Qt5 custom context menu ignoring style sheet

Question

I have a two editor classes, say BaseEditor and AdvancedEditor. BaseEditor inherits from QPlaintTextEdit and its standard context menu follows my style sheet properly.

My AdvancedEditor now inherits from BaseEditor and reimplements the method void showContextMenu(const QPoint &point) to generate a custom context menu. In it I basically do the following:

void AdvancedEditor::showContextMenu(const QPoint &point)
{ 
    QMenu* pStandardMenu = createStandardContextMenu();

    QMenu* pMenu = new QMenu();

    [add various stuff to pMenu]

    connect(pSignalMapper, SIGNAL(mapped(const QString&)), this, SLOT(onContextMenuSelected(const QString&)));

    pMenu->addSeparator();
    pMenu->addActions(pStandardMenu->actions());
    pMenu->exec(mapToGlobal(point));
    delete pMenu;
}

This menu however is rendered in the default OS design despite me having the following part in my QSS style sheet (which is properly used for all other menus):

QMenu {
    background-color: white;
    border: 1px solid #4495D1;
    padding: 1px;
}

I tried adding a custom paintEvent() as described here without any luck: http://qt-project.org/forums/viewthread/25664/#117575. Do I need another PE_* type?

Set pMenu's parent widget to the one which has your stylesheet.
