Displaying Boolean values as "TRUE" or "FALSE" with Gtk::CellRendererText, especially in large tables with many Boolean columns, becomes soon very illegible and aesthetic, as well as it also takes up a too much valuable visible area. You would significantly improve lucidity of your Boolean tables if instead of text strings you displayed a check button for Boolean values. As it turns out you can do just that, with the help of the toggle button cell renderers called Gtk::CellRendererToggle. By default, they are drawn as check buttons, but can also be set up as radio buttons, however, that would also require you yourself implement the necessary radio button functionality.
-As with the editable text renderers, you have to manually apply the changes performed by the user. Otherwise, the button will not toggle visually on the screen. Because of this, Gtk::CellRendererToggle provides the((*toggle*))signal, which is emitted when the user presses the check button.
