range-reader

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.
