gtk:center-box-shrink-center-last (object)

object -- a gtk:center-box widget
setting -- a boolean whether to shrink the center widget after other children

The accessor for the shrink-center-last slot of the gtk:center-box class gets or sets whether to shrink the center widget after other children.

By default, when there is no space to give all three children their natural widths, the start and end widgets start shrinking and the center child keeps natural width until they reach minimum width. If set to false, start and end widgets keep natural width and the center widget starts shrinking instead.
