qt - TypeError：无法读取 qml 中未定义的属性“天”

Question

下面是我收到上述错误的代码片段。days是嵌套模型：

ApplicationWindow {
id:appWindow
width: 1000
height: 600
visible:true
flags:Qt.FramelessWindowHint
//color: "transparent"

 property var monthName:0
 property string notesText: monthlistModel.get(monthofdayCalendar.currentIndex).days.get(newdayCalendar.currentIndex).hours.get(dayList.currentIndex).notes

   Settings {
       property alias notesText: appWindow.notesText
   }

下面是listmodel嵌套模型：

                  ListModel{
                      id:monthlistModel
                      Component.onCompleted: {
                                 let months = [
                                                {
                                                        monthName: 0,
                                                        days: createDays(31) 
                                                },
                                                {
                                                        monthName: 1,
                                                        days: createDays(29)

如何解决上述错误？

一般来说，这非常需要一些重构。

除此之外，您的 ListModel 应该包含 ListElements，而不是 javascript 对象和嵌套数组。可能值得仔细阅读ListModel 文档。这是一个有点相关的问题，可以提供更多帮助。
