Implemented Interfaces

GooCanvasRect implements GooCanvasItem.

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().

Functions

goo_canvas_rect_new ()

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

Creates a new rectangle item.

                                           "line-width", 5.0,
                                           "fill-color", "blue",
                                           NULL);
