Hi, I have what I thought was a pretty simple need but I'm not sure how to go about implementing it. At various points in my interface, the user is asked to make a selection of something rather visual (like choosing a layout for a page or a color option.) These selections are made from a pre-defined set of options. Normally you'd use an...
My desktop app connects to a web application that's hosted on Google App engine. Once it authenticates it gets an authtoken cookie that it passes along for all future requests. That all works. But now I want to add "Sign out". I’ve tried to implement Sign Out like this: - (void)signOut { NSHTTPCookieStorage *cookieStorage = [NSHTTP...

I am making an Cocoa app with custom interfaces. So far I have implemented one version of the app using CALayer doing the rendering, which has been great given the hierarchical structure of CALayers, and its [hitTest:] function for handling mouse events. In this early version, the model of the app are my custom classes. However, as the ...
Short and sweet: How can I tell Interface Builder to center a window on a user's screen? I've seen the positioning tool on the inspector, but eyeballing doesn't always land as squarely as I like. Is this something where I should switch over to Xcode and add something to the init or awakeFromNib methods? ...

I have a text field and a button living in a view inside a menu item. The button submits the string in the text field to a function, and that works fine. However, I've also set the button's key equivalent to "return." The key command isn't being picked up, probably because the menu is not the "key" window. I know how to make a window th...
