A font is an object which determines the appearance of text. Fonts are
used for drawing text to a device context, and setting the appearance of
a window’s text. You can retrieve the current system font settings with
SystemSettings.
Note that because this class wraps a platform-specific GUI resource, you
shouldn’t create instances of it until the app is running; ie until
after you have called App#main_loop or App.run.
The possible constant values for the family parameter of Font
constructor are (the old names are for compatibility only):
The possible values for the weight parameter are (the old names
are for compatibility only):
The font flags which can be used during the font creation are:
The known font encodings are:
FONTENCODING_SYSTEM = -1, // system default FONTENCODING_DEFAULT, // current default encoding // ISO8859 standard defines a number of single-byte charsets FONTENCODING_ISO8859_1, // West European (Latin1) FONTENCODING_ISO8859_2, // Central and East European (Latin2) FONTENCODING_ISO8859_3, // Esperanto (Latin3) FONTENCODING_ISO8859_4, // Baltic (old) (Latin4) FONTENCODING_ISO8859_5, // Cyrillic FONTENCODING_ISO8859_6, // Arabic FONTENCODING_ISO8859_7, // Greek FONTENCODING_ISO8859_8, // Hebrew FONTENCODING_ISO8859_9, // Turkish (Latin5) FONTENCODING_ISO8859_10, // Variation of Latin4 (Latin6) FONTENCODING_ISO8859_11, // Thai FONTENCODING_ISO8859_12, // doesn’t exist currently, but put it // here anyhow to make all ISO8859 // consecutive numbers FONTENCODING_ISO8859_13, // Baltic (Latin7) FONTENCODING_ISO8859_14, // Latin8 FONTENCODING_ISO8859_15, // Latin9 (a.k.a.

, these are not defined
until the App’s main loop has begun.

Font overview, DC#set_font, DC#draw_text, DC#get_text_extent, FontDialog, SystemSettings
Returns an integer constant identifying the current application’s
default encoding. This is set by the OS, and may be changed by using
set_default_encoding
Returns the name of the current application’s default encoding. This is
returned as a string suitable for use with Ruby’s ‘iconv’ library.
Copy constructor, uses reference counting.
Font.new(%(arg-type)Integer% pointSize, FontFamily family, Integer style, FontWeight weight, Boolean underline = false, String faceName = "", FontEncoding encoding = FONTENCODING_DEFAULT) Font.new(%(arg-type)Size% pixelSize, FontFamily family, Integer style, FontWeight weight, Boolean underline = false, String faceName = "", FontEncoding encoding = FONTENCODING_DEFAULT)Creates a font object with the specified attributes.
FONTFAMILY_DEFAULT | Chooses a default font. |
FONTFAMILY_DECORATIVE | A decorative font. |
FONTFAMILY_ROMAN | A formal, serif font. |
FONTFAMILY_SCRIPT | A handwriting font. |
FONTFAMILY_SWISS | A sans-serif font. |
FONTFAMILY_MODERN | A fixed pitch font. |
FONTFAMILY_TELETYPE | A teletype font. |
FONTWEIGHT_NORMAL | Normal font. |
FONTWEIGHT_LIGHT | Light font. |
FONTWEIGHT_BOLD | Bold font. |
FONTENCODING_SYSTEM | Default system encoding. |
FONTENCODING_DEFAULT | Default application encoding: thisis the encoding set by calls to"set_default_encoding":#Font_setdefaultencoding and which may be set to,say, KOI8 to create all fonts by default with KOI8 encoding. Initially, thedefault application encoding is the same as default system encoding. |
FONTENCODING_ISO8859_1…15 | ISO8859 encodings. |
FONTENCODING_KOI8 | The standard Russian encoding for Internet. |
FONTENCODING_CP1250…1252 | Windows encodings similar to ISO8859 (but not identical). |
If the specified encoding isn’t available, no font is created
(see also font encoding overview).
If the desired font does not exist, the closest match will be chosen.
Under Windows, only scalable TrueType fonts are used.
See also DC#set_font, DC#draw_text
and DC#get_text_extent.
Sets the default font encoding, passing a valid Wx::FONTENCODING_XX
constant.
Font encoding overview,
get_default_encoding
Sets the default font encoding, passing an encoding name.
Font encoding overview,
get_default_encoding
Returns true
if the font is a fixed width (or monospaced) font,
false
if it is a proportional one or font is invalid.
Returns the typeface name associated with the font, or the empty string if there is no
typeface information.
Gets the font family. See Font#set_family for a list of valid
family identifiers.
Returns the platform-dependent string completely describing this font.
Returned string is always non-empty.
Note that the returned string is not meant to be shown or edited by the user: a typical
use of this function is for serializing in string-form a Font object.
Font#set_native_font_info,Font#get_native_font_info_user_desc
Returns a user-friendly string for this font object. Returned string is always non-empty.
Some examples of the formats of returned strings (which are platform-dependent) are in set_native_font_info_user_desc.
Font#get_native_font_info_desc
Gets the point size.
Gets the font style. See Font.new for a list of valid
styles.
Returns true if the font is underlined, false otherwise.
Gets the font weight. See Font.new for a list of valid
weight identifiers.

These functions take the same parameters as Font
constructor and return a new font object allocated on the heap.
Using New()
is currently the only way to directly create a font with
the given size in pixels on platforms other than MSW.
Returns true
if this object is a valid font, false
otherwise.
Sets the facename for the font.
Returns if the given face name exists; otherwise.
To avoid portability problems, don’t rely on a specific face, but specify the font family
instead or as well. A suitable font will be found on the end-user’s system. If both the
family and the facename are specified, Widgets will first search for the specific face,
and then for a font belonging to the same family.
Font#get_face_name, Font#set_family
Sets the font family.
FONTFAMILY_DEFAULT | Chooses a default font. |
FONTFAMILY_DECORATIVE | A decorative font. |
FONTFAMILY_ROMAN | A formal, serif font. |
FONTFAMILY_SCRIPT | A handwriting font. |
FONTFAMILY_SWISS | A sans-serif font. |
FONTFAMILY_MODERN | A fixed pitch font. |
FONTFAMILY_TELETYPE | A teletype font. |
Font#get_family, Font#set_face_name
Creates the font corresponding to the given native font description string and returns if
the creation was successful.
which must have been previously returned by
get_native_font_info_desc. If the string is
invalid, font is unchanged. This function is typically used for de-serializing a Font
object previously saved in a string-form.
Font#set_native_font_info_user_desc
Creates the font corresponding to the given native font description string and returns if
the creation was successful.
Unlike set_native_font_info, this function accepts
strings which are user-friendly.
Examples of accepted string formats are:
Generic syntax | Example | |
on | GTK2: @$[FACE-NAME]$ $[bold]$ $[oblique | italic]$ $[POINTSIZE]$@Monospace bold 10 |
on | MSW: @$[light | bold]$ $[italic]$ $[FACE-NAME]$ $[POINTSIZE]$ $[ENCODING]$@Tahoma 10 WINDOWS-1252 |
on | Mac: FIXMEFIXME |
For more detailed information about the allowed syntaxes you can look at the documentation of the native API used for font-rendering (e.g. pango_font_description_from_stringhttp://developer.gnome.org/doc/API/2.0/pango/pango-Fonts.html\#pango-font-description-from-string).
Sets the point size.
Sets the font style.
Sets underlining.
Sets the font weight.
FONTWEIGHT_NORMAL | Normal font. |
FONTWEIGHT_LIGHT | Light font. |
FONTWEIGHT_BOLD | Bold font. |
