Description
GooCanvasRect represents a rectangle item.
It is a subclass of GooCanvasItemSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width".
It also implements the GooCanvasItem interface, so you can use the
GooCanvasItem functions such as goo_canvas_item_raise() and
goo_canvas_item_rotate().
To create a GooCanvasRect use goo_canvas_rect_new().
To get or set the properties of an existing GooCanvasRect, use
g_object_get() and g_object_set().

typedef struct _GooCanvasRect GooCanvasRect;
The GooCanvasRect struct contains private data only.

Creates a new rectangle item.
|
the parent item, or NULL. If a parent is specified, it will assume
ownership of the item, and the item will automatically be freed when it is
