A list of objects. While not technically a basic type, QML also supports lists of object types. When used from QML, the engine automatically appends each value to the list.
For example, the Item class contains a list property named children that can be used like this:
Item { children: [ Item { id: child1 }, Rectangle { id: child2 }, Text { id: child3 } ] }
child1, child2 and child3 will all be added to the children list in the order in which they appear.
