Hi there,
I know this has to be something really basic, but I'm hoping someone
can tell me why calling [[self documentView] setFrameOrigin:<some
point>]; inside an NSScrollView's drawRect method doesn't work as
expected? I've also tried updating the view with [[self documentView]
setDisplayIsNeeded:YES];, but didn't have any luck. In addition it
seems to be drawing an obscene number of artifacts so I know I'm
missing something.
If you're curious, I've posted a simple example project at:
http://homepage.mac.com/yojimbo/.cv/yojimbo/Public/
CenteredScrollView.sit-link.sit
While I'm at it, can anyone tell me exactly which view I need to "flip"
so that it uses a top-left coordinate space when being resized? Each
of the views I've tried so far (the NSScrollView subclass, the NSView
subclass, and the NSClipView subclass) either end up drawing nothing or
cause a crash. I know it has to be something I'm doing wrong, but if
anyone can point me in the right direction I'd be grateful.
Any help would be appreciated.
Thanks,
Jim
