Hi,
I'm trying to specify programmatically the scroll position of a view. I've
tried with all of these possibility:
1) [clipView scrollToPoint:myTopLeftPos];
2) [self scrollPoint:myTopLeftPos];
3) [self scrollRectToVisible:myVisibleRect];
I've seen a lot of glitches with all of those.
A) I need to call [enclosingScrollView reflectScrolledClipView:clipView]; if
I want the NSScrollers to be updated.
B) Once done it 1 time, NSRulers are then unable refresh correctly with an
[self autoscroll:theEvent] from a mouseDragged message. It looks like their
"copy on scroll" are completely out of sync with position of the view. If I
do a manual display to make then they draw correctly:
[[[self enclosingScrollView] horizontalRulerView] display];
[[[self enclosingScrollView] verticalRulerView] display];
That way, it seems to work almost: now I start having blinking ruler
marks... I may find another hack for them, however I feel I'm touching
mines. Is there something obvious I'm missing?
Thanks,
Eric
