NSSpringLoadingHighlight
A group of constants that indicate a highlighting style for your app’s user interface to display during a spring-loading operation.
Declaration
enum NSSpringLoadingHighlightOverview
The springLoadingHighlight method provides one of these constant values.
Do not use highlighting as a means to determine whether spring-loading has actually been activated or deactivated. The springLoadingActivated(_:draggingInfo:) method alerts your app when spring-loading activation occurs.
