Inheritance diagram for IPython.core.displaypub:
An interface for publishing rich data to frontends.
There are two components of the display system:
This module defines the logic display publishing. The display publisher uses the display_data message type that is defined in the IPython messaging spec.

Bases: IPython.config.configurable.Configurable
A traited class that publishes display data to frontends.
Instances of this class are created by the main IPython object and should be accessed there.
Create a configurable given a config config.
Parameters : | config : Config
|
---|
Notes
Subclasses of Configurable must call the __init__() method of Configurable before doing anything else and using super():
class MyConfigurable(Configurable):
def __init__(self, config=None):
super(MyConfigurable, self).__init__(config)
# Then any other code you need to finish initialization.
This ensures that instances will be configured properly.
Get the config class config section
Get the help string for this class in ReST format.
If inst is given, it’s current trait values will be used in place of class defaults.
Get the help string for a single trait.
If inst is given, it’s current trait values will be used in place of the class default.
Get the help string for a single trait and print it.
Get a list of all the names of this classes traits.
This method is just like the trait_names() method, but is unbound.
Get a list of all the traits of this class.
This method is just like the traits() method, but is unbound.
The TraitTypes returned don’t know anything about the values that the various HasTrait’s instances are holding.
This follows the same algorithm as traits does and does not allow for any simple way of specifying merely that a metadata name exists, but has any value. This is because get_metadata returns None if a metadata key doesn’t exist.
A trait whose value must be an instance of a specified class.
The value can also be an instance of a subclass of the specified class.
Setup a handler to be called when a trait changes.
This is used to setup dynamic notifications of trait changes.
Static handlers can be created by creating methods on a HasTraits subclass with the naming convention ‘_[traitname]_changed’. Thus, to create static handler for the trait ‘a’, create the method _a_changed(self, name, old, new) (fewer arguments can be used, see below).
Parameters : | handler : callable
name : list, str, None
remove : bool

Get a list of all the names of this classes traits.
Get a list of all the traits of this class.

Fire the traits events when the config is updated.
