gtk:popover-constrain-to (object)

object -- a gtk:popover widget
constraint -- a value of the gtk:popover-constraint enumeration

Accessor of the constrain-to slot of the gtk:popover class. The gtk:popover-constrain-to function returns the constraint for placing this popover. The (setf gtk:popover-constrain-to) function sets a constraint for positioning this popover.

Note that not all platforms support placing popovers freely, and may already impose constraints.
