User operation log recording and storing apparatus using object-oriented technology

A program for implementing a user operation log saving function using object oriented technology, said program, when executed on a computer, causing the computer to provide:

• a plurality of objects each having a model part, a view part and one or more slots, for processing information in response to said user operation directly applied to said first object via a user interface;
• and
• a second object having a model part, a view part and one or more slots, for operating as a desktop environment in which said first objects operate,
• wherein
• said slots exchange data among said plurality of first objects and said second object,
• said model part has a data storage part for holding data to be exchanged, and
• said data storage part of said first object stores, as a log file, the following:
• an attribute and corresponding attribute value of said first object,
• results of user operations and
• contents of said model part including attribute values of a slot through which said first object exchanges data with another object when said first object is linked with said another object.

• said model part having a data storage part for holding data to be exchanged, and
• said data storage part of said first object stores, as a log file, the following:
• an attribute and corresponding attribute value of said first object,
• results of user operations actions, and
• contents of said model part including attribute values of a slot through which said first object exchanges data with another object when said first object is linked with said another object.
