我遇到了同样的问题，我试图通过修改由调用方法QTextEdit::createStandardContext创建的标准上下文菜单来解决这个问题，但它确实起了作用。
代码如下：

void CWQTextEdit::contextMenuEvent(QContextMenuEvent *e)
{
    QMenu *menu = QTextEdit::createStandardContextMenu();
    if (menu == NULL)
        return QTextEdit::contextMenuEvent(e);

    QList<QAction*> actions = menu->actions();

    foreach (QAction *action, actions)
    {
       QString actionText = action->text();
       if (actionText.contains("Undo"))
       {
           actionText.replace("Undo", tr("Undo"));
           action->setText(actionText);
       }
       else if (actionText.contains("Redo"))
       {
           actionText.replace("Redo", tr("Redo"));
           action->setText(actionText);
       }
       else if (actionText.contains("Cu&t"))
       {
           actionText.replace("Cu&t", tr("Cut"));
           action->setText(actionText);
       }
       else if (actionText.contains("Copy"))
       {
           actionText.replace("Copy", tr("Copy"));
           action->setText(actionText);
       }
       else if (actionText.contains("Paste"))
       {
           actionText.replace("Paste", tr("Paste"));
           action->setText(actionText);
       }
       else if (actionText.contains("Delete"))
       {
           actionText.replace("Delete", tr("Delete"));
           action->setText(actionText);
       }
       else if (actionText.contains("Select All"))
       {
           actionText.replace("Select All", tr("Select All"));
           action->setText(actionText);
       }
    }

    menu->exec(e->globalPos());
}
