A Boolean value indicating whether the cell sends its action message continuously during mouse tracking.
- macOS 10.0+
When the value of this property is YES, the cell’s action message is sent continuously during mouse tracking. In practice, the continuous delivery of action messages has meaning only for
NSAction and its subclasses, which implement the target/action mechanism. Some
NSControl subclasses, notably
NSMatrix, send a default action to a default target when a cell doesn’t provide a target or action.
