# deselectAllCells()

Deselects all cells in the receiver and, if necessary, redisplays the receiver.

```
func deselectAllCells()
```

## Discussion

If the selection mode is `NSRadioModeMatrix` and empty selection is not allowed, this method does nothing.

## See Also

[`var mode: NSMatrix.Mode`](/documentation/AppKit/NSMatrix/mode-swift.property)

The selection mode of the receiver.

[`var allowsEmptySelection: Bool`](/documentation/AppKit/NSMatrix/allowsEmptySelection)
