I guess if someone wanted different size shadows for different z-order, a fixed distance between levels could be simulated with all windows shuffling down when a window is brought to the top. cheers -ben

Normally, the order of HTML determines the Z-order. But, Z-order is really a style thing, rather than a composition thing. So, specifying the Z-depth allows you to override standard behavior in the style sheet. This is not necessary in a true object-based GUI where graphical objects are more self contained and can easily determine their own Z-order. I doubt we will see general purpose adoption of any 2D interface that will rely on Z-depth for anything besides determining Z-order. For instance, the example of shadow size seems interesting but runs into usability problems quickly. Let's say that you have element A with a larger shadow to indicate that it is above element B with a smaller shadow. That seems great. What happens if element B is selected and brought to the forefront? Does A's shadow go down in size? If so, that breaks the normal shadow analogy. If not, it would seem that the shadows would just keep growing bigger each time a new element is brought to the front. For limited general-purpose applications (e.g., a larger shadow for an object currently being dragged), you don't need Z-depth info. For specialized applications where a Z-depth might make sense (I can't even think of one), there's little problem adding such functionality to custom widgets. So, my recommendations is to stay away from trying to implement Z-depth as a fundamental component of a 2D interface. The benefit is minimal and largely theoretical. Cheers, Jeff
