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.
