Struct TargetPropertyPath 

pub struct TargetPropertyPath { /* private fields */ }

The target of a Setter of a visual state: an object and a property of it.

Markup writes it as the text of Setter.Target: Element.Property or Element.(Owner.Property) for an attached property. The compiler keeps the name of the element (target_name) and resolves the property against the type of the element; the property is the property of the setter. The element is found by its name in the name scope of the template or the document when the state is applied, as WinUI’s CTargetPropertyPath does (m_targetName, ResolveTargetForVisualStateSetter), so a setter may name an element declared after it. An explicit target object, set in code or markup, is used instead of the name (WinUI’s manual target).

The target is held weakly: a setter of a visual state usually targets an element of the tree that holds the visual states, and so the setter would keep that tree alive.

Implementations

impl TargetPropertyPath

pub fn empty() -> Rc<Self>

Creates a path without a target or a property.

pub fn new(target: &FerroObject, property: &'static FerroProperty) -> Rc<Self>

Creates the path of property of target (WinUI’s constructor that takes a property, with the target set).

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

The target object, if it is set and alive.

pub fn set_target(&self, value: Option<Ref<FerroObject>>)

pub fn target_name(&self) -> String

The name of the target element, resolved in a name scope when the setter applies; empty when the target is an explicit object or not set.

pub fn set_target_name(&self, value: impl Into<String>)

pub fn path(&self) -> String

The text of the path of the property (Property or (Owner.Property)), as markup wrote it.

pub fn set_path(&self, value: impl Into<String>)

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

The property of the target, when the path is resolved. A setter of a visual state keeps the resolved property in its own Property.

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