Create sidebar in mac app with sections

Question

Hi folks,

I want to create a sidebar in one of my mac applications. Basically it will look much like the Things sidebar.

Here is the picture that I basically want to recreate - http://i48.tinypic.com/c25ix.png

I can't figure out how to show the "sections" (collect, focus and active projects) and how to have certain items always show up (inbox, today, next, etc...) and finally I would really appreciate if someone would explain how to make the active projects section, with the triangle.

Also I need the active projects section to load from an entity in core data.

I would also really appreciate if you could post an example.

Thanks

Answer 1

Apple's "SourceView" sample should be helpful with this.

Answer 2

The active projects section is probably just a 1 column NSOutlineView with no column header.

Answer 3

PXSourceList is an open source NSOutlineView subclass specifically built for mimicking what you posted. I've used it in a number of projects, and it's very easy and flexible to use. I highly recommend it.
