Arguments: grid-column
Returns (or sets with setf) a function to return the list of values
for a cell that is in a combo-box-column-mixin
grid-column. This function should
accept one argument, which is the data-object of a grid-row. A range-reader may also be
nil rather than a function, in which case no
choices are displayed by the combo-box. The default value is nil.
For example, if the grid column that a range-reader is on is displaying the department of each employee that is displayed in a grid row, then the range-reader function might take an employee as its argument and return a list of the departments into which that employee could be moved. The employee grid example can be found on the Examples tab of the Navigator.
See the grid-widget class
for an overview of writing grid-widget code.
