    Description

      QQuickMouseArea overrides QQuickItem::isEnabled and setEnabled, and has its own "d->enabled" property. This means that setting enabled to false doesn't propagate the state to its children.
      A simple fix would be to remove the overrides and rely on QQuickItem behavior, but I'm not sure i'm not missing some gotcha. Why does QQuickMouseArea reimplement them in the first place?

      Test case:

       
import QtQuick 2.0

//Item {
MouseArea {
    id: root
    width: 200
    height: 200
    enabled: false

    Item {
        id: child
    }

    Component.onCompleted: console.log(root.enabled, child.enabled)
}

      With the MouseArea as the root item the output is "false true", while with the Item as the root it is "false false"
