How to create right click menu of submenu?

[sonichy]

I want a right click menu on submenu to delete QStringList item.

QStringList SL_bookmark_title,SL_bookmark_url;
QMenu *submenu = new QMenu;
for(int i=0;i<SL_bookmark_title.size();i++){
QAction *action_bookmark_title = new QAction(submenu);
action_bookmark_title->setText(SL_bookmark_title.at(i));
action_bookmark_title->setToolTip(SL_bookmark_url.at(i));
submenu->addAction(action_bookmark_title);
connect(action_bookmark_title,SIGNAL(triggered(bool)),this,SLOT(gotoBookmarkURL(bool)));
}
action_bookmark->setMenu(submenu);

@sonichy hi,friend,welcome

you can reimplemented void QWidget::contextMenuEvent(QContextMenuEvent *event) in a subclass to receive widget context menu events.

Add submenu functions

QAction *addMenu(QMenu *menu)
QMenu *addMenu(const QString &title)
QMenu *addMenu(const QIcon &icon, const QString &title)

code snippet:

void Widget::contextMenuEvent(QContextMenuEvent *event)
{
    QMenu menu;
    menu.addAction(tr("act 1"));
    menu.addAction(tr("act 2"));

    /** add submenu */
    QMenu* subMenu = menu.addMenu(tr("sub menu"));
    subMenu->addAction("sub act1");
    subMenu->addAction("sub act1");

    QAction*  selAct = menu.exec(event->globalPos());
    if(0 != selAct){
         ///< do something....
    }
    QWidget::contextMenuEvent(event);
}

@sonichy
for the menu's main level you can create a custom QMenu sublass.
Listen to the context menu event (as mentioned by @joeQ) in there and show a custom context-menu. Not sure if this works at all though.

For the sub-menu level this is gonna be harder, since the sub-menu is created from the QAction and thus needs further implementations.
