Arguments: basic-pane
This function returns the owner of the argument if there is one. If the argument is a child window or a non-owned top-level window, this function returns its parent (which is a window for a child window or the screen for a non-owned top-level window).
Release 6.0 incompatibility note: in releases prior to 6.0,
nil (instead of the parent) was returned when
the argument was a child window or a non-owned top-level window. This
change allows getting rid of the redundant function parent-or-owner, leaving only the
functions parent
and owner. It
also brings owner
into line with the meaning of the term
"owner", which is "the window with which a specified window shrinks
and closes", since the parent of a child window has that behavior in
addition to the other parent behaviors.
Applications developed in release prior to 6.0 that call owner will probably typically be able to leaves the calls as they are. But if an application depends on owner to return nil for a child window, then it should substitute a form such as
(and (not (child-p window)) (owner window))
for the call to owner. And if an application depends on owner to return nil for a non-owned top-level window, then it should substitute a form such as
(and (windowp (owner window))(owner window))
Note that a so-called "non-owned top-level window" is now one whose owner is the screen rather than a window.
