## Implemented Interfaces

GooCanvasItemModelSimple implements GooCanvasItemModel.

## Description

GooCanvasItemModelSimple is used as a base class for the standard canvas item models. It can also be used as the base class for new custom canvas item models.

The Model/View canvas feature may be removed in a future version of GooCanvas.

It provides default implementations for many of the GooCanvasItemModel methods.

Subclasses of GooCanvasItemModelSimple only need to implement the `create_item()` method of the GooCanvasItemModel interface, to create the default canvas item to view the item model.

## Functions

## Types and Values

### struct GooCanvasItemModelSimple

    struct GooCanvasItemModelSimple {
      GooCanvasItemModel *parent;
      GooCanvasItemSimpleData simple_data;
    };

The GooCanvasItemModelSimple struct contains the basic data needed to implement canvas item models.

#### Members

GooCanvasItemModel *`parent`; | the parent model. |
GooCanvasItemSimpleData `simple_data`; | data used by the canvas item for viewing the model. |
