PYQT5如何按日期"mon"、"tues"等打开新的window

Question

如何在日历上选择日期后打开新的 window？我在哪里可以根据日期打开不同的windows？

下面是我的代码：我试过使用 if-else 但无法获取数据。如何通过读取获取日历数据的标签中的单词来打开新的 window？

class Window(QWidget):

    def __init__(self):
        super().__init__()

        self.left, self.top, self.width, self.height = 600, 100, 500, 480

        self.page1 = self.create_page1()
        self.page2 = self.create_page2()

        self.stack = QStackedWidget()
        self.stack.addWidget(self.page1)
        self.stack.addWidget(self.page2)

        hbox = QHBoxLayout(self)
        hbox.addWidget(self.stack)
        self.setLayout(hbox)

        self.show_page1()

        self.show()


    def create_page1(self):
        page = QWidget()


        page.calendar = QCalendarWidget(page)
        page.calendar.setGridVisible(True)
        page.calendar.selectionChanged.connect(self.onSelectionChanged)

        page.label = QLabel(page)
        #page.label.setFont(QtGui.QFont("Sanserif", 10))
        page.label.setStyleSheet('color: blue;')

        page.proceedbutton = QPushButton("Proceed to select time", page)
        page.proceedbutton.setToolTip("<h3>Start the Session</h3>")
        page.proceedbutton.setEnabled(False)
        page.proceedbutton.clicked.connect(self.show_page2)

        page.backbutton = QPushButton("Back", page)
        page.backbutton.setToolTip("<h3>Start the Session</h3>")

        page.comboBox = None

        page.grid = QGridLayout(page)
        page.grid.addWidget(page.calendar, 0, 0, 1, 3)
        page.grid.addWidget(page.label, 1, 0, 1, 3)
        page.grid.addWidget(page.backbutton, 2, 1, 1, 1)
        page.grid.addWidget(page.proceedbutton, 2, 2, 1, 1)

        return page

    def create_page2(self):
        page = QWidget()

        layout = QFormLayout(page)

        page.comboBox = QComboBox(page)
        page.comboBox.addItems(["choose time", "0700", "0800"])
        page.comboBox.activated[str].connect(self.onComboActivated)
        layout.addRow('Choose Time', page.comboBox)

        page.viewbutton = QPushButton("View Stalls", page)
        page.viewbutton.setEnabled(False)
        page.viewbutton.clicked.connect(self.show_page3)
        layout.addRow(page.viewbutton)

        page.reselectdatebutton = QPushButton("Return to re-select date", page)
        page.reselectdatebutton.clicked.connect(self.show_page1)
        layout.addRow(page.reselectdatebutton)

        return page


    def show_page1(self):
        self.setWindowTitle("Select date from calendar")
        self.setGeometry(self.left, self.top, self.width, self.height)
        self.stack.setCurrentIndex(0)

    def show_page2(self):
        self.setWindowTitle("Select Time")
        self.setGeometry(600, 100, 500, 480)

        self.stack.setCurrentIndex(1)

    def show_page3(self):
        self.setWindowTitle("View Stalls")
        self.setGeometry(600, 100, 500, 480)
        self.stack.setCurrentIndex(2)



    def onSelectionChanged(self):

        ca = self.page1.calendar.selectedDate()
        self.page1.label.setText(ca.toString())
        print(ca.toString())
        self.page1.proceedbutton.setEnabled(True)


    def onComboActivated(self, text):
        print("choose time: {}".format(text))
        self.page2.viewbutton.setEnabled(True)


if __name__ == '__main__':
    App = QApplication([])
    window = Window()
    window.show()
    sys.exit(App.exec())

如果您需要根据工作日执行不同的操作，您需要做的就是将 clicked 信号连接到将使用 QCalendar.selectedDate().dayOfWeek() 的函数（它有一个range(1, 8)).

class Window(QWidget):
    # ...
    def create_page3(self):
        # ...
        page.viewmenubutton.clicked.connect(self.openviewforday)

    def openviewforday(self):
        weekDay = self.page1.calendar.selectedDate().dayOfWeek()
        if weekDay == 1:
            # do something for Monday
        elif weekDay == 2:
            # do something for Tuesday
        # etc...
