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 show-check-boxes property of
a list-view
control. The
value may be set at creation time by passing the :show-check-boxes
initarg to make-instance, or
any time later by calling (setf show-check-boxes).
This property specifies whether a list-view
has a special column of check boxes on
the left side of the control. When the user clicks a check box in this
column to toggle its state, the (setf checked) generic function will be
called, which will call the list-view-item
's on-check function if it has one. An
application may also call (setf checked) programmatically to change
the state of the check boxes.
The value can be nil
or true. The default is
nil
.
show-check-boxes should not be used along with a state-image-list, because it is implemented as a special type of state image list.
