# strikethroughGlyphRange(_:strikethroughType:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:)

Calculates and draws strikethrough for the specified glyphs.

## Declaration

```swift
func strikethroughGlyphRange(_ glyphRange: NSRange, strikethroughType strikethroughVal: NSUnderlineStyle, lineFragmentRect lineRect: CGRect, lineFragmentGlyphRange lineGlyphRange: NSRange, containerOrigin: CGPoint)
```

## Parameters

- `glyphRange`: The range of glyphs for which to draw a strikethrough. The range must belong to a single line fragment rectangle (as returned by doc://com.apple.uikit/documentation/UIKit/NSLayoutManager/lineFragmentRect(forGlyphAt:effectiveRange:)).
- `strikethroughVal`: The style of underlining to draw. This value is a mask derived from the value for doc://com.apple.uikit/documentation/UIKit/NSUnderlineStyleAttributeName—for example, (NSUnderlinePatternDash | NSUnderlineStyleThick | NSUnderlineByWordMask). Subclasses can define custom underlining styles.
- `lineRect`: The line fragment rectangle containing the glyphs to draw strikethrough for.
- `lineGlyphRange`: The range of all glyphs within lineRect.
- `containerOrigin`: The origin of the line fragment rectangle’s NSTextContainer in its NSTextView.

## Discussion

Discussion This method determines which glyphs actually need to have a strikethrough drawn based on strikethroughVal. After determining which glyphs to draw strikethrough on, this method invokes drawStrikethrough(forGlyphRange:strikethroughType:baselineOffset:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:) for each contiguous range of glyphs that requires it.
