How to design my application

[dlite922]

This more like a general question. I'll be using Swing to display a JTable loaded with data from a file. User changes a column and the changed rows are saved to an XML file (upon clicking Save)

A colleague is creating the library that reads the import file (raw, hex mpeg sections).

I'll just need to read it, keep track of changed rows, and upon clicking a button, those rows are saved to an XML file.

My Question:

How should I setup my classes?

Do I need a gui JFrame Class or a whole bunch of classes to display the GUI?

If you were to design this what would your classes be?


[MAIN]
[MAIN_WINDOW]
[DATA_TABLE]
[SECTION_READER]

I'm so confused. I can't see the big picture because I don't know the details or the architecture thus I don't know where to start.


Thanks,

Dan

Use the model, view, controller architecture (Wiki it if not familiar) as follows:

Extend your colleague's class and add the ability to write to the file in the child class. (Model)

Then create a GUI class. (View)

Have a class that controls the GUI class and file writer class. (Controller)

This is just a starting point, the architecture may have to be changed when more technical details are revealed in the dev process.
