Question

当我点击该日期时，我正在做的是这个日历，然后它将显示UI_tab的类，这是一个tabwidget，包括两个tabs.each选项卡包括一些标签和其他。但是它不能工作。

from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Tab(object):

    # create tabwidget  
    def __init__(self,parentw,*args):
        print(args)
        print(parentw)

        self.font.setUnderline(False)
        self.w=['title0','title1',

                w_in_tab[i].setText(self.wt[int(self.w.index(i)/2)])
            else:
                w_in_tab[i].setGeometry(QtCore.QRect(140, 180 +(self.w.index(i)-1)*25, 59, 25))

        scrollArea = QtWidgets.QScrollArea(parentw)
        scrollArea.setEnabled(True)
        scrollArea.setGeometry(QtCore.QRect(140, 7*25+180, 341, 440))

        scrollArea.setWidgetResizable(True)
        scrollArea.setObjectName("scrollArea")
        scrollAreaWidgetContents_2 = QtWidgets.QWidget()
        scrollAreaWidgetContents_2.setGeometry(QtCore.QRect(0, 0, 322, 1600))
        scrollAreaWidgetContents_2.setMinimumSize(QtCore.QSize(200, 1600))
        scrollAreaWidgetContents_2.setObjectName("scrollAreaWidgetContents_2")
        detail2 = QtWidgets.QTextBrowser(scrollAreaWidgetContents_2)
        detail2.setGeometry(QtCore.QRect(0, 0, 321, 600))
        detail2.setMinimumSize(QtCore.QSize(296, 192))
        detail2.setObjectName("detail2")
        scrollArea.setWidget(scrollAreaWidgetContents_2)






class Ui_MainWindow(object):
     # setup main ui include calendar
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(997, 707)
        MainWindow.setStyleSheet("")
        self.centralWidget = QtWidgets.QWidget(MainWindow)
        self.centralWidget.setObjectName("centralWidget")
        self.centralWidget.setUpdatesEnabled(True)
        self.calendarw = QtWidgets.QWidget(self.centralWidget)
        self.calendarw.setGeometry(QtCore.QRect(560, 20, 361, 541))
        self.calendarw.setObjectName("calendarw")
        self.cal = QtWidgets.QCalendarWidget(self.calendarw)
        self.cal.setGeometry(QtCore.QRect(0, 60, 361, 481))
        self.cal.setFirstDayOfWeek(QtCore.Qt.Monday)
        self.cal.setObjectName("cal")
        self.cal_la = QtWidgets.QLabel(self.calendarw)
        self.cal_la.setGeometry(QtCore.QRect(110, 20, 161, 31))
        font = QtGui.QFont()
        font.setPointSize(22)
        self.cal_la.setFont(font)
        self.cal_la.setAlignment(QtCore.Qt.AlignCenter)
        self.cal_la.setObjectName("cal_la")
        MainWindow.setCentralWidget(self.centralWidget)
        MainWindow.setWindowTitle("MainWindow")
        self.cal_la.setText("calendar")
        #  
        #  Ui_Tab(self.centralWidget)    
        # this makes me confused,I hope that when I clicked the date of the
        #   calendar ,then it will display the class of UI_tab.However it 
        # cant't work.
        self.cal.clicked.connect(lambda x :Ui_Tab(self.centralWidget))
        QtCore.QMetaObject.connectSlotsByName(MainWindow)


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

当我使用下面的代码时，它完全符合我的要求，但没有点击日历日期。

   Ui_Tab(self.centralWidget)

而不是

    self.cal.clicked.connect(lambda x :Ui_Tab(self.centralWidget))

Answer 1

访问PyQt Window No Show

我只是更改下面的代码

      self.cal.clicked.connect(lambda x :Ui_Tab(self.centralWidget))

到

       self.cal.clicked.connect(Ui_Tab(self.centralWidget).show)

在PyQt中添加和删除小部件
