Description The primary purpose of this class is to keep track of the various properties of GtkHButtonBox and GtkVButtonBox widgets. gtk_button_box_get_child_size() retrieves the minimum width and height for widgets in a given button box. 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. gtk_button_box_get_spacing() and gtk_button_box_set_spacing() retrieve and change default number of pixels between buttons, respectively. gtk_button_box_get_layout() and gtk_button_box_set_layout() retrieve and alter the method used to spread the buttons in a button box across the container, respectively. The main purpose of GtkButtonBox is to make sure the children have all the same size. Therefore it ignores the homogeneous property which it inherited from GtkBox, and always behaves as if homogeneous was TRUE.
