The gtk:button-box widget should be used to provide a consistent layout of buttons throughout your application. The layout/spacing can be altered by the programmer, or if desired, by the user to alter the 'feel' of a program to a small degree.

The gtk:button-box-layout-style function retrieves and alters the method used to spread the buttons in a button box across the container.

The main purpose of the gtk:button-box widget is to make sure the children have all the same size. The gtk:button-box widget gives all children the same size, but it does allow 'outliers' to keep their own larger size.

To excempt individual children from homogeneous sizing regardless of their 'outlier' status, you can set the non-homogeneous child property. The gtk:button-box widget uses a single CSS node with name buttonbox.
