Object-oriented programming apparatus, object-oriented programming supporting apparatus, component builder apparatus, object-oriented program storage medium, program storage medium for use in object-oriented programming, component storage medium, and object-between-network display method

An object-oriented programming supporting apparatus, comprising:

• a component file to store components, each component serving as one object in combination with corresponding existing software, and including a method of issuing an event of the corresponding existing software through firing in response to a message issued by another object, and a message for informing other objects that the event has issued through executing the method;
• a handler to input an instruction to issue the event of the corresponding existing software;
• an event log file to store a list of the events of the existing software, to be sequentially issued in accordance with an operation of said handler;
• and
• a component coupler to take out sequentially the events from said event log file, to combine the message of a first component issuing the message for informing the other objects that the event is issued and the method of a second component for issuing the event.
