NoDataComplicationData

class NoDataComplicationData : ComplicationData


Type that can be sent by any complication data source, regardless of the configured type, when the complication data source has no data to be displayed. If no placeholder is included then watch faces may choose whether to render this in some way or leave the slot empty.

If a placeholder is included than its expected that it will be rendered. Its suggested the watch face renders the placeholder elements (text, title, smallImage, etc...) using solid grey blocks. Any non-placeholder elements included in placeholder must be rendered normally.

Some watchfaces may not support placeholders and in that case the NoDataComplicationData will be treated as being empty.
