Arguments: outline
Returns (or sets with setf) the value of this property of outline. This property determines whether all descendent outline-items of an outline-item that is being closed are also closed.
When true, closing and then re-opening an outline-item results in the item's subitems reappearing without any of their subitems reappearing, even if they were visible before closing the outline-item. When false, closing and reopening an outline-item results in the tree of subitems reappearing just as it was before the outline-item was closed. (The Windows File Explorer works as if this property were false. Suppose some folders in the C drive have subfolders that are displayed. Clicking on the boxed - next to the C drive icon renders all folders in C invisible but when you then click on the boxed + next to the C drive icon, the folders reappear and those folders that were open before are open again.)
The value of this property defaults to t for backward compatibility,
but may be set to nil
to achieve behavior
similar to the Windows File Explorer.
close-subtrees-on-close is a
property of the outline
class.
