-Finally, lets also address the two issues, mentioned in two places first when introducing the first version of 'treev-MultiDim-load-asci-table.rb' program example under the title ((<"Tedious Job of Loading Multidimensional Tree Store:"|tut-gtk2-treev-trees#Tedious Job of Loading Multidimensional Tree Store>)), where we were concerned by adding and removing rows from a multi-level tree view and tree store, and second the 'imaginary root node' issue in the segment called '((<"Imaginary, invisible root node"|tut-gtk2-treev-rr#Imaginary, invisible root node:>))'.
+Finally, lets also address the two issues, mentioned earlier. The first when introducing the first version of the 'treev-MultiDim-load-asci-table.rb' program example under the title ((<"Tedious Job of Loading Multidimensional Tree Store:"|tut-gtk2-treev-trees#Tedious Job of Loading Multidimensional Tree Store>)), where we were concerned about adding and removing rows from a multi-level tree view and tree store, and the second about the 'imaginary root node' issue which we encountered in the segment called '((<"Imaginary, invisible root node"|tut-gtk2-treev-rr#Imaginary, invisible root node:>))'.
The last, 'imaginary root node issue' we have also seen in the above (adding-n-removing-rows.rb) example program, though we did not really expose it. But it will be more obvious in the next example. As promised this last example is an extension of the 'treev-MultiDim-load-asci-table.rb' program in which we loaded the tree model and view, from the asci table residing in a separate file as a module. We are going to use the same module file here too. What is new is the feature that allows us to add and remove rows. This time however, we use a different row selection mechanism than in the above (adding-n-removing-rows.rb) example program. In both cases, when we insert a row or delete it we point to it by clicking on it. When adding a row we are adding a single child to an existing parent row. When removing a row, we are removing the selected row and all its children if they exist.
