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.
