Recently,I am working on a configuration for an graphical application,which contains strings ,pixbuf(image).When I add double click function for the node ,it's can work.But the top node in response to "double click" too.How can I set the top node insensitive.See the function "void view_onRowActivated (GtkTreeView *treeview,GtkTreePath *path,GtkTreeViewColumn *col,gpointer userdata)" in the attachment.
