Arguments: list-view-item
This property has an effect only on the Windows platform, where it is provided by the underlying Microsoft control.
Returns the value of the checked property of a list-view-item
of a list-view control. The
value may be set at creation time by passing the :checked initarg to
make-instance, or any time
later by calling (setf
checked).
This property specifies whether a list-view-item
on a list-view
control is currently checked. This can
be true only if the show-check-boxes property of
the list-view
is true to
show the special column of check boxes. The default value
is nil
.
Typically an application would call checked on various list-view-item
s of a list-view
control once the user has exited the
dialog that contains the list-view
, to see which items the user has
checked. An application can also call (setf checked) on a list-view-item
to set whether that item is
checked or unchecked.
The generic function (setf checked) will also be called whenever
the end user interactively toggles the checked state of an item by
clicking on it. An application could add an :after method to catch
whenever the checked state changes, though it is more typical to give
the list-view
control an
on-check function, which will
be called when the state of any of its check boxes has changed.
