GDK Reference Manual

gdk_fontset_load ()
GdkFont*gdk_fontset_load(gchar *fontset_name); 

　　Loads a fontset.

　　Currently this function will always return a new font, however, in the future, it may be changed to look up the font in a cache. You should make no assumptions about the initial reference count.

　　fontset_name : a comma-separated list of XLFDs describing the component fonts of the fontset to load.

　　Returns : a GdkFont, or NULL if the fontset could not be loaded.

gdk_font_ref ()
GdkFont*gdk_font_ref(GdkFont *font); 

　　Increase the reference count of a count by one.

　　font : a GdkFont

　　Returns : font

gdk_font_unref ()
voidgdk_font_unref(GdkFont *font); 

　　Decrease the reference count of a count by one. If the result is zero, destroys the font.

　　font : a GdkFont

gdk_font_id ()
gintgdk_font_id (const GdkFont *font); 

　　Returns the X Font ID for the given font.

　　font : a GdkFont.

　　Returns : the numeric X Font ID

gdk_font_equal ()
gintgdk_font_equal(const GdkFont *fonta,const GdkFont *fontb); 

　　Compares two fonts for equality. Single fonts compare equal if they have the same X font ID. This operation does not currently work correctly for fontsets.

　　fonta : a GdkFont.

　　fontb : another GdkFont.

　　Returns : TRUE if the fonts are equal.

gdk_string_extents ()
voidgdk_string_extents(GdkFont *font,const gchar *string,gint *lbearing,
gint *rbearing,gint *width,gint *ascent,gint *descent); 

　　Returns the metrics of a NULL-terminated string.

　　font : a GdkFont.

　　string : the NULL-terminated string to measure.

　　lbearing : the left bearing of the string.

　　rbearing : the right bearing of the string.

　　width : the width of the string.

　　ascent : the ascent of the string.

　　descent : the descent of the string.

gdk_text_extents ()
voidgdk_text_extents(GdkFont *font,
const gchar *text,gint text_length,gint *lbearing,gint *rbearing,
gint *width,gint *ascent,gint *descent); 

　　Returns the metrics of a string.

　　font : a GdkFont

　　text : the text to measure

　　text_length : the length of the text in bytes. (If the font is a 16-bit font, this is twice the length of the text in characters.)

　　lbearing : the left bearing of the string.

　　rbearing : the right bearing of the string.

　　width : the width of the string.

　　ascent : the ascent of the string.

　　descent : the descent of the string.

gdk_text_extents_wc ()
voidgdk_text_extents_wc (GdkFont *font,const GdkWChar *text,
gint text_length,gint *lbearing,gint *rbearing,
gint *width,gint *ascent,gint *descent); 

　　Returns the metrics of a string of wide characters.

　　font : a GdkFont

　　text : the text to measure.

　　text_length : the length of the text in character.

　　lbearing : the left bearing of the string.

　　rbearing : the right bearing of the string.

　　width : the width of the string.

　　ascent : the ascent of the string.

　　descent : the descent of the string.

gdk_string_width ()
gintgdk_string_width(GdkFont *font,const gchar *string); 

　　Determine the width of a NULL-terminated string. (The distance from the origin of the string to the point where the next string in a sequence of strings should be drawn)

　　font : a GdkFont

　　string : the NULL-terminated string to measure

　　Returns : the width of the string in pixels.

gdk_text_width ()
gintgdk_text_width(GdkFont *font,const gchar *text,gint text_length);
