Description

An atk.StateSet determines a component's state set. It is composed of a set of ATK states specified using the Atk State Type Constants.

Constructor

atk.StateSet

    atk.StateSet()

Returns :

a new atk.StateSet

Creates a new empty state set.

Methods

atk.StateSet.is_empty

    def is_empty()

Returns :

True if the set has no states set, otherwise False

Checks whether the state set is empty, i.e. has no states set.

atk.StateSet.add_state

    def add_state(type)

`type` :	one of the Atk State Type Constants
Returns :	`True` if the state for `type` is not already in the set.

Add a new state for the specified type to the current state set if it is not already present.

atk.StateSet.add_states

    def add_states(types)

types :

a sequence of Atk State Type Constants.

Add the states for the specified types to the current state set.

atk.StateSet.clear_states

    def clear_states()

Removes all states from the state set.

atk.StateSet.contains_state

    def contains_state(type)

`type` :	one of the Atk State Type Constants.
Returns :	`True` if `type` is the state type is in the set.

Checks whether the state for the specified type is in the specified set.

atk.StateSet.contains_states

    def contains_states(types)

`types` :	a sequence of Atk State Type Constants
Returns :	`True` if all the states in `types` are in the set.

Checks whether the states for all the specified types are in the specified set.

atk.StateSet.remove_state

    def remove_state(type)

`type` :	one of the Atk State Type Constants
Returns :	`True` if `type` was in the set.

Removes the state for the specified type from the state set.

atk.StateSet.and_sets

    def and_sets(compare_set)

`compare_set` :	another `atk.StateSet`
Returns :	a new `atk.StateSet` which is the intersection of the two sets.

Constructs the intersection of the two sets, returning None if the intersection is empty.

atk.StateSet.or_sets

    def or_sets(compare_set)

`compare_set` :	another `atk.StateSet`
Returns :	a new `atk.StateSet` which is the union of the two sets, returning `None` is empty.

Constructs the union of the two sets.

atk.StateSet.xor_sets

    def xor_sets(compare_set)

`compare_set` :	another `atk.StateSet`
Returns :	a new `atk.StateSet` which contains the states which are in exactly one of the two sets.

Constructs the exclusive-or of the two sets, returning None is empty. The set returned by this operation contains the states in exactly one of the two sets.

Functions

atk.state_type_register

    def atk.state_type_register(name)

`name` :	a character string describing the new state.
Returns :	a new state type value for the new state.

Registers a new object state and adds it to the Atk State Type Constants.

atk.state_type_get_name

    def atk.state_type_get_name(type)

`type` :	one of the Atk State Type Constants.
Returns :	the string describing the state type

Gets the description string describing the state type specified bytype.

atk.state_type_for_name

    def atk.state_type_for_name(name)

`name` :	a character string state name
Returns :	one of the Atk State Type Constants.

Gets the state type corresponding to the description string name.
