I do something very similar in my app, except I'm not scrolling
horizontally only vertically... I added in a horizontal offset and
you're right the header did not scroll horizontally... Which is not
surprising... the components of a table view only seem to talk to each
other when you click on a scroller... and that "Machinery" as it says
in the docs is apple's secret... or at least its not in the docs I'm
looking at
according to the docs, reflectScrolledClipView only adjusts the
scrollers and nothing else... Also according to the docs apple does
not want anyone working directly with the clipview unless you're not
using the clip view with a scroll view... which you are
I don't see any other way to do it. there are no methods in scroll view
to scroll the view. I ended up doing what you're doing...
As a suggestion (don't know this will work) you might try setting the
bounds of the NSTableHeaderView (NSView) to scroll the header over
yourself... Thats probably how the table view does it when using the
"machinery".

I have an SNTableView that I need to set to a stored scroll position.
The existing code is :
// Scroll Position
theObj = [inDict objectForKey:kSnapshotScrollPosition];
if (theObj)
{
NSPoint thePoint;
sscanf([theObj UTF8String], "%f %f", &thePoint.x, &thePoint.y);
[[[self enclosingScrollView] contentView] scrollToPoint:thePoint];
[[self enclosingScrollView] reflectScrolledClipView:[[self
enclosingScrollView] contentView]];
}
The main view of the table works fine, but the NSTableHeaderView
doesn't scroll to the right place.
1) Is this the right way to reset the scroll position of an
NSTableView?
2) If it is, how do I get the Header view to sync with the table
scrolled position?
Thanks
