-Before we look at this program more closely, let me first expose its obvious flaws. The most obvious one is the awkward dialogue mechanism used to add and remove new products. A more appropriate thing to do would be to employ a context menu on which the addition and removal would be two separate choices. However, we have not yet introduced the context menu widget, and hence, instead used what you should already be familiar with. Also, we did not care to ensure the parent rows did not allow price column to be filled initially. And the most obvious flaw is that we do not provide a way to enter another top level product. All these issues can be easily fixed, however, the implementation of these fixes would greatly obscure the basic issues we are trying to present in the first place.

All these issues can be easily fixed, however, the implementation of these fixes would greatly obscure the basic issues we are trying to present in the first place. Nevertheless, the bare bones of this program have already been introduced two chapters back and pointed to at the beginning of this segment. If you gave trouble understanding how the program works I
suggest you have a peak back into the 'Using Tree Store' chapter as mentioned above (((<"Tedious Job of Loading Multidimensional Tree Store:"|tut-gtk2-treev-trees#Tedious Job of Loading Multidimensional Tree Store>))).
