EDIT: I found the best solution in this post: link In your case it would be as simple as:

编辑：我在这篇文章中找到了最佳解决方案：链接在你的情况下，它将如下所示：

QMenu contextMenu(this);
QString menuStyle(
        "QMenu::item{"      
        "color: rgb(0, 0, 255);"
        "}"
    );
contextMenu.setStyleSheet(menuStyle);

PREVIOUS SOLUTION:
You can use QWidgetAction instead of QAction, and define your QLabel with text and stylesheet you want, and then assign it to your QWidgetAction. But keep in mind that you have to tweak the width and height of your QLabel, in order for it to look the same as QAction does.

以前的解决方案：您可以使用QWidgetAction而不是QAction，并使用您想要的文本和样式表定义QLabel，然后将其分配给您的QWidgetAction。但请记住，您必须调整QLabel的宽度和高度，以使其看起来与QAction相同。

Sample code:

示例代码：

// label
QLabel *text = new QLabel(QString("your text here"), this);
text->setStyleSheet("color: blue"); 
// init widget action
QWidgetAction *widAct= new QWidgetAction(this);
widAct->setDefaultWidget(text);
contextMenu.addAction(widAct);
