gtk:popover-relative-to (object)

object -- a gtk:popover widget
relative-to -- a gtk:widget object

Accessor of the relative-to slot of the gtk:popover class. The gtk:popover-relative-to function returns the widget the popover is currently attached to. The (setf gtk:popover-relative-to) function sets a new widget to be attached to the popover. If the popover is visible, the position will be updated. The ownership of popovers is always given to their relative-to widget, so if the relative-to argument is set to nil on an attached popover, it will be detached from its previous widget, and consequently destroyed unless extra references are kept.
