It determines the geometry, type. As mentioned earlier, a tree view displays one or more Gtk::TreeViewColumn objects. Tree columns are composed of a header and the cells of data that are organized as one column. Each tree view column can contain one or more visible columns of data. For instance, in a file browser, a tree view column may contain one column of "icon file images" and one column of "file names". The header of the Gtk::TreeViewColumn object contains a title that describes what data is held in the cells below. If you make the column sortable, the rows will be sorted when a sortable column header is clicked. Gtk::TreeViewColumn objects actually do not render anything to the screen. This is done with an object derived from the Gtk::CellRenderer.
