Formating text in treeview

["Arthur Maciel" <arthurmaciel gmail com>]

Hi there.
Is there any way to format the text that is presented in a treeview to
contain something like (please, substitute tags with formatting in
your mind :-) :

PASSOS, L. M. M.; CHAVES, M. <BOLD> Alegria de saber: matemática,
segunda série, primeiro grau </BOLD> . <UNDERLINE> São Paulo:
Scipione, 1995. 136 p. </UNDERLINE>

Thanks in advance.
Regards,
Arthur
