如何显示从QTimeEdit到相应LCD的小时、分钟值？

Question

我用QTimeEdit编辑时间。但当我点击“确定”时，输出是小时：16分钟：8，不管我在QTimeEdit中输入什么数字。因此，我想知道必须添加什么函数来更正QTimeEdit中的设置时间。在

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不表示时间和分钟，而是表示QTimeEdit的sections。相反，您应该使用time()方法获取时间，使用后者分别使用hour()和{a4}获得小时和分钟。在

另外，您不应该像PyQt所指出的那样修改Qt设计器生成的代码，而是应该创建另一个继承自相应小部件并将初始类用作接口的类。更多信息，我建议阅读this。在

显然比eyllanesc慢一点，而且有足够大的差异可以发布它。备注是一样的。在

就我个人而言，我更喜欢政治公众人物文件建议的进口声明，以及在其自身职能中建立联系的监督机制。在
