I see. What I intend to do can be extended be a persistent
web-application, So there is an example of a persistent web-application
that can't be done with fastCGI :).
OTOH, I feel that any persistent web-application can be done with a
NoGUIApplication infrastructure, the advantage for those that _can_ be
done as fastCGI applications is that with same, the normal
"Delphi"-paradigm of event-driven main-thread programming can be used,
making it a lot easier to use for experienced Delphi programmers without
much CGI background.
There is no reason why fcl-web cannot be used for this; it is totally
event driven. The only "event" currently defined is the request from
the client.
Well, the fcl-web applications do not support timers, TCP/IP, serial
interfases and postmessage functionality.
So you cannot use it for anything you want, would be my guess.
That is what I supposed :( .
You can use the same mechanism as is used by the TWebApplication,
though. Build your own TApplication descendent, which does all this. But
I thought that was precisely what you are working on?
That is what I already have :).
But (see my earlier mails) I feel it would be more appropriate to do a
new Widget Type than a new Application Type.
This I really don't understand, and never have since you started
the discussion.
There are no widgets in your application. It's a server application
that sits in the background. So why create a new widget type ?
There is, if I understand you correct, an event loop.
All fine, but an event loop can be programmed in various ways,
without the HUGE overhead of the LCL widgetset.
Michael.
