How do enforce a scrollPageDown on a view?

Subject: How do enforce a scrollPageDown on a view?
From: Steve Palmer <email@hidden>

If I send a scrollPageDown: to an NSTextView or a WebView, the scroll view isn't actually scrolled by the time I've sent the message. Instead the view seems to queue up the scroll for a later pass through the run loop or in response to a delayed notification - not sure which. What I want is to enforce the scroll when I send the message so that I can do something with the view knowing that it has at least tried to scroll. (Whether or not it actually scrolls is immaterial as I can check for that by comparing the visibleRect before and after.)

My hack has been to start a 0.2 second timer to fire after I've sent the scrollPageDown. I want a better solution that allows me to send a message to the view immediately.

Any ideas?

Thanks!
- Steve
