The font class
Copyright: (C) 1996 Free Software Foundation, Inc.
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:
NSBoldFont Helvetica-Bold (System bold font)
NSControlContentFont System font
NSFont Helvetica (System Font)
NSLabelFont System font
NSMenuFont System font
NSMenuBarFont System font
NSMessageFont System font
NSPaletteFont System bold font
NSTitleBarFont System bold font
NSToolTipsFont System font
NSUserFixedPitchFont Courier
NSUserFont System font
The default sizes are:
NSBoldFontSize (none)
NSControlContentFontSize (none)
NSFontSize 12 (System Font Size)
NSLabelFontSize (none)
NSMenuFontSize (none)
NSMiniFontSize 8
NSMessageFontSize (none)
NSPaletteFontSize (none)
NSSmallFontSize 10
NSTitleBarFontSize (none)
NSToolTipsFontSize (none)
NSUserFixedPitchFontSize (none)
NSUserFontSize (none)
Font sizes list with (none) default to NSFontSize.

Instance Variables
+ (
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.

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.
+ (
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.
