</html>Purpose: Improve the perfect calling method.
If you make an editor that provides some cursor leave events, etc., it is best to use this method to operate, because when others use your editor, you may need to use the event methods provided by the editor to handle some Some events need to be rewritten according to special requirements. Therefore, in this case, it is necessary to provide event methods that allow overriding of the event methods provided by the editor!
