## Description

GooCanvasGroupModel 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.

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

GooCanvasGroupModel implements the GooCanvasItemModel interface, so you can use the GooCanvasItemModel functions such as `goo_canvas_item_model_raise()` and `goo_canvas_item_model_rotate()`, and the properties such as "visibility" and "pointer-events".

To create a GooCanvasGroupModel use `goo_canvas_group_model_new()`.

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

To respond to events such as mouse clicks on the group you must connect to the signal handlers of the corresponding GooCanvasGroup objects. (See `goo_canvas_get_item()` and "item-created".)

## Details

### struct GooCanvasGroupModel

    struct GooCanvasGroupModel;

The GooCanvasGroupModel struct contains private data only.

### goo_canvas_group_model_new ()

    GooCanvasItemModel * goo_canvas_group_model_new         (GooCanvasItemModel *parent,
                                                             ...);

Creates a new group item.

`parent` : | the parent model, 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 model. [transfer full]
