25     This demo shows a table with key/value pairs. The values can be edited.
26     There are two types of values: strings and bools. Dependent of the type,
27     either a CellRendererText or CellRendererToggle is used to show and edit
28     the value.
29 
30     This is done by connecting the visibility of a CellRenderer to a
31     ListStore column.
32 
33     2018-03-29: ref to issiue #231
34     Added colors in first column GdkColor & RGBA.
35     This tests ListStore storing more complex attribute, than simple GType.
