We don't zoom the main window this way because we can't (yet, and it's pretty much a rewrite we may or my not ever want to do). We *do* zoom notation now. Notation and matrix both have the panner-based zoom from "an entire symphony is one pixel" to "one pixel is four times bigger than your screen." This zoom currently has the axes chained. Then the matrix has this other, legacy zoom slider like the main window. Either way that slider is history, but the slider lets us play with what happens when zooming one axis independently, and this whole selection rectangle drawing problem is at least one significant issue that would have to be resolved to make that workable. I can understand the math and the code to get there, but there could be performance concerns caused by the extra calculations slowing down a mechanism that is already pretty slow, and if we have axis-independent zoom, there's the problem of developing a new (instead of off the shelf) mechanism for chaining the two zoom controls together. > ...so just do what you have to do. I think I'll start with one ThumbWheel and we'll see how it feels from there. I won't remove any code, just comment it out or hide the widget or something for now. -- D.
