Struct ClickableElement 

pub struct ClickableElement { /* private fields */ }

Element that creates and updates clickable nodes.

Implementations

impl ClickableElement

pub fn new(on_click: impl Fn(Point) + 'static) -> Self

pub fn with_handler(on_click: Rc<dyn Fn(Point)>) -> Self

Trait Implementations

impl Clone for ClickableElement

fn clone(&self) -> ClickableElement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClickableElement

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

Formats the value using the given formatter.

impl Eq for ClickableElement

impl Hash for ClickableElement

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl ModifierNodeElement for ClickableElement

type Node = ClickableNode

fn create(&self) -> Self::Node

Creates a new modifier node instance for this element.

fn update(&self, node: &mut Self::Node)

Brings an existing modifier node up to date with the element’s data.

fn capabilities(&self) -> NodeCapabilities

Returns the capabilities of nodes created by this element. Override this to indicate which specialized traits the node implements.

fn always_update(&self) -> bool

Whether this element requires update to be called even if eq returns true.

fn key(&self) -> Option<u64>

Optional key used to disambiguate multiple instances of the same element type.

fn inspector_name(&self) -> &'static str

Human readable name surfaced to inspector tooling.

fn inspector_properties(&self, _inspector: &mut dyn FnMut(&'static str, String))

Records inspector properties for tooling.

fn auto_invalidate_on_update(&self) -> bool

Whether modifier reconciliation should request capability-wide invalidations after updating an existing node.

fn update_invalidation_kind(&self) -> Option<InvalidationKind>

Optional targeted invalidation requested after updating an existing node.

impl PartialEq for ClickableElement

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
