GooCanvasRectModel represents a model for rectangle items.
It is a subclass of GooCanvasItemModelSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width".
It also implements the GooCanvasItemModel interface, so you can use the
GooCanvasItemModel functions such as goo_canvas_item_model_raise() and
goo_canvas_item_model_rotate().
To create a GooCanvasRectModel use goo_canvas_rect_model_new().
To get or set the properties of an existing GooCanvasRectModel, use
g_object_get() and g_object_set().
To respond to events such as mouse clicks on the rectangle you must connect
to the signal handlers of the corresponding GooCanvasRect objects.
(See goo_canvas_get_item() and "item-created".)
typedef struct _GooCanvasRectModel GooCanvasRectModel;
The GooCanvasRectModel struct contains private data only.
GooCanvasItemModel* goo_canvas_rect_model_new (GooCanvasItemModel *parent,gdouble x,gdouble y,gdouble width,gdouble height,...);
Creates a new rectangle item.
| 
 | 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 callg_object_unref()to free it. | 
| 
 | the x coordinate of the left of the rectangle. | 
| 
 | the y coordinate of the top of the rectangle. | 
| 
 | the width of the rectangle. | 
| 
 | the height of the rectangle. | 
| 
 | optional pairs of property names and values, and a terminating NULL. | 
| Returns : | a new rectangle model. | 
Here's an example showing how to create a rectangle at (100,100) with a width of 200 and a height of 100.
