Note that this can be a different string than what you set with gtk_font_selection_dialog_set_font_name(), as the font selection widget may normalize font names and thus return a string with a different structure. For example, "Helvetica Italic Bold 12" could be normalized to "Helvetica Bold Italic 12". Use pango_font_description_equal() if you want to compare two font descriptions. font is selected. You must free this string with g_free().
