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.
