Overview

Important: The information in this document is obsolete and should not be used for new development.

NSSimpleHorizontalTypesetter is deprecated in Mac OS X version 10.4. Use NSATSTypesetter instead.

In Mac OS X version 10.2 and earlier, by default, NSLayoutManager used this class to perform line layout, which includes word wrapping, hyphenation, and line breaking. NSSimpleHorizontalTypesetter performs what is actually fairly complex left-to-right typesetting with some support for nonspacing marks. See layoutGlyphsInLayoutManager:startingAtGlyphIndex:maxNumberOfLineFragments:nextGlyphIndex: for more information.

Constants

NSLayoutStatus

These constants are returned from the method layoutGlyphsInHorizontalLineFragment:baseline: to indicate the current status of layout.

typedef enum _NSLayoutStatus {
   NSLayoutNotDone = 0,
   NSLayoutDone,
   NSLayoutCantFit,
   NSLayoutOutOfGlyphs
} NSLayoutStatus;

Constants

NSLayoutNotDone

Indicates that not all glyphs are laid yet, but all glyphs laid out so far fit within the given line fragment rectangle.

Available in Mac OS X v10.0 and later.

Declared in NSSimpleHorizontalTypesetter.h.

NSLayoutDone

Indicates that layout is complete and all glyphs fit within the given line fragment rectangle.

Available in Mac OS X v10.0 and later.

Declared in NSSimpleHorizontalTypesetter.h.

NSLayoutCantFit

Indicates that a glyph wouldn’t fit in the line fragment rectangle.

Available in Mac OS X v10.0 and later.

Declared in NSSimpleHorizontalTypesetter.h.

NSLayoutOutOfGlyphs

Indicates that layout is complete and there are no more glyphs to lay out.

Available in Mac OS X v10.0 and later.

Declared in NSSimpleHorizontalTypesetter.h.
