Glib::RefPtr<Alpha> Clutter::Behaviour::get_alpha | ( |  | ) |

Retrieves the Clutter::Alpha object bound to behave.

Since cluttermm 0.2:

Returns:
  A Clutter::Alpha object, or `0` if no alpha object has been bound to this behaviour.

Glib::RefPtr<const Alpha> Clutter::Behaviour::get_alpha | ( |  | ) | const

Retrieves the Clutter::Alpha object bound to behave.

Since cluttermm 0.2:

Returns:
  A Clutter::Alpha object, or `0` if no alpha object has been bound to this behaviour.

int Clutter::Behaviour::get_n_actors | ( |  | ) | const

Gets the number of actors this behaviour is applied too.

Since cluttermm 0.2:

Since cluttermm 0.2:

Parameters:

  | index | The index of an actor this behaviour is applied too.

Returns:
  A Clutter actor or `0` if index is invalid.

Glib::RefPtr<const Actor> Clutter::Behaviour::get_nth_actor | ( | int | index | ) | const

Gets an actor the behaviour was applied to referenced by index num.

Since cluttermm 0.2:

Parameters:

  | index | The index of an actor this behaviour is applied too.

Returns:
  A Clutter actor or `0` if index is invalid.

const ClutterBehaviour* Clutter::Behaviour::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

Reimplemented in Clutter::BehaviourDepth, Clutter::BehaviourEllipse, Clutter::BehaviourOpacity, Clutter::BehaviourRotate, and Clutter::BehaviourScale.

ClutterBehaviour* Clutter::Behaviour::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

Reimplemented in Clutter::BehaviourDepth, Clutter::BehaviourEllipse, Clutter::BehaviourOpacity, Clutter::BehaviourRotate, and Clutter::BehaviourScale.

ClutterBehaviour* Clutter::Behaviour::gobj_copy | ( |  | ) |

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

Reimplemented in Clutter::BehaviourDepth, Clutter::BehaviourEllipse, Clutter::BehaviourOpacity, Clutter::BehaviourRotate, and Clutter::BehaviourScale.

bool Clutter::Behaviour::is_applied | ( | const Glib::RefPtr< Actor >& | actor | ) |

Check if behave applied to actor.

Since cluttermm 0.4:

Parameters:

  | actor | A Clutter::Actor.

Returns:
  `true` if actor has behaviour. `false` otherwise.

virtual void Clutter::Behaviour::on_applied | ( | const Glib::RefPtr< Actor >& | actor | ) | `[protected, virtual]`

virtual void Clutter::Behaviour::on_removed | ( | const Glib::RefPtr< Actor >& | actor | ) | `[protected, virtual]`

void Clutter::Behaviour::remove | ( | const Glib::RefPtr< Actor >& | actor | ) |

Removes actor from the list of Clutter::Actors to which behave applies.

This function removes a reference on the actor.

Since cluttermm 0.2:

Parameters:

  | actor | A Clutter::Actor.

void Clutter::Behaviour::remove_all | ( |  | ) |

Removes every actor from the list that behave holds.

Since cluttermm 0.4:

void Clutter::Behaviour::set_alpha | ( | const Glib::RefPtr< Alpha >& | alpha | ) |

Binds alpha to a Clutter::Behaviour.

The Clutter::Alpha object is what makes a behaviour work: for each tick of the timeline used by Clutter::Alpha a new value of the alpha parameter is computed by the alpha function; the value should be used by the Clutter::Behaviour to update one or more properties of the actors to which the behaviour applies.

If alpha is not `0`, the Clutter::Behaviour will take ownership of the Clutter::Alpha instance.

Since cluttermm 0.2:

Parameters:

  | alpha | A Clutter::Alpha or `0` to unset a previously set alpha.
