As jipété appears to be a Linux user, a far simpler approach is possible, put writeln('<Event Name>') in each event handler, that way, they appear even before the form is shown and in the actual order. See the printout in View->DebugWindows->ConsoleIn/Out.
You can do the same in Windows using debugln() but need to capture that output to a file (or tell the app it does really have a console...).
