如何显示从QTimeEdit到相应的LCD的小时，分​​钟值？

Question

我使用QTimeEdit编辑时间。但是，当我单击“确定”时，输出是HOUR：16 MINUTE：8，无论我在QTimeEdit中输入多少。因此，我想知道我必须添加什么功能来更正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

Answer 1

HourSection和MinuteSection不代表时间和分钟，而是代表QTimeEdit的sections。相反，您应该使用time()方法获取时间，而使用后者的hour()和minute()分别获取小时和分钟。

此外，您不应该按照PyQt的指示修改Qt Designer生成的代码，而应该创建另一个类，该类继承自适当的小部件并使用初始类作为接口。有关更多信息，我建议阅读this。

显然，它比eyllanesc慢一些，并且差异很大，无论如何都可以发布它。备注相同。

我个人更喜欢PEP文档建议的导入语句，以及对在自己的功能中建立联系的监督。
