## data-object

Arguments: grid-row

Returns the arbitrary object from the application that is being represented by this grid-row. Typically, a data-object is assigned to a grid-row by passing the :data-object initarg to make-instance when creating the grid-row. draw-cell methods then often call data-object to retrieve values from the object to display in various cells.

For example, in the employee grid example the data-object of each grid-row is an instance of the "employee" class. These employee instances are completely independent of any user interface for them, and contain the real-world data for each employee. Whenever the grid wants to display some attribute of an employee in a grid-cell, it calls the grid-column's data-reader function on the grid-row's data-object to retrieve the needed real-world information from the employee object. The employee grid example can be found on the Examples tab of the Navigator.

data-object is a property of the `grid-row` and `column-header-row` classes.

See the `grid-widget` class for an overview of writing grid-widget code.
