Hey ho, I'm trying to create source list like those in the Finder and iTunes. I downloaded Apple's SourceView demo-program and other available source code, but all those programs use NSTreeControllers in their xib-files. I tried to write my source list without such a controller (this seems somewhat too point-and-clickish), and succeded to some extent. The problem is that now, the label-font of the expandable items (like the "PLACES", "DEVICES" and "SEARCHES" groups in the Finder) is not grey and inset, and the sub-items' label-font is a little larger than in the Finder (e.g. disk names, "Documents"-folder label, etc.). How can I fix those issues? ranguvar P.S.: Sorry if I'm being unclear, please ask if you don't understand something!
