| // contained within an HWND, e.g. a control, a window, etc. Specializations |
| // suitable for specific tasks, e.g. top level window, are derived from this. |

| // As long as views are part of this tree, they will be deleted automatically |
| // when the RootView is destroyed. If you remove a view from the tree, you are |
