Instance Method

notShownAttribute(forGlyphAt:)

Indicates whether the glyph at the given index is one that isn’t shown.

Declaration

func notShownAttribute(forGlyphAt glyphIndex: Int) -> Bool

Parameters

glyphIndex

Index of the glyph.

Return Value

true if the glyph at glyphIndex is not shown; otherwise false.

Discussion

Some glyphs are not shown. For example, a tab, newline, or attachment glyph is not shown; it just affects the layout of following glyphs or locates the attachment graphic. Space characters, however, typically are shown as glyphs with a displacement, although they leave no visible marks.

This method causes glyph generation and layout for the line fragment containing the specified glyph, or if noncontiguous layout is not enabled, up to and including that line fragment.

Raises an NSRangeException if glyphIndex is out of bounds.
