## show-check-boxes

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.
