| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: object-editor
Returns a list of the particular instances that an object-editor
dialog is editing, or
nil
if the object-editor
is editing all instances of a
persistent class. The value may be set with the
edited-instances initarg at creation time, or any
time later by calling (setf edited-instances). The default
value is nil
. If this property is never set,
then the dialog will attempt to edit all instances of its edited-class, though this requires
that the class be a persistent (AllegroCache) class so that all
instances can be found.
At this time, editing a huge number of instances may be unwieldy
because an object-editor
always sorts the instances (typically according to the primary-name-slot of the class if
any), which entails loading every instance from a database (if the
instances are coming from a database). This is done to facilitate
browsing the instances in an intuitive order, and for the object-editor-select facility to be
able to present many instances as a series of alphabetized pop-up
menus. And the object-editor-search facility needs to load
every instance in order to search one or more of its slots. Options
may be added in the future to facilitate handling large databases
better.
For the related class-grid
widget, the value property is
used instead of an edited-instances property to store the list of
instances, and a value of nil
will display no
instances rather than all of them.
