Arguments: list-view
This property has an effect only on the Windows platform, where it is provided by the underlying Microsoft control.
Returns the value of the on-check property of a list-view control. The value may be set at
creation time by passing the :on-check initarg to make-instance, or any time later by
calling (setf
on-check).
The value of this event-handler property should be a function or the
name of a function or nil. The default is
nil. When the value is a function or function
name and the show-check-boxes
property of the list-view
is true, then the function will be called whenever the state of one of
the list-view's check boxes has changed. This includes when the user
interactively toggles a check box by clicking on it, as well as when
the application programmatically changes the state of a check-box by
calling (setf
checked). The function should accept three arguments, which
will be the list-view widget, the list-view-item that was modified,
and t or nil to
indicate whether the item was checked or unchecked respectively.
