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.

goo_canvas_rect_new ()

GooCanvasItem*      goo_canvas_rect_new                 (GooCanvasItem *parent,
                                                         gdouble x,
                                                         gdouble y,
                                                         gdouble width,
                                                         gdouble height,
                                                         ...);

Creates a new rectangle item.

parent :

 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 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 item.

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

 GooCanvasItem *rect = goo_canvas_rect_new (mygroup, 100.0, 100.0, 200.0, 100.0,
                                            "stroke-color", "red",
                                            "line-width", 5.0,
                                            "fill-color", "blue",
                                            NULL);
