NSSplitView divider position
Is there a direct way to determine the positions of the dividers in NSSplitView. I'm implementing splitView:additionalEffectiveRectOfDividerAtIndex: and would like to create a rect relative to the current position of the divider. If not, are most people calculating this by adding the widths of all the visible child/container views to the left of the divider index? (I've noticed the the widths of collapsed views in the split view still have the original size). Also, it seems that the NSRect returned from this method is interpreted more like an iOS rect ... that is, Y and the height seem to be top down and not bottom up. Is that because the NSSplitView's internal coordinate system is managed as such since the docs say ... The rectangle should be expressed in the coordinate system defined by *splitView*.

Well, you can do that, although you also need to account for the dividerThickness for any intervening dividers. You could also query the NSMaxY() or NSMaxX() of the preceding visible view. (Actually, be careful of the user interface direction. Vertical split views that use auto layout respect the user interface direction, so the views may be laid out right to left.)

You should not assume either way. You should either a) consult the -isFlipped method on the split view, or b) construct a rect in the coordinate system of one of your own views and then convert to the split view's coordinate system using [theSubview convertRect:theRect toView:theSplitView] or [theSplitView convertRect:theRect fromView:theSubView].
