Flickable does not react to the movement of the mouse

[Dmitry89]

When I try to move Flickable with the mouse, it does not move and it does not respond to the mouse wheel, how to enable Flickable dragging?

@ScrollView {
id: scrollview
anchors.fill: parent
flickableItem.dragging: true //<--here is Flickable
Rectangle {
color: "orange"
width: scrollview.viewport.width
height: 2000
}
}@

ERROR: Invalid property assignment: "dragging" is a read-only property
