has_observers	Get whether the atom has observers for a given topic.
initialize()	A reimplemented initializer.
insert_children(before, insert)	Insert children into this object at the given location.
members()	Get the members dictionary for the type.
notifications_enabled	Get whether notification is enabled for the atom.

set_parent(parent)	Set the parent for this object.
suppress_notifications()	Disable member notifications within in a context.
traverse([depth_first])	Yield all of the objects in the tree, from this object down.
traverse_ancestors([root])	Yield all of the objects in the tree, from this object up.
unobserve	Unregister an observer callback for the given topic(s).

create_shape(parent)[source]¶

Create the shape for the control. This method should create and initialize the shape.

Parameters:

parentshape or None

The parent shape for the control.

Returns:

resultshape

The shape for the control.

get_shape()[source]¶

Retrieve the shape for display.

Returns:

shapeshape or None

The toolkit shape that was previously created by the call to ‘create_shape’ or None if the proxy is not active or the shape has been destroyed.
