Protected Methods
| Name | Description | |
|---|---|---|

| CreateLabel | Create and initialize the GoText label for displaying the comment, which normally supports multiple lines and is editable. (Inherited from Northwoods.Go.GoComment) |
| MoveChildren | Overridden. Moving a balloon should change the size and shape, because the anchor might not be moving along. |
