Drawing a tree with NSBezierPaths

Hi, all.

I have a tree structure in memory, and I want to draw it on the screen. Each branch gets a line segment, and each junction gets a dot.

I just got bitten by the 'paths connect only if they are drawn consecutively, and only if the next segment starts where the last ended' design.

Before I write some tree walking code to do a depth first search, returning one BP for each walk down the tree, has someone already solved this?

I did google on NSBezierPath, tree, depth-first, as well as reading the docs and looking at the CocoaDev wiki.

Scott
