Chris & Tom,

Are there plans for making the Grid and GridViewer become more extensible?

I looked into extending both of them (and associated support classes) but
found some obstacles. One concern is that the javadoc for the GridViewer
states that it's not intended to be subclassed. I've also found numerous
instances of private (or package-private) variables and methods, a final
class, and a package marked internal. I've also found methods that bundle up
alot of functionality, making it difficult to override some behavior without
having to duplicate alot of code.

Please don't get me wrong; I'm not knocking the code at all. These are very
useful components, are well organized, and are greatly appreciated. I'm just
trying to understand if they are intentionally designed to not be
subclassed. While they do cover alot of functionality, and I do intend on
contributing new features to them, I expect that some features will not be
considered useful/general enough for inclusion. It's an understandable goal
to keep the components from getting too bloated. But I think it would be
very desireable for users to be able to extend and provide their own
features and behaviors whenever possible.

Thanks again,
Chuck
