如何在PyQt5中为对话框添加最小化和最大化图标？

Question

我是PyQt5的初学者。我在dialog中开发了一些应用程序，但后来我注意到dialog中没有最小化和最大化图标默认。如何我能在对话框里找到这个吗。 任何建议都会被采纳很有帮助。谢谢提前。你知道吗

class Ui_ZValue(object):
    def setupUi(self, ZValue):
        ZValue.setObjectName("ZValue")
        ZValue.resize(400, 300)
        self.lineEdit = QtWidgets.QLineEdit(ZValue)
        self.lineEdit.setGeometry(QtCore.QRect(130, 70, 131, 41))
        self.lineEdit.setObjectName("lineEdit")
        self.pushButton = QtWidgets.QPushButton(ZValue)
        self.pushButton.setGeometry(QtCore.QRect(130, 150, 131, 41))
        self.pushButton.setObjectName("pushButton")

        self.retranslateUi(ZValue)
        QtCore.QMetaObject.connectSlotsByName(ZValue)

    def retranslateUi(self, ZValue):
        _translate = QtCore.QCoreApplication.translate
        ZValue.setWindowTitle(_translate("ZValue", "Copy Z Cordinate"))
        self.pushButton.setText(_translate("ZValue", "Cofirm"))

        # self.ui.setWindowFlag(Qt.WindowMaximizeButtonHint, True)
        self.ui.setupUi(self)
        self.ui.pushButton.clicked.connect(self.dispmessage)

    def dispmessage(self):
        self.ui.lineEdit.setText("Clicked")

    w.show()
    sys.exit(app.exec_())

要获得QDialog的最大化和最小化按钮，需要分别设置窗口标志Qt.WindowMaximizeButtonHint和Qt.WindowMinimizeButtonHint，例如

dialog.setWindowFlag(Qt.WindowMinimizeButtonHint, True)
dialog.setWindowFlag(Qt.WindowMaximizeButtonHint, True)
