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:

Item {
    id: root

    required property string colorKey
    required property int modelData

    width: 64
    height: 64

    MouseArea {
        id: mouseArea

        width: 64
        height: 64
        anchors.centerIn: parent

        drag.target: tile

        onReleased: parent = tile.Drag.target !== null ? tile.Drag.target : root

        Rectangle {
            id: tile

            width: 64
            height: 64
            anchors {
                verticalCenter: parent.verticalCenter
                horizontalCenter: parent.horizontalCenter

            color: root.colorKey

            Drag.keys: [ root.colorKey ]
            Drag.active: mouseArea.drag.active
            Drag.hotSpot.x: 32
            Drag.hotSpot.y: 32
            states: State {
                when: mouseArea.drag.active
                AnchorChanges {
                    target: tile
                    anchors {
                        verticalCenter: undefined
                        horizontalCenter: undefined

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

DropArea {
    id: dragTarget

    property string colorKey

    width: 64
    height: 64
    keys: [ colorKey ]

    Rectangle {
        id: dropRectangle

        anchors.fill: parent
        color: dragTarget.containsDrag ? "grey" : dragTarget.colorKey

The keys property of the DropArea will only allow an item to be dropped on it if it has a matching key in its Drag.keys property.

GridView Example

The GridView Example adds drag and drop to a GridView, allowing you to visually reorder the delegates without changing the underlying ListModel. It uses a DelegateModel to move a delegate item to the position of another item it is dragged over.

    model: DelegateModel {
        delegate: DropArea {
            id: delegateRoot
            required property color color

            width: 80
            height: 80

            onEntered: function(drag) {
                visualModel.items.move((drag.source as Icon).visualIndex, icon.visualIndex)

            property int visualIndex: DelegateModel.itemsIndex

            Icon {
                id: icon
                dragParent: root
                visualIndex: delegateRoot.visualIndex
                color: delegateRoot.color
