  - ### addReadOnlyDisplayChangedHandler

    HandlerRegistration addReadOnlyDisplayChangedHandler(ReadOnlyDisplayChangedHandler handler)
    Notification method called when the `readOnlyDisplay` setting is modified. Developers may make use of this to toggle between an editable and a read-only appearance of the `canvas`.

    The default behavior is: when the `canvas` is a `DynamicForm`, the form's `DynamicForm.readOnlyDisplay` setting is set to `appearance`.

    Standard `CanvasItem`-based form items may customize the default behavior.

    Parameters:
      `handler` - the readOnlyDisplayChanged handler
    Returns:
      `HandlerRegistration` used to remove this handler
