Embedded widget in QGraphicsView related Right Mouse Button Click Issue

I am embedding a list widget into a QGraphicsView (at some level). I
noticed that the mouse right click button event does not behave the same way
as it would if it were on a regular form.

Attached is a small sample that should demonstrate the issue.

Here is the testing procedure in general (observe the output to the
console):

1. When you run the sample, you will see a window with 3 items inside it
(one window will be embedded inside of a QGraphicsView and the other will be
a stand alone form for comparison).
2. Try left clicking on an item.
3. Try left clicking on another item.
4. Try right clicking on another item.
5. Try double right clicking on another item.
6. Try left clicking on an item then double right clicking on the same
item.
7. Try left clicking on an item then double right clicking on a different
item.
