IMHO, the optimum design is to adhere to the "separation of business
logic and GUI" paradigm (that in fact is not even created with embedded
applications in mind) and do the program in a way that it has a switch
to compile it with and without the GUI. So at best the version without
the GUI should use an infrastructure ("Interfaced" / "Wideget Set" /
"Platform") that does not force a GUI binding.
However with Linux it's possible to boot a system with the dummy X
driver, and it's also possible to run GUI apps in a VNC session which
in my experience is reliable.
This is exactly what I have been planing regarding the bad luck
regarding any kind of active NoGUI Widget Set.
I wonder whether I could ask a silly question: is there any feasible
way that an app using the LCL can "re-skin" itself, i.e. switch to a
different widget set such as nogui, without restarting?
I don't think so, and I don't see the point. For me the question is
whether an application can start without an interface to a GUI
infrastructure (such as "X") is found in the system.
