Implemented Interfaces

GooCanvasRectModel implements GooCanvasItemModel.

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”.)

Functions

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.

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

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

Parameters

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.	[skip]
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.
