Gumby vs SwiXML/SwixNG - Comments?

Hello,

  Yanick Duchesne writes in response to the question
"Can you let us know how Gumby differs from
established Swing XML UI language (XUL) frameworks
such as SwiXML or SwixNG?":

1) Gumby makes use of XML namespaces, which allows
cleany separating tags pertaining to Swing vs Gumby
tags vs your own tags: name collision risks are
minimized.

2) Gumby IS Swing - it does not abstract Swing
details:

SwixXML:

<button Text="Click Here" Action="submit"/>

Gumby:

<swing:JButton text="Click here">
  <actionListener>
    <myTags:submit />
  </actionListener>
</swing:JButton>

3) Gumby has built-in support for scripting

In the preceding example, SwiXML tag delegates action
handling to a method called "submit" - invoked through
Java reflection. This implies that your must code your
actions in Java (or at least part of them, since this
is what SwiXML expects).

With Gumby's built-in support for scripting, action
handling code can be scripted, sparing you the tedious
code-compile-test cycles. Thus:

<swing:JButton text="Click here">
  <actionListener>
    <gumby:Expr>
    import java.awt.event.ActionListener;
    import java.awt.event.ActionEvent;
    new ActionListener(){
      public void actionPerformed(ActionEvent e){
        ....
      }
    }
    </gumby:Expr>
  </actionListener>
</swing>

4) Databinding

Gumby support databinding and MVC in a very clean way.
You can use Gumby's built-in JXPath-based tags to
handle basic form input, or you can implement your own
bindings.

5) Ease of extension

Having a look at the source of Gumby tag
implementations will prove to you how easy it could be
to implement your own tags. Everything is
reflection-based.
