## Description

GooCanvasEllipseModel represents a model for ellipse 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 GooCanvasEllipseModel use `goo_canvas_ellipse_model_new()`.

To get or set the properties of an existing GooCanvasEllipseModel, use `g_object_get()` and `g_object_set()`.

To respond to events such as mouse clicks on the ellipse you must connect to the signal handlers of the corresponding GooCanvasEllipse objects. (See `goo_canvas_get_item()` and "item-created".)

## Details

### GooCanvasEllipseModel

    typedef struct _GooCanvasEllipseModel GooCanvasEllipseModel;

The GooCanvasEllipseModel struct contains private data only.

### goo_canvas_ellipse_model_new ()

    GooCanvasItemModel* goo_canvas_ellipse_model_new        (GooCanvasItemModel *parent,
                                                             gdouble center_x,
                                                             gdouble center_y,
                                                             gdouble radius_x,
                                                             gdouble radius_y,
                                                             ...);

Creates a new ellipse model.

`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.
`center_x` : | the x coordinate of the center of the ellipse.
`center_y` : | the y coordinate of the center of the ellipse.
`radius_x` : | the horizontal radius of the ellipse.
`radius_y` : | the vertical radius of the ellipse.
`...` : | optional pairs of property names and values, and a terminating `NULL`.
Returns : | a new ellipse model.

Here's an example showing how to create an ellipse centered at (100.0, 100.0), with a horizontal radius of 50.0 and a vertical radius of 30.0. It is drawn with a red outline with a width of 5.0 and filled with blue:

     GooCanvasItemModel *ellipse = goo_canvas_ellipse_model_new (mygroup, 100.0, 100.0, 50.0, 30.0,
                                                                 "stroke-color", "red",
                                                                 "line-width", 5.0,
                                                                 "fill-color", "blue",
                                                                 NULL);
