The base class for presented controls that can provide several UI presentations. A presented control uses separate objects to handle a used data (data model) and UI presentation (presentation layer).

The following properties of presented controls that provide a UI presentation:

• Model represents a data model that contains the data used by a presented control.
• PresentationProxy allows the presented control and data model to exchange information with the Receiver, which is the actual presentation layer.
• Receiver is the presentation layer providing the actual visual presentation of the control UI.

The presented control instantiates these properties automatically at run time. An empty model is created as soon as you create an instance of a presented control, and the presentation proxy is created when your presented control loads.

Reimplement DefineModelClass to determine the class that a presented control uses for its data model. Reimplement DefinePresentationName to determine the name of the default presentation proxy that a presented control uses. To define a custom name for the presentation proxy of specific instances of a presented control, handle the OnPresentationNameChoosingevent instead.

The ControlType property determines whether the presentation layer represents your control using a native control of the platform where your application is running (Platform), or the presentation layer represents your control using the default FireMonkey style system (Styled). On platforms for which FireMonkey does not provide native presentation support, FireMonkey uses the default styled presentation regardless of the value of the ControlType property.
