Wraps an AT-SPI device event with a more Pythonic interface. Primarily adds
a consume attribute which can be used to cease propagation of a device event.
@ivar consume: Should this event be consumed and not allowed to pass on to
observers further down the dispatch chain in this process or possibly
system wide?
@type consume: boolean
@ivar type: Kind of event, KEY_PRESSED_EVENT or KEY_RELEASED_EVENT
@type type: Accessibility.EventType
@ivar id: Serial identifier for this key event
@type id: integer
@ivar hw_code: Hardware scan code for the key
@type hw_code: integer
@ivar modifiers: Modifiers held at the time of the key event
@type modifiers: integer
@ivar timestamp: Time at which the event occurred relative to some platform
dependent starting point (e.g. XWindows start time)
@type timestamp: integer
@ivar event_string: String describing the key pressed (e.g. keysym)
@type event_string: string
@ivar is_text: Is the event representative of text to be inserted (True), or
of a control key (False)?
@type is_text: boolean

Wraps an AT-SPI event with a more Pythonic interface managing exceptions,
the differences in any_data across versions, and the reference counting of
accessibles provided with the event.
@note: All unmarked attributes of this class should be considered public
readable and writable as the class is acting as a record object.
@ivar consume: Should this event be consumed and not allowed to pass on to
observers further down the dispatch chain in this process?
@type consume: boolean
@ivar type: The type of the AT-SPI event
@type type: L{EventType}
@ivar detail1: First AT-SPI event parameter
@type detail1: integer
@ivar detail2: Second AT-SPI event parameter
@type detail2: integer
@ivar any_data: Extra AT-SPI data payload
@type any_data: object
@ivar host_application: Application owning the event source
@type host_application: Accessibility.Application
@ivar source_name: Name of the event source at the time of event dispatch
@type source_name: string
@ivar source_role: Role of the event source at the time of event dispatch
@type source_role: Accessibility.Role
@ivar source: Source of the event
@type source: Accessibility.Accessible

Extracts information from the provided event. If the event is a "normal"
event, pulls the detail1, detail2, any_data, and source values out of the
given object and stores it in this object. If the event is a device event,
key ID is stored in detail1, scan code is stored in detail2, key name,
key modifiers (e.g. ALT, CTRL, etc.), is text flag, and timestamp are
stored as a 4-tuple in any_data, and source is None (since key events are
global).
@param event: Event from an AT-SPI callback

Wraps the AT-SPI event type string so its components can be accessed
individually as klass (can't use the keyword class), major, minor, and detail
(klass:major:minor:detail).
@note: All attributes of an instance of this class should be considered
public readable as it is acting a a struct.
@ivar klass: Most general event type identifier (object, window, mouse, etc.)
@type klass: string
@ivar major: Second level event type description
@type major: string
@ivar minor: Third level event type description
@type minor: string
@ivar detail: Lowest level event type description
@type detail: string

Parses the full AT-SPI event name into its components
(klass:major:minor:detail). If the provided event name is an integer
instead of a string, then the event is really a device event.
@param name: Full AT-SPI event name
@type name: string
@raise AttributeError: When the given event name is not a valid string
