With the base Pango interfaces, you could create a + * #PangoAttrList and apply it to the text; the problem is that you'd + * need to apply attributes to some numeric range of characters, for + * example "characters 12-17." This is broken from an internationalization + * standpoint; once the text is translated, the word you wanted to + * italicize could be in a different position. + * + * The solution is to include the text attributes in the string to be + * translated. Pango provides this feature with a small markup language. + * You can parse a marked-up string into the string text plus a + * #PangoAttrList using either of pango_parse_markup() or + * pango_markup_parser_new(). + * + * A simple example of a marked-up string might be: + * |[ + * <span foreground="blue" size="x-large">Blue text</span> is <i>cool</i>! + * ]| + * + * Pango uses #GMarkup to parse this language, which means that XML + * features such as numeric character entities such as &#169; for + * © can be used too. + * + * The root tag of a marked-up document is <markup>, but + * pango_parse_markup()allows you to omit this tag, so you will most + * likely never need to use it. The most general markup tag is <span>, + * then there are some convenience tags. + * + * <span> has the following attributes: + * + * font_desc + * : A font description string, such as "Sans Italic 12". + * See pango_font_description_from_string() for a description of the + * format of the string representation . Note that any other span + * attributes will override this description. So if you have "Sans Italic" + * and also a style="normal" attribute, you will get Sans normal, + * not italic. + * + * font_family + * : A font family name + * + * font_size, size + * : Font size in 1024ths of a point, or one of the absolute + * sizes 'xx-small', 'x-small', 'small', 'medium', 'large', + * 'x-large', 'xx-large', or one of the relative sizes 'smaller' + * or 'larger'.
