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.
Note
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.
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. |
