87 *
88 * Creates a new ECell renderer that can be used to render dates that
89 * that come from the model. The value returned from the model is
90 * interpreted as being a time_t.
91 *
92 * The ECellDate object support a large set of properties that can be
93 * configured through the Gtk argument system and allows the user to have
94 * a finer control of the way the string is displayed. The arguments supported
95 * allow the control of strikeout, bold, color and a date filter.
96 *
97 * The arguments "strikeout_column", "underline_column", "bold_column"
98 * and "color_column" set and return an integer that points to a
99 * column in the model that controls these settings. So controlling
100 * the way things are rendered is achieved by having special columns
101 * in the model that will be used to flag whether the date should be
102 * rendered with strikeout, underline, or bolded. In the case of the
103 * "color_column" argument, the column in the model is expected to
104 * have a string that can be parsed by gdk_color_parse().
105 *
106 * Returns: an ECell object that can be used to render dates.
