# drawStrikethrough(forGlyphRange:strikethroughType:baselineOffset:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:)

Draws a strikethrough for the specified glyphs.

## Declaration

```swift
func drawStrikethrough(forGlyphRange glyphRange: NSRange, strikethroughType strikethroughVal: NSUnderlineStyle, baselineOffset: CGFloat, lineFragmentRect lineRect: NSRect, lineFragmentGlyphRange lineGlyphRange: NSRange, containerOrigin: NSPoint)
```

## 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.appkit/documentation/AppKit/NSLayoutManager/lineFragmentRect(forGlyphAt:effectiveRange:)).
- `strikethroughVal`: The style of strikethrough to draw. This value is a mask derived from the value for doc://com.apple.documentation/documentation/Foundation/NSAttributedString/Key/underlineStyle—for example, (NSUnderlinePatternDash | NSUnderlineStyleThick). Subclasses can define custom strikethrough styles.
- `baselineOffset`: Indicates how far above the text baseline the underline should be drawn.
- `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 is invoked automatically by strikethroughGlyphRange(_:strikethroughType:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:); you should rarely need to invoke it directly. This method’s strikethroughVal parameter does not take account of any setting forNSUnderlineByWordMask because that’s taken care of by underlineGlyphRange(_:underlineType:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:).
