pub fn set_playback_behavior(&self, value: PlaybackBehavior)

pub fn fill_mode_property() -> &'static DirectProperty<Animation, FillMode>

Defines the FillMode property: the value fill mode.

pub fn fill_mode(&self) -> FillMode

pub fn set_fill_mode(&self, value: FillMode)

pub fn delay_property() -> &'static DirectProperty<Animation, TimeSpan>

Defines the Delay property: the initial delay time.

Defines the DelayBetweenIterations property.

pub fn delay_between_iterations(&self) -> TimeSpan

pub fn set_delay_between_iterations(&self, value: TimeSpan)

pub fn easing_property() -> &'static DirectProperty<Animation, Easing>

Defines the Easing property: the easing function to be used.

pub fn speed_ratio_property() -> &'static DirectProperty<Animation, f64>

Defines the SpeedRatio property: the speed multiple.

pub fn construct() -> Self

Creates the class data; see FerroObject::construct.

pub fn new() -> Ref<Self>

pub fn easing(&self) -> Easing

The easing function to be used for this animation.

pub fn set_easing(&self, value: impl Into<Easing>)

pub fn speed_ratio(&self) -> f64

The speed multiple for this animation.

pub fn apply( &self, control: &Animatable, clock: Option<Rc<dyn IClock>>, match_: Rc<dyn IObservable<bool>>, on_complete: Option<Rc<dyn Fn()>>, is_manually_started: bool, ) -> Rc<dyn IDisposable>

Applies the animation to control: it runs while match_ is true, on clock (or on the control’s clock, or on the global clock). on_complete runs when the animation ends by itself. is_manually_started tells an animation started by code from one started by a style. Disposing the result removes the animation.

pub fn run_async( &self, control: &Animatable, cancellation_token: CancellationToken, ) -> AnimationTask

Starts the animation on control and returns a task that completes when it has ended or cancellation_token was cancelled.

pub fn run_async_with_clock( &self, control: &Animatable, clock: Option<Rc<dyn IClock>>, cancellation_token: CancellationToken, ) -> AnimationTask

run_async on an explicit clock.

impl Animation

pub fn set_animator( setter: &Rc<dyn IAnimationSetter>, value: Rc<dyn ICustomAnimator>, )

Sets the value of the Animator attached property for a setter: the custom animator that animates the setter’s property instead of the one selected by the property’s type.

pub fn register_custom_animator<TAnimator: InterpolatingAnimator + Default>()

Registers a user-provided animator for properties of its value type. It takes precedence over the animators registered before it.

Methods from Deref<Target = FerroObject>

pub fn dispatcher(&self) -> &Arc<Dispatcher>

pub fn check_access(&self) -> bool

Returns whether the calling thread is the thread that owns this object.

pub fn verify_access(&self)

Checks that the calling thread is the thread that owns this object.

Panics

Panics when it is not.

pub fn to_ref(&self) -> Ref<FerroObject>

A strong reference to this object.

pub fn to_weak(&self) -> WeakRef<FerroObject>

A weak reference to this object.

pub fn get_type(&self) -> &'static TypeInfo

The runtime type of the object.

pub fn is<T: ObjectType>(&self) -> bool

Whether the object is of class T or a class derived from it.

pub fn downcast_ref<T: ObjectType>(&self) -> Option<&T>

Returns the object viewed as class T if it is one.

pub fn on_property_changed(&self, change: &FerroPropertyChangedEventArgs<'_>)

Invokes the on_property_changed virtual member.

pub fn inheritance_parent(&self) -> Option<Ref<FerroObject>>

The parent object that inherited property values are inherited from.

pub fn set_inheritance_parent(&self, value: impl Into<Nullable<FerroObject>>)

Sets the parent object that inherited property values are inherited from.

pub fn clear_value<T: PropertyValue>( &self, property: &'static StyledProperty<T>, )

Clears a property’s local value.

pub fn get_value<T: PropertyValue>( &self, property: &'static StyledProperty<T>, ) -> T

Gets a property value.

pub fn get_base_value<T: PropertyValue>( &self, property: &'static StyledProperty<T>, ) -> Option<T>

Gets a property’s base value: the value excluding animated values. Returns None if the value comes from inheritance or the default.

pub fn is_animating(&self, property: &FerroProperty) -> bool

Checks whether a property is animating.

pub fn is_set(&self, property: &FerroProperty) -> bool

Checks whether a styled property has a value assigned to it or a binding targeting it.

pub fn set_value<T: PropertyValue>( &self, property: &'static StyledProperty<T>, value: T, )

Sets a property value with local value priority.

pub fn set_value_with_priority<T: PropertyValue>( &self, property: &'static StyledProperty<T>, value: T, priority: BindingPriority, ) -> Option<Rc<dyn IDisposable>>

Sets a property value with the given priority. For priorities other than local value, disposing the returned handle removes the value.

pub fn set_current_value<T: PropertyValue>( &self, property: &'static StyledProperty<T>, value: T, )

Sets the value of a property without changing its value source.

This is used by a component that programmatically sets the value of one of its own properties without disabling an application’s declared use of the property: the effective value changes, but existing bindings and styles continue to work. The new value has the property’s current priority.

pub fn bind_binding( &self, property: &'static FerroProperty, binding: &dyn BindingBase, ) -> Rc<dyn BindingExpressionBase>

Binds a property to a binding. Returns the binding expression which represents the binding instance on this object.

pub fn bind_binding_with_anchor( &self, property: &'static FerroProperty, binding: &dyn BindingBase, anchor: Option<&Ref<FerroObject>>, ) -> Rc<dyn BindingExpressionBase>

Binds a property to a binding.

Some bindings need context to locate their source: a data context, named elements or resources. If this object is not an element, or is not yet attached to the tree, anchor provides that context.

pub fn indexer(&self, binding: &IndexerDescriptor) -> IndexerBinding

Gets a binding to a property of this object: the indexer taking an IndexerDescriptor (source[!Property] is source.indexer(&Property.bind())).

pub fn bind_indexer( &self, binding: &IndexerDescriptor, value: &dyn BindingBase, ) -> Rc<dyn BindingExpressionBase>

Binds the property of an IndexerDescriptor to a binding: the setter of the indexer (target[!Property] = binding is target.bind_indexer(&Property.bind(), &binding)).

pub fn set_and_raise<T: PropertyValue>( &self, property: &'static DirectPropertyBase<T>, field: &RefCell<T>, value: T, ) -> bool

Sets the backing field of a direct property, raising a change notification if the value changed. Returns true if it changed.

pub fn set_and_raise_cell<T: PropertyValue + Copy>( &self, property: &'static DirectPropertyBase<T>, field: &Cell<T>, value: T, ) -> bool

set_and_raise for Copy values stored in a Cell.

pub fn get_value_untyped(&self, property: &'static FerroProperty) -> BoxedValue

Gets a property value as an untyped value.

pub fn set_value_untyped( &self, property: &'static FerroProperty, value: &dyn Any, priority: BindingPriority, ) -> Option<Rc<dyn IDisposable>>

Sets a property from an untyped value, which must hold exactly the property’s value type or the unset marker.

set_current_value with an untyped value.

pub fn clear_value_untyped(&self, property: &'static FerroProperty)

Clears a property’s local value.

pub fn add_property_changed_handler( &self, handler: Rc<dyn Fn(&FerroPropertyChangedEventArgs<'_>)>, ) -> u64

Subscribes handler to property changes on this object and returns the token that remove_property_changed_handler takes: property_changed for a subscriber that keeps the object and the token itself, so that no handle is made.

pub fn remove_property_changed_handler(&self, token: u64) -> bool

Ends a subscription of add_property_changed_handler.

pub fn property_changed_subscriber_count(&self) -> usize

The number of subscribers to property changes on this object (a diagnostics member, used by tests to verify that subscriptions are released).

pub fn raise_property_changed<T: PropertyValue>( &self, property: &'static FerroProperty, old_value: Option<&T>, new_value: &T, priority: BindingPriority, is_effective_value: bool, )

Raises a property changed notification.

pub fn raise_direct_property_changed<T: PropertyValue>( &self, property: &'static DirectPropertyBase<T>, old_value: &T, new_value: &T, )

Raises a property changed notification for a direct property.

Trait Implementations

impl Deref for Animation

type Target = FerroObject

The resulting type after dereferencing.

fn deref(&self) -> &FerroObject

Dereferences the value.

impl FerroObjectImpl for Animation

fn constructed(this: &Self)

Called once, right after the object has been allocated. This is where constructor logic that needs a reference to the object runs. Overrides must call parent_constructed first.

fn on_property_changed_core( this: &Self, change: &FerroPropertyChangedEventArgs<'_>, )

Called for every property change on the object, including changes of non-effective (base) values. Overriding this is rarely needed; override on_property_changed instead.

fn on_property_changed(this: &Self, change: &FerroPropertyChangedEventArgs<'_>)

Called when the effective value of a property changes on the object.

fn update_data_validation( this: &Self, property: &'static FerroProperty, state: BindingValueType, error: Option<&BindingError>, )

Called to update the validation state for properties for which data validation is enabled.

impl ObjectType for Animation

type Parent = FerroObject

The base class. The root class is its own parent.

type VTable = <FerroObject as ObjectType>::VTable

The virtual table of the class.

fn vtable() -> &'static Self::VTable

The virtual table used by instances whose most-derived class is Self.

fn register_class()

The static initialisation of the class. The first call on a thread, after doing the same for the base class:
