Guidelines

• Derive your embedding subclass from TGUIModel.
• Override the inherited Adopt and Orphan methods to provide subclass-specific behavior. These methods are generally used to add or remove components from the embedding hierarchy.

You can make use of the AddComponent and RemoveComponent methods of the superclass.

• Based on the type of data to be stored (native or foreign), provide functions to determine the type of model to be used.
• Provide functions to absorb the data in the model or to embed the model if the data cannot be absorbed.
• Derive a selection subclass from the TGUIModelSelectionFor<> template class.

If you want a specific selection behavior for your embedded models, you will need to override the methods in the MEmbeddedComponentAccessor superclass.
