# setNotShownAttribute(_:forGlyphRange:)

Sets whether the specified glyphs are not shown.

## Declaration

```swift
func setNotShownAttribute(_ flag: Bool, forGlyphRange glyphRange: NSRange)
```

## Parameters

- `flag`: doc://com.apple.documentation/documentation/Swift/true if the glyphs in glyphRange are not shown, doc://com.apple.documentation/documentation/Swift/false if they are shown.
- `glyphRange`: The range of glyphs in question.

## Discussion

Discussion For example, a tab or newline character doesn’t leave any marks; it just indicates where following glyphs are laid out. A subclass can override this method to interact with custom glyph storage.
