class watson.events.types.Event(name, target=None, params=None)

A base event that can be subclassed for use with an EventDispatcher.

Example:

def my_listener(event):
    print(event.params['config'])

dispatcher.add('MyEvent', my_listener)

event = Event('MyEvent')
event.params['config'] = {'some': 'config'}
dispatcher.trigger(event)

__init__(name, target=None, params=None)

Initializes the event.

Initialize the Event based on an event name. The name will be used when the event is triggered from the event dispatcher.

Parameters:

• name (string) – the name of the event
• target (mixed) – the originating target of the event
• params (dict) – the params associated with the event

stop_propagation()

Prevents the event from triggering any more event listeners.

This should be used within an event listener when you wish to halt any further listeners from being triggered.

stopped

Return whether or not the event has been stopped.
