gtk:center-box-baseline-position (object)

object -- a gtk:center-box widget
position -- a value of the gtk:baseline-position enumeration

The accessor for the baseline-position slot of the gtk:center-box class gets or sets the position of the baseline aligned widgets if extra space is available.

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 the position value is used to allocate the baseline with respect to the extra space available.
