Details

class GooCanvas.CanvasItemModelIface

#GooCanvasItemModelIFace holds the virtual methods that make up the GooCanvas.CanvasItemModel interface.

Simple item models only need to implement the get_parent(), set_parent() and create_item() methods.

Items that support transforms should also implement get_transform() and set_transform(). Items that support styles should implement get_style() and set_style().

Container items must implement get_n_children() and get_child(). Containers that support dynamic changes to their children should implement add_child(), move_child() and remove_child(). Layout containers like GooCanvas.CanvasTable may implement get_child_property() and set_child_property().
