Handling NSApplicationDefined events

The relevant docs make it clear how to send an NSApplicationDefined NSEvent, e.g., to NSApp, but I cannot find anything, esp. no examples, about how to handle events of this type. I was assuming that it could be done in AppDelegate. Perhaps not -- but I'd really like to see a description and one

What about revamping OpenUp.app for Snow Leopard?

Hello, I may sound a little bit old fashioned, but I still much prefer Scott Anguish's (of Stepwise.com fame) OpenUp.app application (http://www.stepwise.com/Software/OpenUp/) instead of the MacOS X built in Archive Utility (the default application used to open zip, tar, etc...). OpenUp.app has b

Re: NSDictionary, allKeys and the NSAutoreleasePool

"ar" is not a member of "d"i. allKeys creates an autoreleased NSArray with the keys values retained in indexes. "ar" is placed in the auto release pool when it is created in the allKeys call. When you call [autorelease release] the items are freed when you since the pool is released and fre

Unfortunately, "setDoubleAction:" is not a method on NSCell or any of its subclasses (except NSPathCell). Really all the BWToolkit is doing is skinning. As far as I can tell from browsing through the code, it's not actually changing functionality of the controls. Dave On Sep 3, 2009, at
