34 // TODO: Need to be able to support child windows.
35 // Thus, I need a tree and this class should be a node of the tree.
36 // I could use an STL multimap container that maps child nodes onto parent nodes
37 // The root node would need to be a bit special. Perhaps it would map to itself.
38 // Use the equal_range() method to get the children of the specified node.
39 // I would still need to implement my own tree walking methods: get root node,
40 // for each child (get children and recurse).
41 //
42 // It may be more efficient to implement the tree directly instead of using
43 // std::map as an intermediary.
