Take the 2-minute tour ×  I notice that Mail.app, iTunes and
even Finder have a similar template, with a various columns, but
often, a left Column with "folders" and "files". Is this a sort
of standard template, that I can use so as to not reinvent the
wheel?   share|improve this question add comment  2 Answers  up

that acts like a finder window, etc., although it is a common
request and you might want to file a bug report at
http://bugreport.apple.com making this request...it would help
push them along to provide such a standard control.  However,
there are several controls that implement various aspects that
you may want to take a look at like NSTableView, NSOutlineView,
NSCollectionView & IKImageBrowser.  Although, to get everything
you want, you may have to reinvent the wheel. I have generally
found these control hard to customize if they do not provide
everything you need out-of-the-box...but they do provide a lot
out-of-the-box.  share|impr
