center-modal-children

Arguments: window

Called by the default position-utility-dialog method to decide which convention to use for positioning a utility dialog. The default method simply returns the value of the center-all-modal-dialogs-on-screen configuration option, which is either nil, t, or :on-owner. An application could add methods on this generic function to override the global configuration default for particular owner windows. The method should still return one of the three possible values of center-all-modal-dialogs-on-screen if the default position-utility-dialog method is used.
