Re: Improving 10.3 scroll bar auto-hide behaviour?


Basically, all my NSOutlineViews, will display a scroll bar when it's not necessary. 

OK. I've pinned this down even more.

I have one NSOutlineView which isn't even having reloadItem or reloadData called on it. It's filled on startup, and that's it.

And yet this NSOutlineView also has this unncessary scrollbar. Basically what happens, is that it's drawing the vertical scroll bar when the horizontal size drops below a certain height.

So this doesn't really make sense, because the horizontal size should have NO BEARING on the vertical scroller.

Also, it works the opposite of what you'd expect. You'd expect the scroll bar to disappear if there was not enough space to display it without covering text.

But it does the opposite, the scroll bar is not visible when there is enough space to display it without covering text. But it IS visible when it would cover some text.

Is this a MacOS bug? Do I need to override some NSOutlineView methods to make the scrollbar appear as expected?
