QML自定义的日历控件

        QML中提供了日历的控件Calendar，但该控件为QtQuick.Controls 1中提供的控件，因此只能使用QtQuick.Controls.Styles的方式对该控件进行设置，效果如图：

        在Qt文档中关于日历Calendar的描述为：Calendar允许从天数网格中选择日期，类似于QCalendarWidget。日历上的日期可以用鼠标选择，也可以用键盘导航。CalendarStyle 可用于设置日历组件的样式，其样式组件区域为：

    property color backgroundColor: 设置日历整体背景颜色，可设置半透明效果
    property color backgroundBorderColor: 背景边框颜色
    property color navigationBarBackgroundColor: 导航栏背景颜色
    property color navigationBarTextColor: 导航栏字体颜色
    property color dayOfWeekBackgroundColor: 星期显示栏背景颜色
    property color dayOfWeekTextColor:星期显示栏字体颜色
    property color daySelectedBackgroundColor: 选中的日期的背景颜色
    property color dayInvalidBackgroundColor:  非本月日期的背景颜色
    property color dayTextColor: 本月日期字体颜色
    property color gridLineColor: 日期框颜色

         大家在使用过程中可结合我QML中提供的属性和文档进行自定义日历样式和添加修改属性，QML源码：
