The most common case is to disallow the user from making any selection changes at all; only the program can change the selection. Just reuse whatever logic you've put into -outlineView:shouldSelectItem:. If you want, factor out the validation logic into its own method. If the conditions aren't met, either pass a different set of row indexes to -selectRowIndexes:byExtendingSelection: or just don't call that method at all. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
