## Implemented Interfaces

GooCanvasGroup implements GooCanvasItem.

## Description

GooCanvasGroup represents a group of items. Groups can be nested to any depth, to create a hierarchy of items. Items are ordered within each group, with later items being displayed above earlier items.

GooCanvasGroup is a subclass of GooCanvasItemSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width". Setting a style property on a GooCanvasGroup will affect all children of the GooCanvasGroup (unless the children override the property setting).

GooCanvasGroup implements the GooCanvasItem interface, so you can use the GooCanvasItem functions such as `goo_canvas_item_raise()` and `goo_canvas_item_rotate()`, and the properties such as "visibility" and "pointer-events".

If the “width” and “height” properties are set to positive values then the group is clipped to the given size.

To create a GooCanvasGroup use `goo_canvas_group_new()`.

To get or set the properties of an existing GooCanvasGroup, use `g_object_get()` and `g_object_set()`.

## Functions

### goo_canvas_group_new ()

    GooCanvasItem *
    goo_canvas_group_new (GooCanvasItem *parent,
                          ...);

Creates a new group item.

#### Parameters

parent | the parent item, or `NULL`. If a parent is specified, it will assume ownership of the item, and the item will automatically be freed when it is removed from the parent. Otherwise call `g_object_unref()` to free it. | [skip]
... | optional pairs of property names and values, and a terminating `NULL`. |

#### Returns

a new group item.
