QTreeWidget right click menu

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?

First you should set the context menu policy to CustomContextMenu:

treeView->setContextMenuPolicy(Qt::CustomContextMenu);

Then you can connect to the QWidget::customContextMenuRequested(const QPoint&) signal and show your context menu.
