## Description

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".)

## Details

### struct GooCanvasRectModel

    struct GooCanvasRectModel;

The GooCanvasRectModel struct contains private data only.

### goo_canvas_rect_model_new ()

    GooCanvasItemModel * goo_canvas_rect_model_new          (GooCanvasItemModel *parent,
                                                             gdouble x,
                                                             gdouble y,
                                                             gdouble width,
                                                             gdouble height,
                                                             ...);

Creates a new rectangle item.

`parent` : | 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 call `g_object_unref()` to free it. [skip]
`x` : | the x coordinate of the left of the rectangle.
`y` : | the y coordinate of the top of the rectangle.
`width` : | the width of the rectangle.
`height` : | the height of the rectangle.
`...` : | optional pairs of property names and values, and a terminating `NULL`.
Returns : | a new rectangle model. [transfer full]

Here's an example showing how to create a rectangle at (100,100) with a width of 200 and a height of 100.
