How to align the text of a Listbox to the right

[Leonardo da Vinci]

I have to use a Listbox that shows a list of entries. Every entry is a
char string quite long in size and I cannot set "width" to a large
value due to limitations of screen resolution. The rightmost part is
more important, so I thought that I could show only the end of the
string by aligning the field to the right.
