I can do it easily because I use a decorator class that in turn uses a factory class. To do this, I break down the data stream into something abstract: A "table" has a "table header" and a "table trailer", and between those has 0-N "tablerows" A "tablerow" has a "tablerow header" and a "tablerow trailer", and between those, has 0-n "tablecells" A "tablecell" has a "tablecell header" and a "tablecell trailer", and between those has element data The decorator class invokes methods from the factory interface to get the value of, for instance, a "tablecell header". At runtime I plug in either an HTML factory or an XML factory. The HTML factory returns "<td>", while the XML factory would return "<datatag>". Applying different styles is a matter of attaching parameters to widgets. These parameters are used in the various calls to the factory to provide the different widget elements. And that's all there is to it <smile>. Is it a lot of code? Yeah, it can be. It all depends on what you're trying to do, and whether you have a good destination in mind. My classes are far more involved than that, because the data classes have attributes which may in turn affect the display characteristics. They're also designed from the ground up to support bidirectional communication with a persistence server on the AS/400. It all depends on what you want to do.
