      You need to create some actions in your dialog e.g. in the constructor:

      @
      // In the header file:
      QAction *myAction;

      //Cpp file:
      myAction = new QAction(tr("&My Action"), this);
      myAction->setIcon(QIcon(":/aCool.png"));
      myAction->setShortcut(tr("Ctrl+M"));
      myAction->setStatusTip(tr("My action demo"));
      connect(myAction, SIGNAL(triggered()), this, SLOT(mySlot()));
      

      // Then add it to your treeWidget:
      treeWidget->addAction(myAction);

      @

        You also need to set
        @
        treeWidget->setContextMenuPolicy(Qt::ActionsContextMenu);
        @

        If you need to have different context menu for some of the items in the tree, you need to connect the itemSelectionChanged() signal to a slot where you remove/adds actions according to your needs.
