-initWithFrame: really doesn't matter here, since the table view is contained within an NSScrollView and will automatically resize itself to fit its content. Peter, AFAIK there's no way to disable user-initiated scrolling in an NSScrollView via API. If this is the same scenario as your previous thread, where you had one data table, a row header table, and a column header table, then you've got a couple of options as far as I can tell, all of them pretty advanced: 1. Subclass NSTableView and override -scrollWheel: and -swipeWithEvent: to do nothing. This is probably the easiest method, but the most likely to result in Whack-A-Mole of finding new ways that scrolling can be performed and plugging those holes. You might also need to subclass NSScrollView's implementation of these methods. 2. Embed the row and column NSTableViews inside NSClipViews _without_ an enclosing NSScrollView. Change the code from our previous discussion to message the header views' clip views directly, rather than going through the -enclosingScrollView method. Essentially this means changing [tableView scrollPoint:] to [clipView setBoundsOrigin:]. 3. Put all three table views inside one NSScrollView. Subclass NSScrollView and override -tile to arrange the three views correctly. Having tried similar things myself, this is a fairly difficult endeavor. It might not even be possible. Is there a particular reason you wish to disable user-initiated scrolling in this view? Perhaps you can just turn off visible scrollers in your other table views to maintain the illusion that this is just one big table view. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
