I must correct my statement, of course: So far nobody succeeded doing so.

Application developers routinely describe GUI like this:

<table>
 <tr>
   <td>
     User:
   </td>
   <td>
     <input type="text" name="usr" value="<%=usr%>">    </td>
 </tr>
 <tr>
   <td>
     Password:
   </td>
   <td>
     <input type="password" name="pwd" value="<%=pwd%>">    </td>
 </tr>
</table>

which is just 4 GUI elements in 4 cells layout table, and this approach proved to be quite sucessfull. For comparison, try describung this trivial GUI page in relational to see what I mean. Received on Sun Oct 26 2003 - 20:33:34 CST
