## Implemented Interfaces

ClutterBox implements ClutterContainer, ClutterScriptable, ClutterAnimatable and AtkImplementorIface.

## Description

ClutterBox is a ClutterActor sub-class implementing the ClutterContainer interface. A Box delegates the whole size requisition and size allocation to a ClutterLayoutManager instance.

ClutterBox is available since Clutter 1.2

ClutterBox is deprecated since Clutter 1.10; all its relevant API is provided by ClutterActor, via the “layout-manager” property.

#### Using ClutterBox

The following code shows how to create a ClutterBox with a ClutterLayoutManager sub-class, and how to add children to it via `clutter_box_pack()`.

    ClutterActor *box;
    ClutterLayoutManager *layout;

    // Create the layout manager first
    layout = clutter_box_layout_new ();
    clutter_box_layout_set_homogeneous (CLUTTER_BOX_LAYOUT (layout), TRUE);
    clutter_box_layout_set_spacing (CLUTTER_BOX_LAYOUT (layout), 12);

    // Then create the ClutterBox actor. The Box will take
    // ownership of the ClutterLayoutManager instance by sinking
    // its floating reference
    box = clutter_box_new (layout);

    // Now add children to the Box using the variadic arguments
    // function clutter_box_pack() to set layout properties
    clutter_box_pack (CLUTTER_BOX (box), actor,
                      "x-align", CLUTTER_BOX_ALIGNMENT_CENTER,
                      "y-align", CLUTTER_BOX_ALIGNMENT_END,
                      "expand", TRUE,
                      NULL);

ClutterBox's `clutter_box_pack()` wraps the generic `clutter_container_add_actor()` function, but it also allows setting layout properties while adding the new child to the box.

## Functions

### clutter_box_new ()

    ClutterActor *
    clutter_box_new (ClutterLayoutManager *manager);

`clutter_box_new` has been deprecated since version 1.10 and should not be used in newly-written code.

Use `clutter_actor_new()` instead.

Creates a new ClutterBox. The children of the box will be layed out by the passed `manager`

#### Parameters

manager | a ClutterLayoutManager |

#### Returns

the newly created ClutterBox actor

Since 1.2

### clutter_box_set_layout_manager ()

    void
    clutter_box_set_layout_manager (ClutterBox *box,
                                    ClutterLayoutManager *manager);

`clutter_box_set_layout_manager` has been deprecated since version 1.10 and should not be used in newly-written code.

Use `clutter_actor_set_layout_manager()` instead.

Sets the ClutterLayoutManager for `box`

A ClutterLayoutManager is a delegate object that controls the layout of the children of `box`

#### Parameters

box | a ClutterBox |
manager | a ClutterLayoutManager |

Since 1.2

### clutter_box_get_layout_manager ()

    ClutterLayoutManager *
    clutter_box_get_layout_manager (ClutterBox *box);

`clutter_box_get_layout_manager` has been deprecated since version 1.10 and should not be used in newly-written code.

Use `clutter_actor_get_layout_manager()` instead.

Retrieves the ClutterLayoutManager instance used by `box`

#### Parameters

box | a ClutterBox |

#### Returns

a ClutterLayoutManager. The returned ClutterLayoutManager is owned by the ClutterBox and it should not be unreferenced.

[transfer none]

Since 1.2

### clutter_box_set_color ()

    void
    clutter_box_set_color (ClutterBox *box,
                           const ClutterColor *color);

`clutter_box_set_color` has been deprecated since version 1.10 and should not be used in newly-written code.

Use `clutter_actor_set_background_color()` instead.

Sets (or unsets) the background color for `box`

#### Parameters

box | a ClutterBox |
color | the background color, or `NULL` to unset. | [allow-none]

Since 1.2

### clutter_box_get_color ()

    void
    clutter_box_get_color (ClutterBox *box,
                           ClutterColor *color);

`clutter_box_get_color` has been deprecated since version 1.10 and should not be used in newly-written code.

Use `clutter_actor_get_background_color()` instead.

Retrieves the background color of `box`

If the “color-set” property is set to `FALSE` the returned ClutterColor is undefined

#### Parameters

box | a ClutterBox |
color | return location for a ClutterColor. | [out caller-allocates]

Since 1.2

### clutter_box_pack ()

    void
    clutter_box_pack (ClutterBox *box,

                      ...);

`clutter_box_pack` has been deprecated since version 1.10 and should not be used in newly-written code.

Use `clutter_actor_add_child()` instead. To set specific layout properties, use `clutter_layout_manager_child_set()`

This function is a wrapper around `clutter_container_add_actor()` and `clutter_layout_manager_child_set()`

Language bindings should use the vector-based `clutter_box_packv()` variant instead

#### Parameters

box | a ClutterBox |
actor | a ClutterActor |
first_property | the name of the first property to set, or `NULL` |
... | a list of property name and value pairs, terminated by `NULL` |

                       const gchar * const properties[],
                       const GValue *values);

`clutter_box_packv` has been deprecated since version 1.10 and should not be used in newly-written code.

Use `clutter_actor_add_child()` instead. To set specific layout properties, use `clutter_layout_manager_child_set()`
