着色 PyQt5 QCalendarWidget 单元格并在单元格内打印数据

Question

根据要求，我需要创建一个用于任务管理的桌面应用程序。要求是以类似于 Outlook 日历的日历格式显示所有计划的活动。该应用程序还将有一些其他按钮，用于根据日历上的计划活动将用户重定向到相应的 URL。

我正在使用 python 的 PyQt5 模块开发这个桌面应用程序。我已经创建了所需的按钮，对于任务管理，我已经使用 QCalendarWidget 创建了日历。我还能够访问各个单元格，并能够根据日历上使用的点击来打印日期。

                self.top = 100
                self.left = 100
                self.width = 400
                self.height = 400
                self.InitWindow()

                self.header_groupBox = QGroupBox()
                self.header_groupBox.setLayout(gboxLayout)

                fileMenu = mainMenu.addMenu("File")
                helpMenu = mainMenu.addMenu("Help")

                exitAction = QAction('Exit', self)
                helpAction = QAction('About Us', self)

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

现在的要求是访问日历的每个单元格，如果有任何活动计划，则将其突出显示，并在单元格中提及活动名称，类似于 Outlook 日历。所有活动名称和时间表将作为输入在 Excel 表中给出。我可以访问日历单元格，但不确定如何突出显示单元格并打印单元格中的计划活动。

这可能吗？我是在正确的轨道上还是应该考虑其他一些方法？

Answer 1

子类QCalendarWidget并重新定义方法paintCell()。

例如，在您有事件的每个单元格中打印一个红点：

class Scheduler(QCalendarWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.events = {
            QDate(2019, 5, 24): ["Bob's birthday"],
            QDate(2019, 5, 19): ["Alice's birthday"]
        }

    def paintCell(self, painter, rect, date):
        super().paintCell(painter, rect, date)
        if date in self.events:
            painter.setBrush(Qt.red)
            painter.drawEllipse(rect.topLeft() + QPoint(12, 7), 3, 3)

Answer 2

我知道这是一个老问题，但是当我有一个类似的问题但提供的答案不起作用时，我被引导到这个问题，我设法得到了这个问题的答案来帮助我。我认为这可能会帮助任何需要帮助解决类似问题的人。

这是给我的代码：

        connection = sqlite3.connect("YourDatabase.db")
        crsr = connection.cursor()
        crsr.execute("""SELECT Date FROM CalendarTable""")

        date_format = "dd/MM/yyyy"
        cell_format = QtGui.QTextCharFormat()
        cell_format.setBackground(QtGui.QColor("lightblue"))

        for row in crsr.fetchall():
            date_str, *_ = row
            dt = QtCore.QDate.fromString(date_str, date_format)
            if dt.isValid():
                self.calendarWidget.setDateTextFormat(dt, cell_format)
            else:
                self.DateInfoOutput.setText("{} does not match format {}".format(date_str, date_format))

要在您的程序中使用此代码，您需要创建一个如下所示的数据库： The Database

这将输出如下： The Final Output
