[Jscheme-user] hack-of-the-day: swing-action

[Ken A. <kan...@bb...>]

There are several concerns you must deal with when developing a Java GUI:
- layout - where components go.
- action - what happens when you click on something.
- model - what happens to the underlying data "model" when an action happens.
- update - what happens to the gui when an action happens. 
- enable - which actions are currently enabled.

I've enclosed a slice of code that i'm using in an application tries to separate these concerns:
- layout is delarative, like XUL http://luxor-xul.sourceforge.net/ it could be in xml.
Layout show relative position of components and associates a named action and enabling state with each component. Any action occurs in its own thread.
- model - the model is a simple prototype object which includes named components of the GUI.
- update - Any update occurs in an invokeLater

One way this differs from the Mode-View-Controller pattern is that i'm using a single update procedure.  So i need to think about that more ...
