QML元素 - 转自（henreash的专栏 - 博客频道 - CSDN.NET）
这是Qt Quick子部分的QML元素的功能分组列表.
These are the functionally grouped lists of QML elements as part of Qt Quick.
声明元素时要带有名称和两个花括号.元素可能被嵌入到其他元素中,从而在两个元素间创建了父子关系.
Elements are declared with the their name and two curly braces. Elements may be nested in elements, thereby creating a parent-child relationship between the two elements.
要查看QML元素的功能列表,请见Groups Of Related QML Elements
