|
|
* @short_description: A Generic layout container
|
|
*
|
|
* #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 #ClutterActor: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().
|
|
*
|
|
* |[<!-- language="C" -->
|
|
* 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.
