So I have noticed that there is a lot of animosity towards Objective-C among programmers. What's your take? Is it a vendor lock-in thing against Apple? General antipathy towards Apple? The syntax? What's your view on this? With the advent of the iPhone SDK, Obj-C has gotten a lot more attention lately, and I am curious what people on SO...

Hi, I'm inserting a hook in the MFC message loop so that the Qt events are treated, without running ->exec() on qApp (because it's blocking): LRESULT CALLBACK myHookFn(int ncode, WPARAM wparam, LPARAM lparam) { if (qApp) qApp->sendPostedEvents(); return CallNextHookEx(0, ncode, wparam, lparam); } and int argc = 0; new QAppli...
The documentation for -hash says it must not change while a mutable object is stored in a collection, and similarly the documentation for -isEqual: says the -hash value must be the same for equal objects. Given this, does anybody have any suggestions for the best way to implement -hash such that it meets both these conditions and yet is...

In my question "How do I get -[NSString sizeWithFont:forWidth:lineBreakMode:] to work?", I learned that -[NSString sizeWithFont:constrainedToSize:lineBreakMode:] was actually what I needed.
