    The GUI Painter provides the user with a graphical user interface for building own 

    interfaces by interactively assembling widgets and defining the behavior of the widgets.

    The resulting interface specifications can be saved as methods on the application

    classes, typically subclasses of the class ApplicationModel. These specifications

    are used by the UIBuilder to generate the application window and its widgets when 

    opening the application.

                                as opposed to a regular painter, which stores the spec in a class.

                                A spec-only painter has no class to store additional specs (esp.

                                menu- and tabSpecs) and should not offer postBuild and other

                                callback functions.
