The
:delete-item-callback
initarg of
capi:tree-view
is now documented, and its interface has changed.
In LispWorks 6.0 and earlier
delete-item-callback
makes multiple calls, one with each selected item. In LispWorks 6.1 and later it makes a single call with a list of the selected items. Existing programs that use
:delete-item-callback
in the subclass
capi:extended-selection-tree-view
need to be changed. The example in
examples/capi/choice/extended-selection-tree-view.lisp
shows a program that works both before and after this change.
