New XSWT feature

Hello,

A long-awaited (by me) XSWT feature landed in CVS today.  There are
several new convenience create() methods for XSWT that return an
interface rather than a Map.  This is easier to explain than to
describe.  For example, given the XSWT code:

         <label text="Host name:"/>
         <text x:id="HostName" x:style="BORDER"/>
         <label text="Port number:"/>
         <text x:id="HostPort" x:style="BORDER"/>

We can define an interface that describes this layout as follows:

      public interface ISelectServerPane {
          public Text getHostName();   // Define getters corresponding
to
the
          public Text getHostPort();     // x:id attributes we care
about
      }

Now (with CVS changes from today) XSWT lets me write the following Java
code:

         pane = (ISelectServerPane) XSWT.createl(holder,
                 "selectServerPane.xswt", getClass(),
ISelectServerPane.class);

         pane.getHostPort().addVerifyListener(myVerifyListener);
         pane.getHostName().setText("localhost");

Look Ma, no ugly typecasts when I use the "pane" variable any more!
Everything is now typesafe!

Dave Orme
