GooCanvas.CanvasItemSimpleClass

Fields

Name	Type	Access	Description
parent_class	GObject.ObjectClass	r
simple_create_path	object	r	GooCanvas.simple subclasses that draw basic shapes and paths only need to override this one method. It creates the path for the item. All updating, painting and hit-testing is provided automatically by the GooCanvas.CanvasItemSimple class. (This method is used by the builtin GooCanvas.CanvasEllipse, GooCanvas.CanvasRect and GooCanvas.CanvasPath items.) More complicated subclasses must override simple_update, simple_paint and simple_is_item_at instead.
simple_is_item_at	object	r	subclasses should override this to do hit-testing.
simple_paint	object	r	subclasses should override this to paint their item.
simple_update	object	r	subclasses should override this to calculate their new bounds, in user space.

The GooCanvas.CanvasItemSimpleClass-struct struct contains several methods that subclasses can override.

Simple items need only implement the create_path() method. More complex items must override the update(), paint() and is_item_at() methods instead.
