我使用 QTimeEdit 来编辑时间。但是当我单击“确定”时，无论我在 QTimeEdit 中输入什么数字，输出都是 HOUR: 16 MINUTE: 8。因此，我想知道我必须添加什么函数来更正 QTimeEdit 中的设置时间。

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_EditTime(object):
    def setupUi(self, EditTime):
        EditTime.setObjectName("EditTime")
        EditTime.resize(392, 293)
        EditTime.setAutoFillBackground(False)
        self.timeEdit = QtWidgets.QTimeEdit(EditTime)
        self.timeEdit.setGeometry(QtCore.QRect(140, 160, 118, 22))
        self.timeEdit.setMaximumDateTime(QtCore.QDateTime(QtCore.QDate(1999, 12, 31), QtCore.QTime(23, 59, 59)))
        self.timeEdit.setMaximumDate(QtCore.QDate(1999, 12, 31))
        self.timeEdit.setMinimumDate(QtCore.QDate(1999, 12, 31))
        self.timeEdit.setMaximumTime(QtCore.QTime(23, 59, 59))
        self.timeEdit.setMinimumTime(QtCore.QTime(00, 00, 00))
        self.timeEdit.setCurrentSection(QtWidgets.QDateTimeEdit.HourSection)
        self.timeEdit.setTimeSpec(QtCore.Qt.OffsetFromUTC)
        self.timeEdit.setTime(QtCore.QTime(24,0,0))
        self.timeEdit.setObjectName("timeEdit")
        self.HourLCD = QtWidgets.QLCDNumber(EditTime)
        self.HourLCD.setGeometry(QtCore.QRect(60, 70, 111, 51))
        self.HourLCD.setObjectName("HourLCD")
        self.MinuteLCD = QtWidgets.QLCDNumber(EditTime)
        self.MinuteLCD.setGeometry(QtCore.QRect(200, 70, 111, 51))
        self.MinuteLCD.setObjectName("MinuteLCD")
        self.OK = QtWidgets.QPushButton(EditTime)
        self.OK.setGeometry(QtCore.QRect(160, 230, 75, 23))
        self.OK.setObjectName("OK")
        self.label = QtWidgets.QLabel(EditTime)
        self.label.setGeometry(QtCore.QRect(90, 46, 31, 20))
        self.label.setObjectName("label")
        self.label_2 = QtWidgets.QLabel(EditTime)
        self.label_2.setGeometry(QtCore.QRect(230, 50, 47, 13))
        self.label_2.setObjectName("label_2")

        self.retranslateUi(EditTime)
        QtCore.QMetaObject.connectSlotsByName(EditTime)
        self.OK.clicked.connect(self.connect)

    def connect(self):
        self.HourLCD.display(self.timeEdit.HourSection)
        self.MinuteLCD.display(self.timeEdit.MinuteSection)

我希望输出基于 QTimeEdit

HourSection 和 MinuteSection 不代表时间和分钟，而是 QTimeEdit 的部分。相反，您应该使用time()方法获取时间，并使用后者使用hour()和minute()分别获取小时和分钟。

此外，您不应像 PyQt 所指示的那样修改 Qt Designer 生成的代码，而应创建另一个继承自适当小部件并将初始类用作接口的类。有关更多信息，我建议阅读此。

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_EditTime(object):
    def setupUi(self, EditTime):
        EditTime.setObjectName("EditTime")
        EditTime.resize(392, 293)
        EditTime.setAutoFillBackground(False)
        self.timeEdit = QtWidgets.QTimeEdit(EditTime)
        self.timeEdit.setGeometry(QtCore.QRect(140, 160, 118, 22))
        self.timeEdit.setMaximumDateTime(QtCore.QDateTime(QtCore.QDate(1999, 12, 31), QtCore.QTime(23, 59, 59)))
        self.timeEdit.setMaximumDate(QtCore.QDate(1999, 12, 31))
        self.timeEdit.setMinimumDate(QtCore.QDate(1999, 12, 31))
        self.timeEdit.setMaximumTime(QtCore.QTime(23, 59, 59))
        self.timeEdit.setMinimumTime(QtCore.QTime(00, 00, 00))

    @QtCore.pyqtSlot()
    def onClicked(self):
        t = self.timeEdit.time()
        self.HourLCD.display(t.hour())
        self.MinuteLCD.display(t.minute())

显然比 eyllanesc 慢一点，并且有足够大的差异来发布它。备注是一样的。

就我个人而言，我更喜欢 PEP 文档建议的导入语句，以及在自己的功能中建立连接的监督。
