NSFont

The NSFont class allows control of the fonts used for displaying text anywhere on the screen. The primary methods for getting a particular font are +fontWithName:matrix: and +fontWithName:size: which take the name and size of a particular font and return the NSFont object associated with that font. In addition there are several convenience mathods which make it easier to get certain types of fonts.

In particular, there are several methods to get the standard fonts used by the Application to display text for a partiuclar purpose. See the class methods listed below for more information. These default fonts can be set using the user defaults system. The default font names available are:

The default sizes are:

Font sizes list with (none) default to NSFontSize.

Method summary

boldSystemFontOfSize: 

+ (NSFont*) boldSystemFontOfSize: (CGFloat)fontSize;
Availability: OpenStep

Returns the default bold font for use in menus and heading in standard gui components. If fontSize is <= 0, the default size is used.

controlContentFontOfSize: 

+ (NSFont*) controlContentFontOfSize: (CGFloat)fontSize;
Availability: MacOS-X 10.0.0

Description forthcoming.

fontWithDescriptor: size: 

+ (NSFont*) fontWithDescriptor: (NSFontDescriptor*)descriptor size: (CGFloat)size;
Availability: MacOS-X 10.4.0

Description forthcoming.

fontWithDescriptor: size: textTransform: 

+ (NSFont*) fontWithDescriptor: (NSFontDescriptor*)descriptor size: (CGFloat)size textTransform: (NSAffineTransform*)transform;
Availability: MacOS-X 10.4.0

Description forthcoming.

fontWithDescriptor: textTransform: 

+ (NSFont*) fontWithDescriptor: (NSFontDescriptor*)descriptor textTransform: (NSAffineTransform*)transform;
Availability: MacOS-X 10.4.0

Description forthcoming.

fontWithName: matrix: 

+ (NSFont*) fontWithName: (NSString*)aFontName matrix: (const CGFloat*)fontMatrix;
Availability: OpenStep

Returns an autoreleased font with name aFontName and matrix fontMatrix.

The fontMatrix is a standard size element matrix as used in PostScript to describe the scaling of the font, typically it just includes the font size as [fontSize 0 0 fontSize 0 0]. You can use the constant NSFontIdentityMatrix in place of [1 0 0 1 0 0]. If NSFontIdentityMatrix, then the font will automatically flip itself when set in a flipped view.

fontWithName: size: 

+ (NSFont*) fontWithName: (NSString*)aFontName size: (CGFloat)fontSize;
Availability: OpenStep

Returns an autoreleased font with name aFontName and size fontSize.

Fonts created using this method will automatically flip themselves when set in a flipped view.
