Constructor & Destructor Documentation

Xfc::Atk::ObjectSignals::ObjectSignals (  Object *  object  )  [protected]

Constructs a new ObjectSignals object. Parameters: object  An Atk::Object inheriting the Atk::ObjectSignals implementation. Reimplemented from Xfc::G::ObjectSignals.

Member Function Documentation

virtual void Xfc::Atk::ObjectSignals::on_active_descendant_changed (  void **  child  )  [virtual]

Called when there is a change in the 'active' child or children of the object, for instance when interior focus changes in a table or list. Parameters: child  The newly focused object.

virtual void Xfc::Atk::ObjectSignals::on_children_changed (  unsigned int  change_index, void *  changed_child )  [virtual]

Called when the number of children of the object changes. Parameters: change_index  The index of the added or removed child. changed_child  The child which was added or removed. The children_changed signal supports two details, "add" and "remove" which indicate whether a child was added or removed.

virtual void Xfc::Atk::ObjectSignals::on_focus_event (  bool  focus_in  )  [virtual]

Called when there is a focus event for an object. Parameters: focus_in  Indicates whether or not the focus event is is or out.

virtual void Xfc::Atk::ObjectSignals::on_property_change (  AtkPropertyValues *  values  )  [virtual]

Called when the value of an object property changes. Parameters: values  The new value of the property which changed.

virtual void Xfc::Atk::ObjectSignals::on_state_change (  const String &  name, bool  state_set )  [virtual]

Called when the state of an object changes. Parameters: name  The name of the state which has changed. state_set  Indicates whether the state has been set or unset. This signal supports any of the accessible state types.
