Is someone using MVVM?

[Javier Tarí 23]

I'm deeply interested on this, and would like if anyone here is using/used homegrown MVVM implementations, and wich was/is your experience. Works fine? Is not woth the effort? Is the best since sliced bread?

 

Please, share your experience

Thank you!

Could you expand that a bit? Do you mean in Delphi we don't need it? If that's what you mean, wich would be in Delphi the pattern that gives us the same as MVVM in other platforms?

I've had good luck using it to write a GUI in Delphi which interacts with another program that was written in Python. I use sockets to communicate between the two processes, which has the added benefit of allowing the GUI to run on a different machine if needed, it could even be on a different platform. I've used this same architecture even when the program(s) are written in the same language. The MVVM structure works well for this -- I generally have the View (the GUI) send messages over the socket to the ViewModel, which then dispatches them to the appropriate Model. I use thread-safe queues and background threads for all the I/O so that the GUI is never blocked.
