## on-sort-key

Arguments: list-view-column

Returns or sets with setf the value of the on-sort-key event property of list-view-column. See `list-view` and `list-view-column`.

The value should be a function object or a function name (a symbol naming a function), or `nil`. The function should accept one argument and is applied to each object in list-view-column to be sorted to produce the actual value on which sorting is based. See the key argument to sort. If the value is `nil`, the objects themselves are sorted.

See cg-events.htm for information about event handling in Common Graphics.
