Freeing allocated memory with Qt toolbars and actions
===

Do I need to free Qt toolbars and actions?

I created them this way

    QToolBar *tb = new QToolBar(this);
    tb->setWindowTitle(tr("Edit Actions"));
    addToolBar(tb);
    
    QAction *a;
    a = actionUndo = new QAction(...ecc..);

are these deallocated automatically or do I need to free them up?
