# Detail

The primary purpose of this class is to keep track of the various properties of `HButtonBox` and `VButtonBox` widgets.

`buttonBoxGetChildSize` retrieves the minimum width and height for widgets in a given button box. `buttonBoxSetChildSize` allows those properties to be changed.

The internal padding of buttons can be retrieved and changed per button box using `buttonBoxGetChildIpadding` and `buttonBoxSetChildIpadding` respectively.

`buttonBoxGetSpacing` and `buttonBoxSetSpacing` retrieve and change default number of pixels between buttons, respectively.

`buttonBoxGetLayout` and `buttonBoxSetLayout` retrieve and alter the method used to spread the buttons in a button box across the container, respectively.

The main purpose of `ButtonBox` is to make sure the children have all the same size. Therefore it ignores the homogeneous property which it inherited from `Box`, and always behaves as if homogeneous was `True`.

# Methods

buttonBoxGetLayout :: ButtonBoxClass self => self -> IO ButtonBoxStyle

Retrieves the method being used to arrange the buttons in the button box.

buttonBoxSetLayout

Arguments

:: ButtonBoxClass self |
=> self |
-> ButtonBoxStyle | `layoutStyle` - the new layout style.
-> IO () |

Changes the way buttons are arranged in their container.

buttonBoxSetChildSecondary

Arguments

:: (ButtonBoxClass self, WidgetClass child) |
=> self |
-> child | `child` - a child of the button box widget
-> Bool | `isSecondary` - if `True`, the `child` appears in a secondary group of the button box.
-> IO () |

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 `ButtonboxStart`, `ButtonboxSpread` or `ButtonboxEdge`, and before the other children if the style is `ButtonboxEnd`. For horizontal button boxes, the definition of before/after depends on direction of the widget (see `widgetSetDirection`). If the style is `ButtonboxStart` or `ButtonboxEnd`, 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.

buttonBoxGetChildSecondary

Arguments

:: (ButtonBoxClass self, WidgetClass child) |
=> self |
-> child | `child` - a child of the button box widget
-> IO Bool | returns whether `child` should appear in a secondary group of children.

Returns whether `child` should appear in a secondary group of children.

- Available since Gtk+ version 2.4

# Attributes

buttonBoxLayoutStyle :: ButtonBoxClass self => Attr self ButtonBoxStyle

How to layout the buttons in the box. Possible values are default, spread, edge, start and end.

Default value: `ButtonboxDefaultStyle`

# Child Attributes

buttonBoxChildSecondary :: (ButtonBoxClass self, WidgetClass child) => child -> Attr self Bool

If `True`, the child appears in a secondary group of children, suitable for, e.g., help buttons.

Default value: `False`
