gtk:popover-offset (popover)

popover -- a gtk:popover widget
xoffset -- an integer with the xoffset
yoffset -- an integer with the yoffset

The gtk:popover-offset function gets the offset to use when calculating the position of the popover. The (setf gtk:popover-offset) function sets the offset. These values are used when preparing the gdk:popup-layout object for positioning the popover.
