catching unfocus of a treeview row

[Emmanuel Saracco <esaracco noos fr>]

hi,

I would like to detect a focus lost on a treeview row. I catch the
"cursor_changed" signal and test the state of the row in my callback
with "gtk_tree_selection_iter_is_selected", but it always return me a
true value if the row was previously selected, so I could not known the
real state of a given row.

what is the right way to do that?

bye
