## 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 | ) |

Adds the state of the specified type to the state set if it is not already present.

Note that because an Atk::StateSet is a read-only object, this method should be used to add a state to a newly-created set which will then be returned by #atk_object_ref_state_set. It should not be used to modify the existing state of an object. See also #atk_object_notify_state_change.

Parameters

  type | An Atk::StateType.

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

void Atk::StateSet::add_states | ( | const Glib::ArrayHandle< Atk::StateType >& | types | ) |

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

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

Parameters

  compare_set | Another Atk::StateSet.

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

void Atk::StateSet::clear_states | ( |  | ) |

Removes all states from the state set.

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.

static GType Atk::StateSet::get_type | ( |  | ) |

static

Get the GType for this class, for use with the underlying GObject type system.

AtkStateSet* Atk::StateSet::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

const AtkStateSet* Atk::StateSet::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

AtkStateSet* Atk::StateSet::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

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`.

StateSet& Atk::StateSet::operator= | ( | StateSet&& | src | ) |

noexcept

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 `nullptr` is empty.

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

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

Note that because an Atk::StateSet is a read-only object, this method should be used to remove a state to a newly-created set which will then be returned by #atk_object_ref_state_set. It should not be used to modify the existing state of an object. See also #atk_object_notify_state_change.

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 `nullptr` 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.

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.
