## Description

A button box is used to provide a consistent layout of buttons throughout an application. The `gtk.ButtonBox` is subclassed by the `gtk.HButtonBox` and `gtk.VButtonBox` classes to provide horizontal and vertical button layouts respectively. The same effect could be achieved by using a `gtk.Box` but less conveniently.

A buttonbox provides one default layout and a default spacing value that are persistent across all 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.

The `gtk.Box.get_spacing`() method and the `gtk.Box.set_spacing`() methods retrieve and change the default number of pixels between buttons. The `get_layout`() and `set_layout`() methods retrieve and alter the style used to spread the buttons in a button box across the container. The layout styles are: `gtk.BUTTONBOX_SPREAD`, `gtk.BUTTONBOX_EDGE`, `gtk.BUTTONBOX_START` and `gtk.BUTTONBOX_END`.

## Methods

### gtk.ButtonBox.get_layout

        def get_layout()

Returns : | the layout style used by the buttonbox

The `get_layout`() method returns the current value of the "layout-style" property. The possible values are: `gtk.BUTTONBOX_SPREAD`, `gtk.BUTTONBOX_EDGE`, `gtk.BUTTONBOX_START` and `gtk.BUTTONBOX_END`.

### gtk.ButtonBox.set_layout

        def set_layout(layout_style)

`layout_style` : | the new layout style

The `set_layout`() method sets the "layout-style" property to the value in `layout_style`. The possible values are: `gtk.BUTTONBOX_SPREAD`, `gtk.BUTTONBOX_EDGE`, `gtk.BUTTONBOX_START` and `gtk.BUTTONBOX_END`.

### gtk.ButtonBox.get_child_secondary

        def get_child_secondary(child)

`child` : | a child button of the buttonbox
Returns : | if `True`, the `child` appears in a secondary group of the button box.

### Note

This method is available in PyGTK 2.4 and above.

The `get_child_secondary`() method returns `True` if `child` should appear in a secondary group of children. See the `set_child_secondary`() method for more information.

### gtk.ButtonBox.set_child_secondary

        def set_child_secondary(child, is_secondary)

`child` : | a child button of the buttonbox
`is_secondary` : | if `True`, the `child` appears in a secondary group of the button box.

The `set_child_secondary`() method sets whether `child` should appear in a secondary group of children. The typical use of a secondary child is the help button in a dialog that is displayed away from the main group of buttons e.g. right aligned.

The secondary 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.
