Presenter states

A presentation is a media-specific representation of the content information found in a model. It is not simply how data would be displayed. It is, more correctly, how data will be rendered for and edited by the end user in a given media.

The presenter state data holds information that allows it to inform the presenter how the data held within the model should be viewed. The presenter state is persistent data--analogous to that data stored in the model, but it is specific to the presentation used.

Each component of a document has a presenter state object class defined for it. This class has member functions that allow it to create a content view for the presentation of the presenter state and its associated model.

Redrawing Figure 62 with an awareness of the relative importance of the model and the presenter state, it would look like this:
