## Detailed Description

An AtkStateSet determines a component's state set.

It is composed of a set of Atk::States.

## Member Function Documentation

bool Atk::StateSet::add_state | ( | Atk::StateType | type | ) |

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

Parameters:

  type | An Atk::StateType.

Returns:
  `true` if the state for type is not already in set.

Glib::RefPtr<StateSet> Atk::StateSet::and_sets | ( | const Glib::RefPtr< StateSet >& | compare_set | ) |

Constructs the intersection of the two sets, returning `0` if the intersection is empty.

Parameters:

  compare_set | Another Atk::StateSet.

Returns:
  A new Atk::StateSet which is the intersection of the two sets.

bool Atk::StateSet::contains_state | ( | Atk::StateType | type | ) |

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

Parameters:

  type | An Atk::StateType.

Returns:
  `true` if type is the state type is in set.

bool Atk::StateSet::is_empty | ( |  | ) | const

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

Returns:
  `true` if set has no states set, otherwise `false`.

Glib::RefPtr<StateSet> Atk::StateSet::or_sets | ( | const Glib::RefPtr< StateSet >& | compare_set | ) |

Constructs the union of the two sets.

Parameters:

  compare_set | Another Atk::StateSet.

Returns:
  A new Atk::StateSet which is the union of the two sets, returning `0` is empty.

bool Atk::StateSet::remove_state | ( | Atk::StateType | type | ) |

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

Parameters:

  type | An Atk::Type.

Returns:
  `true` if type was the state type is in set.

Glib::RefPtr<StateSet> Atk::StateSet::xor_sets | ( | const Glib::RefPtr< StateSet >& | compare_set | ) |

Constructs the exclusive-or of the two sets, returning `0` is empty.

The set returned by this operation contains the states in exactly one of the two sets.

Parameters:

  compare_set | Another Atk::StateSet.

Returns:
  A new Atk::StateSet which contains the states which are in exactly one of the two sets.

## Friends And Related Function Documentation

Glib::RefPtr< Atk::StateSet > wrap | ( | AtkStateSet * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
