1. A method in a computer system for composing a visual program, the method comprising the steps of:

  • when selecting each of a plurality of components to be included in the visual program, instantiating a run-time object to implement the behavior of each selected component and instantiating an editor object for each selected component; and

    under control of the instantiated editor object for a component,displaying a list of available ports for the instantiated run-time object that implements the behavior of the component, each available port corresponding to an event associated with the component;

    selecting a displayed port; and

    directing the instantiated run-time object that implements the behavior of the component to establish a connection between the selected port and a target object, whereby during execution of the visual program the instantiated run-time object that implements the behavior of the component sends an indication of the event to each target object connected to the port upon occurrence of the event.
