Responds to a mouse-down event.
- macOS 10.0+
The mouse-down event.
A mouse-down event in a text cell initiates editing mode. A double click in any cell type except a text cell sends the double-click action of the receiver (if there is one) in addition to the single-click action.
Your code should never invoke this method, but you may override it to implement different mouse tracking than
NSMatrix does. The response of the receiver depends on its selection mode, as explained in the class description.
