Why would I? I just overrode the method that draws the background.

Did you do run into any issues with rubberbanding and responsive/momentum 
scrolling?

I've done it by subclassing NSScroller. (The code's not open-source, though.)
As far as I know, that's the only way to do it. It's fairly easy.

Tick marks on scroll bars

2016-06-13 Thread Jonathan Taylor
Hi all,

Does anyone know a way of implementing "tick marks" on a scroll bar, in the way 
that Xcode does to mark code lines where there is an error/warning? From 
reading header files, I can't see any obvious built-in API to implement this 
feature, but perhaps somebody knows of a custom class that somebody has written 
to implement this functionality? It's something I would like to use, and would 
do if it was comparatively simple to do so, but it's not crucial enough that it 
would be worth my time to write a custom subclass from scratch to do it I 
suspect (I have no experience of customizing controls, even if to an expert it 
might be comparatively simple!).

Thanks for any suggestions...
Jonny
