I've got a custom hiview in a window stored in a NIB. The custom
hiview is embedded in just the content hiview of the window. I
HIObjectRegisterSubclass(myclassid, kHIViewClassID, ...), then load
the NIB. In Tiger, my construct proc/event handler is called
correctly. In Leopard, the construct proc/event handler is never
called. On Tiger, I'm using Xcode 2.4.1; Xcode 3.0 on Leopard.
The Leopard install is a fresh install (not an upgrade).
I debugged this using a sample app that Jesper provided and it looks
like this will happen if you're loading the nib file that specifies
the custom class ID before you actually register that class. This
used to work, but in Leopard we go down a different path if the class
isn't already registered and wind up creating a generic HIObject
rather than an instance of your class. That's a bug, and I'll fix it,
hopefully for a Leopard software update. However, until then, I think
you can work around this by registering your custom classes before
loading your nib file. Please try that and let me know whether it
works for you.
