setFontMap_
Sets a custom font map to use for this 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.
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);Content copied to clipboard
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:
context = gtk_widget_get_pango_context (label);
