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

GooCanvasRectModel

typedef struct _GooCanvasRectModel 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.

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.

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