To use bauhaus in preferences, add the below in generate_prefs.xsl:

<xsl:text>const gchar *string_list[] = {</xsl:text>
<xsl:for-each select="./type/enum/option">
  <xsl:text>N_("</xsl:text>
    <xsl:value-of select="."/>      
  <xsl:text>"), </xsl:text>
</xsl:for-each>
<xsl:text>NULL };</xsl:text>
<xsl:text>

widget = dt_bauhaus_combobox_new(NULL);
dt_bauhaus_combobox_set_selected_text_align(widget, DT_BAUHAUS_COMBOBOX_ALIGN_LEFT);
dt_bauhaus_combobox_add_list(widget, NULL, string_list);

dt_bauhaus_combobox_add_list should pick up alignment from widget text_align. but really, prefs should store strings (including translation codes) in introspection compatible format.
