Set up a foreach scenario for all selected items:

	GtkTreeSelection *selection = NULL;

	selection = gtk_tree_view_get_selection(view);
	gtk_tree_selection_foreach(selection, remove_cb, NULL);

then in the callback:

	void remove_cb(GtkTreeModel *model, GtkTreePath *path,
GtkTreeIter *iter, gpointer userdata)
	{
		GtkTreeStore *store = NULL;

		store = GTK_TREE_STORE(model);
		gtk_tree_store_remove(store, iter);
	}


Regards,
Martyn
