    \title QtQuick Examples - Drag and Drop
    \example quick/draganddrop
    \brief This is a collection of QML drag and drop examples
    \image qml-draganddrop-example.png

    This is a collection of small QML examples relating to drag and drop functionality.

    \section2 Tiles adds drag and drop to simple rectangles, which you can drag into a specific grid.

    It has a DragTile component which uses a MouseArea to move an item when dragged:

    \snippet examples/quick/draganddrop/tiles/DragTile.qml 0
    \snippet examples/quick/draganddrop/tiles/DragTile.qml 1

    And a DropTile component which the dragged tiles can be dropped onto:

    \snippet examples/quick/draganddrop/tiles/DropTile.qml 0

    The keys property of the DropArea will only allow an item with matching key in
    it's Drag.keys property to be dropped on it.

    \section2 GridView adds drag and drop to a GridView, allowing you to reorder the list.

    It uses a VisualDataModel to move a delegate item to the position of another item
    it is dragged over.
