= class Gtk::ButtonBox
The primary purpose of this class is to keep track of the various properties of Gtk::HButtonBox and Gtk::VButtonBox widgets.
== super class
* Gtk::Box
== public instance methods
--- layout_style
Retrieves the method being used to arrange the buttons in a button box.
* Returns: GtkButtonBoxStyle. the method used to layout buttons in widget.
--- layout_style=(style)
Changes the way buttons are arranged in their container.
* style: GtkButtonBoxStyle. the new layout style.
* Returns: style
--- set_layout_style(style)
Same as layout_style=.
* layout_style : the new layout style.
* Returns: self
--- set_child_secondary(child, is_secondary)
Sets whether child should appear in a secondary group of children. A typical use of a secondary child is the help button in a dialog.
This group appears after the other children if the style is Gtk::ButtonBox::START, Gtk::ButtonBox::SPREAD or Gtk::ButtonBox::EDGE, and before the the other children if the style is Gtk::ButtonBox::END.
For horizontal button boxes, the definition of before/after depends on direction of the widget (see Gtk::Widget::set_direction). If the style is Gtk::ButtonBox::START or Gtk::ButtonBox::END, 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.
*child: a child of widget
*is_secondary : if true, the child appears in a secondary group of the button box.
