Get the object of the whole quotation in observer

Question

I am doing this:

public function setQuoteShippingMethod (Varien_Event_Observer $observer) {
        $item = $observer->getEvent()->getQuoteItem();

       //to have more code
    }

but it takes the last item (product) in the quotation (i.e. I have 4 items). I want to take the object of the whole quotation (bundle product), so I manipulate its shipping method.

I am observing checkout_cart_product_add_after. The point is - I have a quotation in the Customer Account's quotes - and when you open(view) the quotation - you can click "Add to cart". That's where my method is caught.

Answer 1

Based on the comments it seams that this solves the problem:

$item = $observer->getEvent()->getQuoteItem();
$quote = $item->getQuote()
//do stuff with $quote
