I've got a custom hiview in a window stored in a NIB. The custom

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.
But I am already doing a HIObjectRegisterSubclass() first then
loading the nib.
static HIObjectClassRef theClass = NULL ;
if (theClass==NULL) {
status = HIObjectRegisterSubclass(myviewclassid,
kHIViewClassID, 0, myviewhandler,
GetEventTypeCount(eventType), eventType, 0, &theClass) ;
require_noerr(status, exitRegisterClass) ;
}
status = CreateWindowFromNib(nibRef, CFSTR("mywindow"), &window) ;
Is there more to it than this? Again, this works in Tiger.
I verified that I'm not mistakenly loading the window early
elsewhere either. If there's sample code out there that does this,
I'm more than happy to study it. Otherwise, I'll just create the
custom view at runtime.
