\qmlattachedsignal QtQuick::Drag::dragStarted()

This signal is emitted when a drag is started with the \l startDrag() method or when it is started automatically using the \l dragType property.

\qmlattachedsignal QtQuick::Drag::dragFinished(DropAction dropAction)

This signal is emitted when a drag finishes and the drag was started with the \l startDrag() method or started automatically using the \l dragType property.

dropAction holds the action accepted by the target item.

\qmltype Drag \nativetype QQuickDrag \inqmlmodule QtQuick

For specifying drag and drop events for moved Items.

Using the Drag attached property, any Item can be made a source of drag and drop events within a scene.

When a drag is \l active on an item, any change in that item's position will generate a drag event that will be sent to any DropArea that intersects with the new position of the item. Other items which implement drag and drop event handlers can also receive these events.

The following snippet shows how an item can be dragged with a MouseArea. However, dragging is not limited to mouse drags; anything that can move an item can generate drag events, including touch events, animations and bindings.

import QtQuick
 
Item {
    width: 200; height: 200
 
    DropArea {
        x: 75; y: 75
        width: 50; height: 50
 
        Rectangle {
            anchors.fill: parent
            color: "green"
 
            visible: parent.containsDrag
        }
    }
 
    Rectangle {
        x: 10; y: 10
        width: 20; height: 20
        color: "red"
 
        Drag.active: dragArea.drag.active
        Drag.hotSpot.x: 10
        Drag.hotSpot.y: 10
 
        MouseArea {
            id: dragArea
            anchors.fill: parent
 
            drag.target: parent
        }
    }
}

A drag can be terminated either by canceling it with Drag.cancel() or setting Drag.active to false, or it can be terminated with a drop event by calling Drag.drop(). If the drop event is accepted, Drag.drop() will return the \l {supportedActions}{drop action} chosen by the recipient of the event, otherwise it will return Qt.IgnoreAction.
