~Observer()

virtual anatomist::Observer::~Observer ( )

virtual

Member Function Documentation

cleanupObserver()

virtual void anatomist::Observer::cleanupObserver ( )

protectedvirtual

call this function from inherited classes destructors.

Derived classes may have to manually call it, especially if they have overloaded unregisterObservable() otherwise it may be called by the destructor of a base class which will not be able to access the correct overloaded functions anymore.

It's not an error to call cleanupObserver() several times: basically each destructor in the inheritance tree of a derived class will call it, but only the first call will have any effect.

observed()

const std::set< Observable * > & anatomist::Observer::observed ( ) const

registerObservable()

virtual void anatomist::Observer::registerObservable ( Observable * )

protectedvirtual

only called by Observable: don't use this function directly

Reimplemented in anatomist::NormalsSettingsPanel::NormalsObserver.

unregisterObservable()

virtual void anatomist::Observer::unregisterObservable ( Observable * )

protectedvirtual

Called when an observable is destroyed, only called by Observable: don't use this function directly.

Reimplemented in ALandmarkPicker, anatomist::AObject, anatomist::AWindow, anatomist::ConstraintEditorWindow, anatomist::Fusion2D, anatomist::NormalsSettingsPanel::NormalsObserver, anatomist::RoiDynSegmentAction, anatomist::RoiManagementActionSharedData, ChooseReferentialWindow, ErpWraper, FixedPointOfViewWindow, Fusion2DWindow, Fusion3DWindow, GraphLandmarkPicker, LightModelWindow, MaterialWindow, QAPaletteWin, QAWindowBlock, QGraphProperties, QSurfMatchWin, QTexturePanel, QTextureWin, RenderingWindow, Tools3DWindow, VectorFieldEditionWindow, and VolRenderPanel.

update()

virtual void anatomist::Observer::update ( const Observable * observable, void * arg )

pure virtual

This method is called whenever the observed object is changed.

The programmer calls an observable object's notifyObservers method to have all the object's observers notified of the change.

Parameters

observable

the observable object
