== Adding Rows and Handling Selections
-All of the examples that we have encountered so far in the "Tree View Widget" tutorial session, load the data into the tree model during the start-up. However, it is also possible to load data interactively. Here we will first expand the((*Grocery List*))application to allow users to add and remove products, and then investigate a more elaborate tree view application of products, we also have already seen in the 'Using Gtk::TreeStore' chapter where we were looking at different ways to load ascii data (arrays) into tree store in the segment entitled '((<"Tedious Job of Loading Multidimensional Tree Store"|tut-gtk2-treev-trees#Tedious Job of Loading Multidimensional Tree Store>))'. In this later expanded (treev-MultiDim-loadASCI-add-n-rm-rows.rb) example we will deal particularly with the issue of child hierarchies that rows in a tree view may have and which too are affected when adding new or removing existing rows. However, before we dive into the((*adding-n-removing-rows.r
b*))example, we will learn how to handle single and multiple selections.
