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.
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.
Details
GooCanvasItemModelSimple
typedef struct {
GooCanvasItemModel *parent;
GooCanvasItemSimpleData simple_data;
} GooCanvasItemModelSimple;
The GooCanvasItemModelSimple struct contains the basic data needed to implement canvas item models.
GooCanvasItemModel * |
the parent model. |
GooCanvasItemSimpleData |
data used by the canvas item for viewing the model. |
