              AbstractContainerWidget

Known Subclasses:

An abstract class for canvas widgets that contain a single child, such as BoxWidget and OvalWidget. Subclasses must define a constructor, which should create any new graphical elements and then call the AbstractCanvasContainer constructor. Subclasses must also define the _update method and the _tags method; and any subclasses that define attributes should define __setitem__ and __getitem__.
