arrange-icons

Arguments: list-view &key align

This function moves the icons in a list-view control if needed so that they are aligned horizontally and vertically and spaced equally. This is done only if the current layout-style is either :large-icon or :small-icon, since otherwise the items always appear as a single vertical list. The items will be arranged according to the value of the alignment property of the list-view.

align determines the value of the alignment property that is in effect when the arrangement is done. If either :left or :top, then the alignment property is first set to this value, and the arrangement is then done using that alignment value. If nil, then the current type of alignment is used.

This function will probably be needed only if the list-view is resized and its auto-arrange property is false, or if the function (setf list-view-item-position) has been used on some of the list-view's items.

See list-view.
