Struct Setter 

pub struct Setter { /* private fields */ }

A setter for a Style.

A setter describes what will take place when the requirements for a style are met: it sets a property to a value, binds it to a source of values or sets it to the result of a template.

Implementations

impl Setter

pub fn empty() -> Rc<Self>

Creates a setter without a property or value.

pub fn new<T: PropertyValue>( property: &'static StyledProperty<T>, value: T, ) -> Rc<Self>

Creates a setter that sets a styled property to a value.

pub fn new_untyped( property: &'static FerroProperty, value: BoxedValue, ) -> Rc<Self>

Creates a setter that sets a property to an untyped value, which must hold exactly the property’s value type.

pub fn new_binding( property: &'static FerroProperty, source: Rc<dyn IObservable<BoxedValue>>, ) -> Rc<Self>

Creates a setter that binds a property to a source of values.

pub fn new_binding_base( property: &'static FerroProperty, binding: Rc<dyn BindingBase>, ) -> Rc<Self>

Creates a setter that binds a property with a binding (a compiled, string-path, template or multi binding).

pub fn new_template( property: &'static FerroProperty, template: Rc<dyn ITemplate>, ) -> Rc<Self>

Creates a setter that sets a property to the object built by a template.

pub fn with_value( property: &'static FerroProperty, value: SetterValue, ) -> Rc<Self>

Creates a setter for a property with the given kind of value.

pub fn property(&self) -> Option<&'static FerroProperty>

The property to set.

pub fn set_property(&self, value: Option<&'static FerroProperty>)

pub fn value(&self) -> Option<SetterValue>

The property value.

pub fn set_value(&self, value: Option<SetterValue>)

pub fn set_setter_value(&self, value: &dyn ISetterValue, boxed: BoxedValue)

Sets a plain value that wants to be notified that it has become a setter value. boxed is the value as it will be set on the property.

Trait Implementations

impl Default for Setter

fn default() -> Self

Returns the “default value” for a type.

impl Display for Setter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IAnimationSetter for Setter

fn property(&self) -> Option<&'static FerroProperty>

The property the setter targets.

fn set_property(&self, value: Option<&'static FerroProperty>)

fn value(&self) -> Option<SetterValue>

The value of the setter: a plain value holding exactly the value type of the property, or a source of such values.

fn set_value(&self, value: Option<SetterValue>)

fn as_any(&self) -> Option<&dyn Any>

The implementing value, for casting to its concrete type (as_any()?.downcast_ref::<T>()): the equivalent of is/as on the contract. None for an implementation that does not expose itself.

impl ISetterInstance for Setter

impl MarkupTyped for Setter

const MARKUP: &'static MarkupType

The markup metadata of the type.

impl PartialEq for Setter

Compares by identity (reference equality), as the reference type this mirrors.

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl SetterBase for Setter

fn as_any(&self) -> Option<&dyn Any>

The implementing value, for casting to its concrete type (as_any()?.downcast_ref::<T>()): the equivalent of is/as on the contract. None for an implementation that does not expose itself.
