Designing a new core application

I hope this is the right forrum :o
I'm starting a new project for my honors degree, its a component based system whereby the system presents an api to the world and one can program according to that api.
This is a component system as everything except the system itself will be components which will be added and removed in runtime.. now for the questions:
Daemon will be QT4.

- The system is opensource, so I suppose QCoreApllication will be good enough to run the system as a daemon on both linux and windows(opensource eddition)?
- Any ideas what I can maybe search for when it comes to components.. how to design these things and an api?

Anyone knows about any good tutorials or docs on component systems/modules or something that is added to a system in runtime which lets the system communicate with something outside the system through the added component/module?

Any feedback appreciated :o

You didn't write what your system will do, so I can tell you only that you should design them well ;) If you want to create a real Unix daemon, you need a bit more than QCoreApplication.

Hmm... Read Qt docs. And I don't mean "go find your answer in Qt docs", but read the docs to have a look at good API (You might also want to take a look at this). As a side effect you'll find the "plug and paint" example in the docs too, which answers your question about pluggable modules.


BTW. I see Jacek was faster again :P

The Trolls have some of the best api docs I've ever used. See http://doc.trolltech.com/qq/qq13-apis.html for some great advice.

Thanx guys!

It will not be a true deamon as such, it will simple be a program that is started at bootup.

thanx for all the real help real fast :D

Even if you don't have access to Qt Solutions, have at least a look at the documentation of QtService.
