mouseDragged and bindings

Problem: a declared property in a NSView subclass doesn't update members bound to it (with bindings) when in a mouseDragged method. So I have a subclass of NSView that has an ivar that I declare as a property.   In IB I have a NSTextField that I set the binding to the same variable (and I do eve

Blocks with return type

I have a typedef (no complains from Xcode - so I assume it to be correct): typedef unsigned long (^LongBlock_t)(id a); Now I want to set a variable to some block: LongBlock_t aBlock = <...some magic here...> { (void)a; unsigned long x = 5; return x;}; What should <...some magic here...> lo

Re: Constraints Question

You probably want to set the content hugging priority of the button to a lower value (probably UILayoutPriorityDefaultLow). By default, buttons have an intrinsic constraint that says they don't like to grow vertically (it likes to "hug" its content strongly in the vertical direction). [myButto

Constraints Question

I am trying to wrap my head around the auto-layout functionality. I have a sample project at: http://ericgorr.net/cocoadev/constraints.zip After opening the project, take a look at ELGFirstViewController.xib. This app will only be used in landscape. On this XIB, there are three object

Crash when loading NSViewController view with NSArrayController

Hi, I need help. I'm still stuck with a crash a posted here a couple of weeks back and there is some more information now but I'm still at a loss understanding what is going on. The crash happens when calling [viewController loadView] during the nib decoding process of an NSArrayController

Re: NSPredicate / NSArray addObserver:forKeyPath:options:context: exception

Is "Auto Rearrange Content" of the array controller switched on? The array controller can't observe to-many relationships. Does NSPredicateEditor work with to-many relationships? I don't think so, but I'm not sure. ___ Cocoa-dev mailing list (Cocoa-de
