## Implemented Interfaces

GtkButtonBox implements AtkImplementorIface, GtkBuildable and GtkOrientable.

## Includes

    #include <gtk/gtk.h>

## Description

The primary purpose of this class is to keep track of the various properties of GtkHButtonBox and GtkVButtonBox widgets.

`gtk_button_box_get_child_size()` retrieves the minimum width and height for widgets in a given button box.

The internal padding of buttons can be retrieved and changed per button box using `gtk_button_box_get_child_ipadding()` and `gtk_button_box_set_child_ipadding()` respectively.

`gtk_button_box_get_spacing()` and `gtk_button_box_set_spacing()` retrieve and change default number of pixels between buttons, respectively.

`gtk_button_box_get_layout()` and `gtk_button_box_set_layout()` retrieve and alter the method used to spread the buttons in a button box across the container, respectively.

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

Since 2.4

### gtk_button_box_set_spacing()

    #define gtk_button_box_set_spacing(b,s) gtk_box_set_spacing (GTK_BOX (b), s)

`gtk_button_box_set_spacing` is deprecated and should not be used in newly-written code.

Use `gtk_box_set_spacing()` instead.

Sets the amount of spacing between buttons in a given button box.

#### Parameters

b | a GtkButtonBox |
s | the number of pixels of spacing |

### gtk_button_box_set_layout ()

    void
    gtk_button_box_set_layout (GtkButtonBox *widget,

layout_style | the new layout style. |

### gtk_button_box_set_child_size ()

    void
    gtk_button_box_set_child_size (GtkButtonBox *widget,
                                   gint min_width,
                                   gint min_height);

`gtk_button_box_set_child_size` is deprecated and should not be used in newly-written code.

This is not supported anymore and can only be set through the theme changing the style properties: "child-min-width" and "child-min-height" instead.

Sets a new default size for the children of a given button box.

#### Parameters

widget | a GtkButtonBox |
min_width | a default width for buttons in `widget` |
min_height | a default height for buttons in `widget` |

### gtk_button_box_set_child_ipadding ()

    void
    gtk_button_box_set_child_ipadding (GtkButtonBox *widget,
                                       gint ipad_x,

ipad_y | the vertical padding that should be used by each button in `widget` . |

### gtk_button_box_set_child_secondary ()

    void
    gtk_button_box_set_child_secondary (GtkButtonBox *widget,
                                        GtkWidget *child,
                                        gboolean 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 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.

#### Parameters

widget | a GtkButtonBox |
child | a child of `widget` |
is_secondary | if `TRUE`, the `child` appears in a secondary group of the button box. |
