A little while ago I posted a query here asking if anybody knew of a Cocoa
class to create a weekly calendar, somewhat like the iCal week view. Although
there were a couple of promising replies, I decided to roll my own,
"CSWeekView". I've released it on GitHub under the LGPL.

Does anybody know of some Cocoa classes that would allow me to mimic the week
view shown by iCal? I've looked around for such a thing online without success.
Also, in case there are none out there in the wild: I'm looking for some
pointers on how to implement this weekly calendar view. Here ar
Ah, I see. Strange that this would be the default behavior.

Okay, all: can somebody explain this error to me? The debugger isn't
much help and the problem is not in my code (because I can reproduce
this without writing any code!).
1) Make a new document-based cocoa project in XCode.
2) Open MainMenu.xib in IB, add a new blank window. Set the window

This is quite helpful, Quincey, but one thing you wrote surprises me:

implementation will not generate any KVO notifications. Changing the
