User Interface

  The GuiManager is responsible for the operation of the user interface. Its tasks fall into two categories:

• Reporting events to the user. The GuiManager is the central instance for reporting events to the user, such as the arrival of new session descriptions or the end of the availability of new RemoteSources. The GuiManager hides the details of a particular user interface from the rest of application, and offers user notification methods with standardised interfaces instead.
• Administration of component-specific GUI elements. The GuiManager maintains tables of specific configuration or presentation GUI elements. For example, if a Connection object of a certain type must be configured or if the output of a particular Consumer is to be displayed, the GuiManager is queried for the appropriate GUI element. Therefore, it is necessary that all available GUI elements must be registered with the GuiManager during the start-up phase of the application.
