# setLocation(_:forStartOfGlyphRange:)

Sets the location for the first glyph in the specified range.

```
func setLocation(_ location: NSPoint, forStartOfGlyphRange glyphRange: NSRange)
```

## Parameters

`location`

The location to which the first glyph is set, relative to the origin of the glyph’s line fragment origin.

`glyphRange`

The glyphs whose location is set.

## Discussion

Setting the location for a glyph range implies that its first glyph is not nominally spaced with respect to the previous glyph. In the course of layout, all glyphs should end up being included in a range passed to this method, but only glyphs that start a new nominal range should be at the start of such ranges. The first glyph in a line fragment should always start a new nominal range. Glyph locations are given relative to their line fragment rectangle’s origin.

Before setting the location for a glyph range, you must specify the text container with [`setTextContainer(_:forGlyphRange:)`](/documentation/AppKit/NSLayoutManager/setTextContainer(_:forGlyphRange:)) and the line fragment rectangle with [`setLineFragmentRect(_:forGlyphRange:usedRect:)`](/documentation/AppKit/NSLayoutManager/setLineFragmentRect(_:forGlyphRange:usedRect:)).

This method is used by the layout mechanism and should be invoked only during typesetting, in almost all cases only by the typesetter. For example, a custom typesetter might invoke it.
