since you create multiple DrawingAreas with the same event name, so all 
objects individually will raise the hArea_DblClick event.
but there is one trick: the object that raised a particular event can be 
referred to from within the event handler by using the Last object. 
consequently Last will be a reference to the particular DrawingArea 
dblclicked.
