Hi all again.

I would like to know wich is the right way to follo MVC pattern and OOP on Lazarus/FreePascal.

Thanks in advance.

I have a partial implementation of MVP that is FPC compatible, it is very close to MVC.
Im now finishing a big refactory, not commited yet.

The easiest way for you to achieve your tasks imho :) MVC is not a religion but an approach. Personally I use it for many years and only recently learned the term. your data and logic need to be at two different locations, and the visual display have also a different location, however, if it makes things harder, then you can mix things up to make your work better and easier...

Thanks in advance.

MVC MVP and more

I would like to know which is the right way to follow MVC pattern and OOP on Lazarus/Free Pascal.

That's a very open ended question... MVC, MVP, MGM etc are all design patterns. They help to keep you business classes and GUI code separate.

I don't use MVC, but rather Model-GUI-Mediator (MGM). For me, it's more geared towards todays more intelligent GUI toolkits - taking advantage of it's built-in event handling. It's also very easy to implement. I have implemented MGM using Lazarus's LCL with tiOPF. I have also ported that implementation to fpGUI with tiOPF. Source code and examples are available for both in the following SubVersion repositories....

tiOPF v2: http://www.tiopf.com
fpGUI: http://opensoft.homeip.net/fpgui/

For more information about Model-GUI-Mediator have a look at: http://www.atug.com/andypatterns/mgm.htm

Thanks to all for the links.

Cheers.

I think it would be good if you update your site somewhat.

From what I see, I would conclude that the project is dead...
