    - #### addCanEditChangedHandler

          com.google.gwt.event.shared.HandlerRegistration addCanEditChangedHandler(CanEditChangedHandler handler)

      Notification method called when the `canEdit` 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:

      - If `canvas` is a `DynamicForm`, the form's `DynamicForm.canEdit` setting is set to `canEdit`.
      - `shouldDisableCanvas()` is called to determine if the `canvas` should be disabled.

      Standard `CanvasItem`-based form items may customize the default behavior. For example, a `MultiComboBoxItem` will hide its `comboForm` if the `readOnlyDisplay` is `ReadOnlyDisplayAppearance.READONLY` or `ReadOnlyDisplayAppearance.STATIC` and also disable the buttons when made read-only.

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