onDraw

readonly onDraw: ReadonlySubEvent<MapLocationTextLabel, AbstractMapTextLabelDrawData>

Defined in: src/sdk/components/map/MapTextLabel.ts:157

An event that notifies subscribers when this label is drawn (when draw() is called). The sender of the event is this label. The event data describes the draw operation that triggered the event. When the draw operation did not draw a visible label, the event is triggered with all NaN values.

The data object passed to event handlers is only guaranteed to be valid at the moment the handler is called. If a handler needs to retain the data past this moment, then it is recommended that a copy of the data be made.
