By FormCreate, I assume you mean TForm.OnCreate event and FormCreate
(which can actually have any name) being the event handler for OnCreate?
Is so, obviously yes, fpGUI does have the OnCreate event.

I think he worded it wrong. I assume he meant that "component fields"
being the componens dropped on a designer form. Under Delphi and Lazarus
those field variables must be located in the Published section of a
Form. In fpGUI they are by default Private and in fact can be in any
visibility section of a Form.
