gtk-box-child-fill (container child)

container -- a gtk-box container widget
child -- the gtk-widget child widget
fill -- true, if space given to child by the expand option

Accessor of the fill child property of the gtk-box class.

Whether the child widget should fill extra space or use it as padding. The halign or valign properties are the preferred way to influence whether the child widget fills available space, by setting the align property of the child widget corresponding to the orientation of the box to the :fill value of the gtk-align enumeration to fill, or to something else to refrain from filling.
