gtk-font-chooser-font-map (fontchooser)

fontchooser -- a gtk-font-chooser widget
fontmap -- a pango-font-map object, or nil

Accessor of the Pango font map of the font chooser widget.

The function gtk-font-chooser-font-map gets the custom font map of the font chooser widget, or nil if it does not have one. The function (setf gtk-font-chooser-font-map) sets a custom font map to use for the font chooser widget. A custom font map can be used to present application specific fonts instead of or in addition to the normal system fonts.

Since 3.18 The example from the C documentation uses the Fontconfig library for configuring and customizing font access. This library is not available for the Lisp binding.

FcConfig *config;
PangoFontMap *fontmap;


config = FcInitLoadConfigAndFonts ();
FcConfigAppFontAddFile (config, my_app_font_file);


fontmap = pango_cairo_font_map_new_for_font_type (CAIRO_FONT_TYPE_FT);
pango_fc_font_map_set_config (PANGO_FC_FONT_MAP (fontmap), config);


gtk_font_chooser_set_font_map (font_chooser, fontmap);    

Note that other GTK+ widgets will only be able to use the application specific font if it is present in the font map they use. The following code updates the font map for a gtk-label widget with fontmap.

(setf (pango-context-font-map (gtk-widget-pango-context label)) fontmap)
