(For the time being the focus will be on lists, not heirarchical trees.
The tricky part of a list controller/view is that you have a controller/view on a sequence. You need to figure out:
- How to communicate requests for changes to the sequence
- What those requests are
- How to communicate a change in the visible portion of the sequence to the view
We assume the sequences in a list are disjoint.

Request Types
| Request Type | Description | Single Node? | Multi Node? | Parent Target? |
|---|---|---|---|---|
| Insert | Create a new node in the tree | Y | Y | Y |
| Delete | Remove a node from the tree | Y | Y | N |
| Move | Change the parent of a node in the tree | Y | Y | Y |
| Visible Update | Notify the user of the sequence of nodes that are currently visible in the view | Y | Y | N |
Typedefs
Assume for the time being that the model_type is simple:
typedef std::vector<std::string> model_type; typedef model_type::iterator iterator; typedef std::pair<iterator, iterator> sequence_type;
Model API
void insert(const model_type& what, iterator where);
