I have a tableview that's neatly wrapped in a scroll view by IB.
I manually
resize the scrollview whenever a row is added to the tableview so
that all
the row are always visible. Thus I basically don't need a scroll
view.
However even though it can't actually scroll the tableview it
still eats
scroll events when the mouse is over it. I tried ripping the
tableview out
of the scroll view programatically, but that didn't yield useable
results.
Is there a straight forward way to have a scroll view pass scroll
events on
up the responder chain?
Just subclass NSScrollView, and override -scrollWheel: to call
directly through to NSResponder's implementation and bypass
NSScrollView's implementation.
I was thinking this was easy, but now I'm not so sure.
How do you call through to some arbitrary class in a class's
inheritance chain?
It's definitely the way to do it.
Just send it on to [self nextResponder]. that's all!
Ah! Thanks Corbin. Thats the right (and easy) way to do it.
For the record, this works too (and supports tiger, I'm not sure if
Kyle's code does):
- (void)scrollWheel:(NSEvent *)theEvent {
void (*responderScroll)(id, SEL, id);
responderScroll = (void (*)(id, SEL, id))([NSResponder
instanceMethodForSelector:@selector(scrollWheel:)]);
responderScroll(self, @selector(scrollWheel:), theEvent);
}
Cheers,
