GtkVButtonBox a container for arranging buttons vertically. A button box should be used to provide a consistent layout of buttons throughout your application. There is one default layout and a default spacing value that are persistant across all #VButtonBox widgets. The layout/spacing can then be altered by the programmer, or if desired, by the user to alter the 'feel' of a program to a small degree. A #VButtonBox is created with gtk_vbutton_box_new(). Buttons are packed into a button box the same way as any other box, using gtk_box_pack_start() or gtk_box_pack_end(). The default spacing between buttons can be set with gtk_vbutton_box_set_spacing_default() and queried with gtk_vbutton_box_get_spacing_default(). The arrangement and layout of the buttons can be changed using gtk_vbutton_box_set_layout_default() and queried with gtk_vbutton_box_get_layout_default(). #GtkBox Used to pack widgets into button boxes. #GtkButtonBox Provides functions for controlling button boxes. #GtkHButtonBox Pack buttons horizontally.
