Sometimes these implicit interfaces are just too obtuse. I wasted a DAY figuring this out.
\nI needed to mark my class (SakaiDesktop) as a delegate for a NSOutlineView control on my window. I knew that it had something to do with dragging. The last step is what is missing.
\nPlace Mouse over the Outline Control on the Window
\nControl-Drag from the Window to the instance of SakaiDesktop and release
\nThe Inspector will switch to Outlets (this is what kept confusing me)
\nSwitch *back* to Actions in the Inspector – delegate and datasource will be there – click on the row for delegate and the instance willbe the designated delegate.
\nFunny how this did not work:
\n[myOutline setDelegate:self];
\nWhen I did it in init.
\nThe problem I had was without being set to the delegate, the
\n– (void)outlineViewSelectionDidChange:(NSNotification *)notification
\nNotifications were not being delivered.
\nIf the people who built NIB builder just made it so that picking a delegate used a drop down list instead of this multi-click gymnastics, I would be much happier.<\/p>\n","protected":false},"excerpt":{"rendered":"
