What would work, would be disabling the focus distance control when the focus area is set to a value different than "all". I have also been considering adding an extra menu entry for the focus distance control, indicating some "neutral" state, but disabling the other control sounds like a better idea. I couldn't find anything reasonable, as there was already the focus distance "normal" menu entry. Then, after the focus are is set to, for instance, "spot", transition to the focus distance "macro" would be only possible through focus area "all" (where the focus distance is enabled again). I guess it's acceptable. It's only getting a bit harder for applications to present a single list of the focus modes to the user, since they would, for instance, grey out the entries corresponding to disabled control. It shouldn't be a big deal though. -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
