TODO(https://fxbug.dev/42170326): Remove deprecated methods and move to provider.fidl.

Variants

GetFont

Deprecated. See GetTypeface.

Returns font that matches specified request.

Fields

request: Request

responder: ProviderGetFontResponder

GetFamilyInfo

Deprecated. See GetFontFamilyInfo.

Returns information for the specified font family or null if there is no family with the specified name. This function respects family name aliases and ignores case, so request for “robotoSLAB” will return FamilyInfo for “Roboto Slab”.

Fields

family: String

responder: ProviderGetFamilyInfoResponder

GetTypeface

Returns a typeface that matches the specified request, or an empty table if no matching face is found. (The latter is more likely to happen if TypefaceRequestFlags.EXACT_FAMILY is used to disable fallbacks.)

Fields

request: TypefaceRequest

responder: ProviderGetTypefaceResponder

GetFontFamilyInfo

Returns information for the specified font family, or an empty table if there is no family with the specified name.

This function respects family name aliases and ignores case. For example, “RobotoSlab” is an alias for the canonical name “Roboto Slab”. A request for “robotoSLAB” would return the FontFamilyInfo for “Roboto Slab” due to the case-insensitivity and alias resolution.

Fields

family: FamilyName

responder: ProviderGetFontFamilyInfoResponder

RegisterFontSetEventListener

Register a listener to be notified when the set of available fonts or mappings has changed. A client can register as many listeners as it wishes.

To unregister, close the channel.

Fields

listener: ClientEnd<FontSetEventListenerMarker>

responder: ProviderRegisterFontSetEventListenerResponder
