doubleAction
The action sent to the target of the receiver when the user double-clicks a cell.
Declaration
var doubleAction: Selector? { get set }Discussion
The double-click action of an NSMatrix is sent after the appropriate single-click action (for the NSCell clicked, or for the NSMatrix if the NSCell doesn’t have its own action). If there is no double-click action and the NSMatrix doesn’t ignore multiple clicks, the single-click action is sent twice. If the value of this property is a non-nil selector, this property also sets ignoresMultiClick to false; otherwise, it leaves ignoresMultiClick unchanged.
