on-sort-predicate

Generic Function

Package: common-graphics

Arguments: standard-object

Returns or sets with setf the value of the on-sort-predicate event property of the argument. The value should be a function object or a function name (a symbol naming a function). The value should not be nil.

The function is used to sort the elements of the argument, which is an object with sortable elements like a list-view-column. The initial value is string< which sorts in alphabetical order. If another function is specified, it must accept two arguments and return true when the first argument should precede the second in the listing.
