FontFaceSet

sealed class FontFaceSet : EventTarget, MutableSetLike<FontFace> (source)

The FontFaceSet interface of the CSS Font Loading API manages the loading of font-faces and querying of their download status.

Properties

var onloading: EventHandler<FontFaceSetLoadEvent, FontFaceSet, FontFaceSet>?

var onloadingdone: EventHandler<FontFaceSetLoadEvent, FontFaceSet, FontFaceSet>?

var onloadingerror: EventHandler<FontFaceSetLoadEvent, FontFaceSet, FontFaceSet>?

val ready: Promise<FontFaceSet>

The ready read-only property of the FontFaceSet interface returns a Promise that resolves to the given FontFaceSet.

abstract override val size: Int

val status: FontFaceSetLoadStatus

The status read-only property of the FontFaceSet interface returns the loading state of the fonts in the set.

Functions

abstract fun add(value: FontFace)

fun check(font: String, text: String = definedExternally): Boolean

The check() method of the FontFaceSet returns true if you can render some text using the given font specification without attempting to use any fonts in this FontFaceSet that are not yet fully loaded. This means you can use the font specification without causing a font swap.

abstract fun clear()

abstract fun delete(value: FontFace): Boolean

open fun dispatchEvent(event: Event): Boolean

abstract fun entries(): JsIterator<Tuple2<FontFace, FontFace>>

abstract fun forEach(action: (item: FontFace) -> Unit)

open operator fun get(key: Symbol.iterator): () -> JsIterator<FontFace>

abstract override fun has(key: FontFace): Boolean

abstract fun keys(): JsIterator<FontFace>

inline suspend fun FontFaceSet.load(font: String): ReadonlyArray<FontFace>

inline suspend fun FontFaceSet.load(font: String, text: String): ReadonlyArray<FontFace>

The load() method of the FontFaceSet forces all the fonts given in parameters to be loaded.

fun loadAsync(font: String, text: String = definedExternally): Promise<ReadonlyArray<FontFace>>

The load() method of the FontFaceSet forces all the fonts given in parameters to be loaded.

abstract fun values(): JsIterator<FontFace>

fun <T : Event> when(type: EventType<T>, options: ObservableEventListenerOptions?): Observable<T>
