== Not a button but vaguely related Button Box
As the title above suggests this widget does not really belong between the buttons, however there are a few features included with it that prompted its inclusion in this batch of sessions dealing with buttons.
Gtk::Bin
| Gtk::Window
| | Gtk::Button
| | | Gtk::ToggleButton
| | | | Gtk::CheckButton
| | | | | Gtk::RadioButton
| | | Gtk::ColorButton
| | | Gtk::FontButton
| | | Gtk::LinkButton
| | | Gtk::OptionMenu
| | | Gtk::ScaleButton
| | | | Gtk::VolumeButton
Gtk::Box
| Gtk::ButtonBox
| | Gtk::HButtonBox
| | Gtk::HButtonBox
The above hierarchy clearly shows two distinct hierarchies. What makes the two related is the fact that these boxes are used to pack buttons. The primary purpose of Gtk::ButtonBox class is to keep track of the various properties of Gtk::HButtonBox and Gtk::VButtonBox widgets.
Once a button box is created with either Gtk::HButtonBox.new or Gtk::HButtonBox.new, you may be required to set up the layout style for the buttons within the box. You accomplish this with the following methods:
* Gtk::ButtonBox#layout_style - Retrieves the method being used to arrange the buttons in a button box.
* Gtk::ButtonBox#layout_style=(style) - Changes the way buttons are arranged in their container.
* Gtk::ButtonBox#set_layout_style(style) - Same as Gtk::ButtonBox#layout_style=.
In the above method calls the style argument will be one of the following:
--- Gtk::ButtonBox Style
Used to dictate the style that a Gtk::ButtonBox uses to layout the buttons it contains.
* DEFAULT_STYLE - Default packing.
* SPREAD - Buttons are evenly spread across the Gtk::ButtonBox.
* EDGE - Buttons are placed at the edges of the Gtk::ButtonBox.
* START - Buttons are grouped towards the start of box, (on the left for a Gtk::HBox, or the top for a Gtk::VBox).
* END - Buttons are grouped towards the end of a box, (on the right for a Gtk::HBox, or the bottom for a Gtk::VBox).
* CENTER
Finally you have add buttons with Gtk::ButtonBox#add_child (See Gtk::Buildable#add_child).
