Question on Qt animation framework

[Hugo Pereira Da Costa]

Hi all,
I have a technical question concerning animations.
All over the place in oxygen QPropertyAnimations trigger updates of widgets 
with a slot/signal call a la: 

connect( 
  animation, SIGNAL( valueChanged( const QVariant& ) ),
  widget, SLOT( update( void ) ) );

Now, I also added: 

connect( 
	animation, SIGNAL( finished( void ) ), 
	widget, SLOT( update( void ) ) );
	
The question is: does anyone know whether the second call necessary or 
superfluous, or in otherr words, when an animation runs, is it certified that it 
will always call a valueChanged signal with its endValue() before finishing. 

I guess I can test it, but in case anyone knows that on top of his/her mind, 
that would spare me some nasty QDebug

Thanks in advance,

Hugo
