MVC and Swing

Hi,

Can anyone give me a recipe to handle the following problem:

I try to use Observable in the data model class and Observer in the view
class. But I'm unsure, how I can combine these with Swing model classes.
Is it better to use only Swing or only Observer/Observable? In my view
class (JFrame) I have a JListbox and if I select one entry, the view class
calls a method of the data model and the model class notifies its observer
(and this is also the view class). Is it better to enhance the default
model class of JListbox and to use the Listener functionality? Should I
add a new abstraction layer to my project, which represents the data for
the Swing objects (view - representation - data model)? The same problems
I have, when I use JTextfield or JButton, all of these can have models and
these models are not the data model of my project, but represents a part
of it for a specific view.

Is there a general solution?
Thanks a lot
Andre

Having been traumatised many years ago when using MFC/C++ to develop front-end code, I've religiously avoided GUI work since and stuck to back-end / server-side projects.

I'm now having to do more and more GUI work to support my current projects, so I started looking for tutorial / best-practices materials on the net. I was somewhat surprised to find that...

I'm using Jython and in the python script I do: from javax import swing result = javax.swing.JOptionPane.showInputDialog(wC, cmd,"Prompt from " + client.serverName, JOptionPane.PLAIN_MESSAGE) wC is a JFrame, cmd is a String and client.serverName is a String. It won't show the JOptionPane, why?

I have to honestly say I was flabbergasted by this report. Obviously, I have no problems asserting that Java is #1 in the enterprise (JEE), or in the mobile space (JME), and I do know it's made good strides on the desktop, with popular apps like Azureus, Limewire, and others leading the way. But never in a million years did I imagine this. Swing? I thought SWT actually would beat Swing handily! ...

I have put together this article to give people starting Swing an awareness of issues that need to be considered when creating a Swing application.

This article does not go into full implementation details because those can be found by reading the...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
