      Description

      In design studio there is a use case where a CheckBox can be "read-only". The user can't click on it, but they can click on an action indicator to the left of it that opens a menu. Currently the only way to achieve this is to use a MouseArea to block the CheckBox while the "readOnly" property is true. Using Binding to force the checked state doesn't work (you can still affect it by clicking on it):

      import QtQuick 2.12
      import QtQuick.Controls 2.12
      
      ApplicationWindow {
          width: 640
          height: 480
          visible: true
      
          CheckBox {
              id: checkBox
      
              property bool readOnly: true
      
              Binding {
                  target: checkBox
                  property: "checked"
                  value: false
                  when: checkBox.readOnly
              }
      
              Binding {
                  target: checkBox
                  property: "checkState"
                  value: Qt.Unchecked
                  when: checkBox.readOnly
              }
          }
      }
      

      Setting enabled to false is not an option because that then disables the action indicator (which is a child of the CheckBox).

      So we could add an interactive property which disables interaction with the control itself but not its children.
