allows those properties to be changed.
</para>
<para>
The internal padding of buttons can be retrieved and changed per button box using
gtk_button_box_get_child_ipadding() and gtk_button_box_set_child_ipadding()
respectively.
</para>
<para>
gtk_button_box_get_spacing() and gtk_button_box_set_spacing() retrieve and
change default number of pixels between buttons, respectively.
</para>
<para>
