gtk:popover-position (object)

object -- a gtk:popover widget
position -- a gtk:position-type value with the preferred popover position

Accessor of the position slot of the gtk:popover class. The gtk:popover-position function returns the preferred position of the popover. The (setf gtk:popover-position) function sets the preferred position for the popover to appear. If the popover is currently visible, it will be immediately updated.

This preference will be respected where possible, although on lack of space, for example, if close to the window edges, the gtk:popover widget may choose to appear on the opposite side.
