==== Cell Renderers:
-As we have seen, after creating the Gtk::TreeView, you have to add one or more columns to the view for it to be of any use. Each Gtk::TreeViewColumn is composed of a header displaying a short description of its content, and at least one cell renderer. All cell renderers are derived from the Gtk::CellRenderer class. Each cell renderer contains a number of properties that determine how data will be drawn within a cell.
-The Gtk::CellRenderer class provides common properties to all derived renderer classes including: background colour, size parameters, alignment, mode, visibility, sensitivity, padding, etc. You should check the API documentation for full list. It also provides ((*editing_canceled*)) and ((*editing-started*)) signals, the former emitted when the user cancels the process of editing a cell, and the latter emitted when a cell is started to be edited.
