property ^bool Outlet = null;

The property 'Outlet' provides an interface for the Model-View-Controller (MVC). In the MVC, the widgets (views, controllers) and the application logic (model) are always kept apart. An automatism behind this model ensures, that widgets are notified automatically as soon as the affected model has changed its state. On the other hand, user interactions on a widget cause the affected model to execute the application logic. Usually, a model is a simple Chora object containing several properties and the implementation of onget/onset method.

By assigning a property reference, Outlet establishes a connection between the widget and the model object, the affected property belongs to. After this, the widget is able to read and modify the referred property in response to the user interactions. It is also able to adapt the widget appearance, if the value of the referred property has been modified by another widget or by the application logic itself.
