properties: Any)

Superclasses: Animation, Object

A time-based Animation.

AdwTimedAnimation implements a simple animation interpolating the given value from value_from to value_to over duration milliseconds using the curve described by easing.

If reverse is set to TRUE, AdwTimedAnimation will instead animate from value_to to value_from, and the easing curve will be inverted.

The animation can repeat a certain amount of times, or endlessly, depending on the repeat_count value. If alternate is set to TRUE, it will also change the direction every other iteration.

Constructors

class TimedAnimation

classmethod new(widget: Widget, from_: float, to: float, duration: int, target: AnimationTarget) → Animation

Creates a new AdwTimedAnimation on widget to animate target from from to to.

Parameters:

• widget – a widget to create animation on

• from

• to – a value to animate to

• duration – a duration for the animation

• target – a target value to animate

Methods

class TimedAnimation

get_alternate() → bool

Gets whether self changes direction on every iteration.

get_duration() → int

Gets the duration of self.

get_easing() → Easing

Gets the easing function self uses.

get_repeat_count() → int

Gets the number of times self will play.

get_reverse() → bool

Gets whether self plays backwards.

get_value_from() → float

Gets the value self will animate from.

get_value_to() → float

Gets the value self will animate to.

set_alternate(alternate: bool) → None

Sets whether self changes direction on every iteration.

Parameters:

alternate – whether self alternates

set_duration(duration: int) → None

Sets the duration of self.

If the animation repeats more than once, sets the duration of one iteration.

Parameters:

duration – the duration to use, in milliseconds

set_easing(easing: Easing) → None

Sets the easing function self will use.

See Easing for the description of specific easing functions.

Parameters:

easing – the easing function to use

set_repeat_count(repeat_count: int) → None

Sets the number of times self will play.

If set to 0, self will repeat endlessly.

Parameters:

repeat_count – the number of times self will play

set_reverse(reverse: bool) → None

Sets whether self plays backwards.

Parameters:

reverse – whether self plays backwards

set_value_from(value: float) → None

Sets the value self will animate from.

The animation will start at this value and end at value_to.

If reverse is TRUE, the animation will end at this value instead.

Parameters:

value – the value to animate from

set_value_to(value: float) → None

Sets the value self will animate to.

The animation will start at value_from and end at this value.

If reverse is TRUE, the animation will start at this value instead.

Parameters:

value – the value to animate to

Properties

class TimedAnimation

props.alternate: bool

Whether the animation changes direction on every iteration.

props.duration: int

Duration of the animation, in milliseconds.

Describes how much time the animation will take.

If the animation repeats more than once, describes the duration of one iteration.

props.easing: Easing

Easing function used in the animation.

Describes the curve the value is interpolated on.

See Easing for the description of specific easing functions.

props.repeat_count: int

Number of times the animation will play.

If set to 0, the animation will repeat endlessly.

props.reverse: bool

Whether the animation plays backwards.

props.value_from: float

The value to animate from.

The animation will start at this value and end at value_to.

If reverse is TRUE, the animation will end at this value instead.

props.value_to: float

The value to animate to.

The animation will start at value_from and end at this value.

If reverse is TRUE, the animation will start at this value instead.
