pyside6 在窗体中右击菜单（上下文菜单）

思路

1. 先添加上下文策略
   self.setContextMenuPolicy(Qt.ContextMenuPolicy.ActionsContextMenu)
2. 添加QAction，并且链接方法
   self.copy = QAction('复制')
self.copy.triggered.connect(lambda: print('复制'))
3. 将所有的QAction都添加到窗体
   self.addActions([self.copy, self.paste])

代码

from PySide6.QtWidgets import QApplication, QWidget
from PySide6.QtGui import QAction
from PySide6.QtCore import Qt

class Mywindow(QWidget):
    def __init__(self):
        super().__init__()
        self.setContextMenuPolicy(Qt.ContextMenuPolicy.ActionsContextMenu)
        self.copy = QAction('复制')
        self.copy.triggered.connect(lambda: print('复制'))
        self.paste = QAction('粘贴')
        self.paste.triggered.connect(lambda: print('粘贴'))
        self.addActions([self.copy, self.paste])


if __name__ == '__main__':
    app = QApplication([])
    window = Mywindow()
    window.show()
    app.exec()

效果
