gtk:box-baseline-position (object)

object -- a gtk:box container widget
position -- a gtk:baseline-position value for the baseline position

The accessor for the baseline-position slot gets or sets the baseline position of a box. This affects only horizontal boxes with at least one baseline aligned child widget. If there is more vertical space available than requested, and the baseline is not allocated by the parent widget then position is used to allocate the baseline with respect to the extra space available.
