ok so I found the method connected to the signal of the button.

 The button is 'autoBtn' and is connected to the 'autoBtnClicked' slot, 
which, calls the viewbox 'enableAutoRange' method. For what I wanted I had 
to rewrite the 'autoBtnClicked' method and play around the 'state' 
dictionary... very painful.

 The button can be disbled by the "disableButtons" method on the PloItem 
class.
