title: QTreeWidget right click menu
body: <p>I looked around and it seems that the problem is present not only for tree widget but also for other widgets. But in my case, I found a solution, although an incomplete one. I am adding actions to my tree widget, so that when you right click on it, a popup with these actions appears. However, when I add items to my tree widget and I right click on them, the same popup appears.
  What I would like to do is that when you right click on the tree widget, a tree widget popup menu appears and when you right click on items, another corresponding popup menu appears. Does anybody knows how to do this?</p>
