【问题描述】：
我目前正在创建一个 QML 日历，它可以理想地显示来自 Google 日历的事件。
这是我想在 python 中模拟的示例： https://doc.qt.io/qt-5.9/qtquickcontrols-calendar-example.html
现在，一个 python 文件正在从 Google Calendar API 获取日期和事件摘要，并将它们作为 {date: event summary} 的字典（python 代码中的 tenevents 变量）返回。我有一个非常简单的 QML 窗口，显示一个日历和一个矩形。我想单击日历上的某个日期，并让该日期的事件显示在矩形中，并标记有事件的日期。我想我有我需要的大部分数据，我只是不知道如何使用它。我不确定如何在点击时提取日期信息，也不确定如何传递 python 字典并显示我想要的内容——我感谢任何指向有用文档的方向和/或指针！
我在下面包含了我的代码！
getevents() 返回如下内容：
{'2020-07-30T13:00:00-05:00': 'Buy a Single Olive', '2020-07-31T10:00:00-05:00': 'Jarvis', '2020-08-02': 'Peel an Apple', '2020-08-04T02:30:00-05:00': 'Eat Two Crisp Grapes'}
