We save the "path" of the iterator that points to the parent (our product category), and create a new row for our new product. Adding the data to the new empty row is accomplished by:
- # child[$buy_it]=buy # same as: model.set_value(child, $buy_it, buy)
- child[$buy_it] = buy
- child[$quantity] = quantity
- child[$product] = product
+ # child[BUY_INDEX]=buy # same as: model.set_value(child, BUY_INDEX, buy)
+ child[BUY_INDEX] = buy
+ child[QTY_INDEX] = quantity
+ child[PROD_INDEX] = product
It is worth noticing the comment here which tells us that the Gtk::TreeIter#[column] and Gtk::TreeModel#set_value instance methods can be used interchangeably.
