Properties

attributes

val attributes: MutableMap<String, Any?>

This is a delicate API that exposes the raw attribute backing without any type safety. This is frequently used by the internals of Krayon, but is likely something you shouldn't use as a library consumer. That said, it's still exposed for the cases where it's necessary. When using this, be very careful not to clobber existing attributes.

children

val children: List<Element>

data

var data: Any?

kind

var kind: String?

Analogous to an HTML class, except you can only have one.

onClickFallback

var onClickFallback: () -> Unit?

If set, this callback is invoked when onClick is called but no descendant element handles that event.

parent

open var parent: Element?

tag

open override val tag: String

Functions

appendChild

open fun <E : Element> appendChild(child: E): E

draw

open override fun draw(kanvas: Kanvas)

insertBefore

open fun <E : Element> insertBefore(child: E, reference: Element?): E

matches

fun matches(selector: ElementSelector<*>): Boolean

onClick

fun onClick(isPointInPath: IsPointInPath, x: Float, y: Float)

Entry point for dispatching click events. Usually you won't need to call this, and it will be handled by your platform-specific ElementView.

onHover

fun onHover(isPointInPath: IsPointInPath, x: Float, y: Float)

Entry point for dispatching hover events, both start and move. Usually you won't need to call this, and it will be handled by your platform-specific ElementView.

onHoverEnded

fun onHoverEnded()

Entry point for dispatching hover-end events. Usually you won't need to call this, and it will be handled by your platform-specific ElementView.

query

open fun <E : Element> query(selector: ElementSelector<E>): E?

queryAll

open fun <E : Element> queryAll(selector: ElementSelector<E>): Sequence<E>
