Self-instantiating link between a 'Business Graphic Object' and its corresponding object in the application.
Library: ilvproto
The IlvProtoMediator class is an IlvGroupMediator that clones a given prototype at creation. This allows you to create graphical user interfaces (GUIs) for application objects created at run time. You can create multiple graphical representations of objects of the same class, each having its own values, but sharing the same behavior.
See the samples in the views directory: samples/protos/interact_synoptic and samples/protos/synoptic for examples of use.

Constructors.
These constructors create a new instance of IlvProtoMediator by instantiating the prototype proto passed as an argument and linking its clone to object, in order to represent the specific values of object in the user interface. The prototype instance implements the presentation in the user interface while object is an object of the application domain. The first constructor expects its proto argument to be of the form prlibrary.prname. It looks for a library named prlibrary in the display path, as explained in IlvPrototype and IlvLoadPrototype, then looks for a prototype named prname in that library. The second constructor instantiates the argument proto instead of searching for a library.
| display | Display used to initialize the presentation. |
| proto | Prototype to be cloned. |
| object | Reference to any kind of object of the application represented by the prototype instance. |
| void IlvProtoMediator::install | ( | IlvContainer * | holder | ) |
See below.
| holder | IlvContainer to install the group into. |
| void IlvProtoMediator::install | ( | IlvManager * | holder | ) |
See below.
| holder | IlvManager to install the group into. |

Place the prototype instance in a scene.
These methods place the prototype instance in a scene. When you add a prototype instance to a scene, you may want to change the x and y values of the prototype instance to place it in a particular place in the scene. Alternatively, you may set the centerX and centerY values, to ensure that the prototype instance is centered correctly.
| holder | Graphic holder to install. |
Sets the presentation that will allow the user to edit the object.
Each IlvProtoMediator instance owns its presentation (the parameter g). Therefore, the presentation is destroyed when the instance is destroyed.
Reimplemented from IlvGroupMediator.
