Signature

remove-items collection list-or-predicate

Arguments

Description

The generic function remove-items removes from the collection collection those items determined by list-or-predicate.

If list-or-predicate is list, then the items removed are those matching some element of list-or-predicate, compared by the test-function of collection. Otherwise, the items removed are those for which the function list-or-predicate returns true.

This is logically equivalent to recalculating the collection items and then calling (setf collection-items). However, remove-items is more efficient and causes less flickering on screen.

remove-items can only be used when the collection has the default items-get-function svref.

Notes

remove-items cannot be used a graph-pane or a tree-view.
