auto-arrange

Arguments: list-view

A boolean value indicating whether a list-view control will automatically arrange its list-view-items back into a rectangular array whenever an item is moved or the list-view is resized. This is done only when the layout-style of the list-view is either :small-icon or :large-icon. If nil (the default), then no automatic arrangement is done. If t, then automatic arrangement is done. The arrangement is done when setting this property to t as well.

For example, if the attachment properties (top-attachment, etc.) of a list-view control are set up so that the list-view is resized whenever the end user resizes its parent dialog, then the icons will be re-arranged to fill the new size of the list-view control if auto-arrange has been turned on.

A current incapacity of the list-view control is that it is not allowing the end user to drag list-view-items to new arbitrary positions, as it should when the layout-style is either :small-icon or :large-icon. But if a list-view-item is moved programmatically by calling (setf list-view-item-position), then auto-arrangement will still occur, and place the item back into the rectangular array position that is closest to the position to which the list-view-item was moved.
