Instance Property


The default action-message selector associated with the control.


@property SEL action;


This property contains the action message selector of the receiver's cell. Controls that support multiple cells (such as NSMatrix and NSForm) must supply the appropriate action-message selector in this property. Specify NULL to prevent action messages from being sent to the receiver's target.

If you want the action-message selector for a control that has multiple cells, it is better to get the selector directly from the cell's own action property.
