-Now it is time to augment our Grocery List application. The only difference in main body of the this application in comparison to the program from the earlier session is the addition of Gtk::Stock::ADD and Gtk::Stock::REMOVE buttons. Also the selection mode is changed to Gtk::SELECTION_MULTIPLE to allow users to select multiple rows at the time. The core change and the major additions to the application are in the methods called ((*add_product*)) and ((*remove_products.*)) If user clicks the "+Add" button the application presents a Gtk::Dialog that asks the user to choose a category, enter a product name and quantity of products to buy, and to select whether or not to purchase the product.

+There is a hidden and with regards to selections irrelevant feature added, namely the((*tooltip*)). If user hovers the cursor over the tree view display or over the remove button two different tool-tip messages are displayed to the user.
