There are three ways to deal with tree view selections: either you get a list of the currently selected rows whenever you need it, for example within a context menu method, or you keep track of all select and unselect actions and keep a list of the currently selected rows around for whenever you need them; as a last resort, you can also traverse your list or tree and check each single row for whether it is selected or not (which you need to do if you want all rows that are not selected for example).

== Checking Whether a Row is Selected
-You can check whether a given row is selected or not using the Gtk::TreeSelection#iter_is_selected? and Gtk::TreeSelection#path_is_selected? methods. If you want to know all rows that are ((*not*)) selected, for example, you could just traverse the whole list or tree, and use the above methods to check for each row whether it is selected or not (See the code entitled "Example obtaining only NON-selected rows" above).
