I have custom context menu for ui_sketch_textbox , this context menu is working and this is the code for it.

void MainWindow::on_ui_sketch_textbox_customContextMenuRequested(const QPoint& pos)
{
    QMenu* pMenu = new QMenu(this);

   
    QAction* pChildren = new QAction(tr("Children "), this);
    QAction* pDescendants = new QAction(tr("Descendants "), this);
    QAction* pSubtree = new QAction(tr("Subtree "), this);
    QAction* pScan_Descendants = new QAction(tr("List Descendants using Treewalk "), this);
    QAction* pScan_Ancestors = new QAction(tr("List Ancestors using Treewalk "), this);

  
    pMenu->addAction(pChildren);
    pMenu->addAction(pDescendants);
    pMenu->addAction(pSubtree);
    pMenu->addAction(pScan_Descendants);
    pMenu->addAction(pScan_Ancestors);

   

    connect(pScan_Ancestors, SIGNAL(triggered()), this, SLOT(ScanAncestors()));
    connect(pScan_Descendants, SIGNAL(triggered()), this, SLOT(ScanDescendants()));
    connect(pChildren, SIGNAL(triggered()), this, SLOT(ChildrenLogic()));
    connect(pDescendants, SIGNAL(triggered()), this, SLOT(DescendantsLogic()));
    connect(pSubtree, SIGNAL(triggered()), this, SLOT(SubtreeLogic()));
   

    pMenu->exec(cursor().pos());

    //Release the memory
    QList<QAction*> list = pMenu->actions();
    foreach(QAction * pAction, list) delete pAction;

    delete pMenu;

}

but i am trying to create another context menu for QListWidget named "elem_list" this is not working/doesnt show up when i right click

this is the code for it

void MainWindow::on_elem_list_customContextMenuRequested(const QPoint& pos)
{
    QMenu* sMenu = new QMenu(this);

    QAction* showTree = new QAction(tr("Show Tree "), this);

    sMenu->addAction(showTree);

    sMenu->exec(cursor().pos());

    delete sMenu;

}

how do i get the second context menu working ??
