Gtktreeview + Drag & Drop : How to highliht destination row?

[khamul freesurf fr]

Hi,


I have a treeview and an iconview and doing some drag & drop from the
iconview to the treeview.
But when I drag an icon, Gtk creates a copy of that icon as a drag icon
and won't allow the user to select precisely a row of the treeview.

To be sure to select the good row, I would like to highlight the row
hovered by the cursor (like gtk_tree_view_set_hover_selection)?


How can I do this?
