gtk:button-box-child-secondary (container child)

container -- a gtk:button-box widget
child -- a gtk:widget child widget
setting -- if true, the child widget appears in a secondary group of the button box

Accessor of the secondary child property of the button box. The gtk:button-box-child-secondary function returns whether the child widget should appear in a secondary group of children. The (setf gtk:button-box-child-secondary) function sets whether the child widget should appear in a secondary group of children. A typical use of a secondary child widget is the help button in a dialog.

This group appears after the other children if the style is the :start, :spread or :edge style, and before the other children if the style is the :end style. For horizontal button boxes, the definition of before/after depends on the direction of the widget, see the gtk:widget-direction function. If the style is the :start or :end style, then the secondary children are aligned at the other end of the button box from the main children. For the other styles, they appear immediately next to the main children.
