## Detailed Description

CalendarModel provides a way of creating a range of MonthGrid instances. It is typically used as a model for a ListView that uses MonthGrid as a delegate.

     ListView {
         id: listview

         width: 200; height: 200
         snapMode: ListView.SnapOneItem
         orientation: ListView.Horizontal
         highlightRangeMode: ListView.StrictlyEnforceRange

         model: CalendarModel {
             from: new Date(2015, 0, 1)
             to: new Date(2015, 11, 31)
         }

         delegate: MonthGrid {
             width: listview.width
             height: listview.height

             month: model.month
             year: model.year
             locale: Qt.locale("en_US")
         }

         ScrollIndicator.horizontal: ScrollIndicator { }
     }

In addition to the `index` property, a list of model data roles are available in the context of each delegate:

model.month : int | The number of the month
model.year : int | The number of the year

The Qt Labs Calendar module uses 0-based month numbers to be consistent with the JavaScript Date type, that is used by the QML language. This means that `Date::getMonth()` can be passed to the methods as is. When dealing with month numbers directly, it is highly recommended to use the following enumeration values to avoid confusion.

Constant | Description
--- | ---
`Calendar.January` | January (0)
`Calendar.February` | February (1)
`Calendar.March` | March (2)
`Calendar.April` | April (3)
`Calendar.May` | May (4)
`Calendar.June` | June (5)
`Calendar.July` | July (6)
`Calendar.August` | August (7)
`Calendar.September` | September (8)
`Calendar.October` | October (9)
`Calendar.November` | November (10)
`Calendar.December` | December (11)

Note: Types in Qt.labs modules are not guaranteed to remain compatible in future versions.
