Hi List,I have an app with a bound NSOutlineView (source list style) and I'm wondering if there's a way to prevent deselection of a selection by the user. The delegate method
- (BOOL)outlineView:(NSOutlineView *)outlineView shouldSelectItem: (id)item;
is not called when no new item is selected (for example if the user clicks in the empty space of the outline view, or when COMMAND-clicks the selected item).
Basically I'd like the outline view only to change selection to other items, but not completely deselect all items. Is there a way to do this?
The closest thing I came up with is re-setting the selection indexes of the tree controller to the last known selected item (via - performSelector:withObject:afterDelay:0.0). However, that produces a flicker effect because the selection goes away briefly before it comes back. Resetting the selection index from within a change notification (via observing -selectedObjects of the tree controller) has no effect.
