In the document view structure, the default command processing
In the framework built in the document view structure, many command IDs have default command processing. Many features are completed by them, but these features are not "visible" in the program, not convenient to understand the program.
The following summary of common default processing and its processes
You can reload these functions to achieve specific features when needed
