# NSControlCharacterWhitespaceAction

An action that programmatically changes the white space around the glyph.

## Declaration

```swift
var NSControlCharacterWhitespaceAction: Int { get }
```

## Discussion

Discussion The width for a glyph with this action is determined by the delegate method layoutManager(_:boundingBoxForControlGlyphAt:for:proposedLineFragment:glyphPosition:characterIndex:) if the method is implemented; otherwise, it’s the same as NSControlCharacterZeroAdvancementAction.
