True is that nowadays NON-GUY envs. tend to disappear; but you need to

Embedded stuff, CGI, Daemons/Services you name it.
Since years, I always advocated that it should be possible to do non-GUI
software in a decent way. But here, Lazarus is severely lacking support:
there is _no_ Widget type that allows for normal "Delphi-Type" event
driven programming style, without requiring a GUI binding. (Because no
"Main Loop" and no event queue for timer- or thread generated events is
implemented.)
The event handling, which you want to use, must be implemented and also
must be supported by the platform and process type - else you cannot get
events at all. AFAIR there exists a noGUI widgetset, which implements
the message processing (for Timer...) in a non-GUI application.
Otherwise you have to ask the FPC people for message support apart from
a GUI.
