NSStatusBar

Hello, I am developing a finder Menubar app, and am having one mysterious crash. I build the standard menu options when the app launches. Then in a NSOperationQueue I make a network connection and get some data to build out the dynamic data in the menu. If the user clicks on the menubar and disp

Trying to subclass UISwitch

Odd NSCache Eviction Behaviour

Hi all, I've been using an NSCache to store items that should be cached for performance reasons, since they are rather expensive to recreate. Understanding NSCache behaviour is giving me some headaches though. I initialize my NSCache as follows: _cellCache = [[NSCache alloc] init];

Programming Context Menu

Dear all, I am now learning programming on Cocoa following the book, Cocoa Programming Developers Handbook. When programming Context Menus (Page 237), I got a problem. Although the context menu can be shown, it is weird that all of the items in the context menu are disabled. However, when running

I think there is a difference between "customizable" and "not subclassable". The question I guess would be: did he try to subclass? -Laurent. -- Laurent Daudelin AIM/iChat/Skype:LaurentDaudelin http://www.nemesys-soft.com/ Logiciels Nemesys Software

The first thing I tried to do was to subclass the UISwitch. But when one looks at the docs for the UISwitch there are no Properties or Instance Methods that one can override to change the "text" on the switch. And when one looks at the origins of the UISwitch, there is nothing to be overridden t

Dear Volker, I noticed that no IBAction/IBOutlet is available for the items in the code. Should I make some connections for them? I just connect the context menu with the class of ContextMenuView and connect the NSView in the Window with ContextMenuView. Thanks, LB On Tue, Apr 5, 2011 at 4:06
