# doubleAction

The action sent to the target of the receiver when the user double-clicks a cell.

```
var doubleAction: Selector? { get set }
```

## Discussion

The double-click action of an [`NSMatrix`](/documentation/AppKit/NSMatrix) is sent after the appropriate single-click action (for the [`NSCell`](/documentation/AppKit/NSCell) clicked, or for the [`NSMatrix`](/documentation/AppKit/NSMatrix) if the [`NSCell`](/documentation/AppKit/NSCell) doesn’t have its own action). If there is no double-click action and the [`NSMatrix`](/documentation/AppKit/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 <doc://com.apple.documentation/documentation/Swift/false>; otherwise, it leaves `ignoresMultiClick` unchanged.
