# setState(_:atRow:column:)

Sets the state of the cell at specified location.

## Declaration

```swift
func setState(_ value: Int, atRow row: Int, column col: Int)
```

## Parameters

- `value`: The value to assign to the cell.
- `row`: The row in which the cell is located.
- `col`: The column in which the cell is located.

## Discussion

Discussion For radio-mode matrices, if value is nonzero the specified cell is selected before its state is set to value. If value is 0 and the receiver is a radio-mode matrix, the currently selected cell is deselected (providing that empty selection is allowed). This method redraws the affected cell.
