ViewModel View 

The Model View provides the logical representation of the model of your project: namespaces (packages) and diagram nodes. Using this view, you can add new elements to the model; cut, copy, paste and delete elements, and more. Context menu commands of the Model View are specific to each node. Explore these commands as you encounter them. 

In the Model View, only the nodes and their respective subnodes shown in the Diagram View are listed under the corresponding diagram node. For example, if you have a namespace (package) containing a class, both the namespace (package) and class are shown under the diagram node in the Model View. However, any members of the class are not shown under the diagram node as they are displayed under the namespace (package) node only. 

Although the Model View opens initially as a free-floating window, it is a dockable window. The docking areas are any of the four borders of the RAD Studio window. You can position the Model View window according to your preferences. 

The following options are applicable to the Model View:

• In the Show diagram nodes expandable field (OptionsTogetherModel View) choose True to show, or False to hide expandable diagram nodes. By default, the Model View displays expandable diagram nodes with the elements contained therein. You can hide expandable diagram nodes to further simplify the visual presentation of the project.
• In the Show links field (OptionsTogetherModel View) choose True to show, or False to hide expandable diagram nodes. By default, the Model View does not display links between nodes. You can opt to show the links to make the visual presentation of the project more detailed.
• In the Sorting type field ( OptionsTogetherModel View) choose Metaclass, Alphabetical, or None to sort elements in the Model View. By default, diagram nodes are sorted by metaclass. You can sort elements in the Model View by metaclass, alphabetically, or none.
• In the View type field (OptionsTogetherModel View) choose Diagram-centric or Model-centic from the list box. For the sake of better presentation you can opt to show your model in diagram-centric or in model-centric modes. The Diagram-centic mode assumes that the design elements are shown under their respective diagrams; the namespaces only contain classes and interfaces (and the source-code elements for implementation projects). The Model-centric mode assumes that all elements are shown under the namespaces.
