I active the EnterNotifyEvent for the treeview but it works only for
the entire of the widget.
See [1] for a patch against Nautilus which does what you want.
The interesting thing you have to grasp is
a) you only have motion notify events inside a tree view widget
b) you'll have to check what path is active on each motion event
c) the algorithm you can use to detect changes to the hover path, inside
the motion notification handler, where the GdkEventMotion is event, is:
GtkTreePath *hover_path;
GtkTreePath *last_hover_path;
/* last_hover_path = foo-stored_path; fetch last hover path */
gtk_tree_view_get_path_at_pos (GTK_TREE_VIEW (widget),
event-x, event-y,
hover_path,
NULL, NULL, NULL);
/* foo-stored_path = hover_path; write back new hover path */
if (!(last_hover_path == NULL hover_path == NULL)
(!(last_hover_path != NULL hover_path != NULL) ||
gtk_tree_path_compare (last_hover_path, hover_path) != NULL)) {
/* do whatever you want with the new hover path */
}

Children and precedence.
Is it possible to make a child window stay top level? I want the main window to be deactivated while certain child dialogs are open. I achieved this by using gtk_widget_set_sensitive(). Unfortunatly, If the user mistakenly clicks the screen out side of the dialog window, the parent window comes foreward covering the dialog. All input with this application will come from a touchscreen device... plus, I would not expect the user base to think of alt-tab .. also the program will run full screen without a window manager.. thus there will be no task bar unless I design one.
