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

Draws a strikethrough for the specified glyphs.

```
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 [`lineFragmentRect(forGlyphAt:effectiveRange:)`](/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

This method is invoked automatically by [`strikethroughGlyphRange(_:strikethroughType:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:)`](/documentation/AppKit/NSLayoutManager/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 for[`NSUnderlineByWordMask`](/documentation/AppKit/NSUnderlineByWordMask) because that’s taken care of by [`underlineGlyphRange(_:underlineType:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:)`](/documentation/AppKit/NSLayoutManager/underlineGlyphRange(_:underlineType:lineFragmentRect:lineFragmentGlyphRange:containerOrigin:)).
