I'm trying to show a tooltip on the mouse hover at a NSImageCell. I've tried setting the property on Interface Builder (both on the NSImageCell and the NSTableColumn that contains it) but it didn't work.
Any ideas?
I solved this by overriding this method in the controller for my NSOutlineView:
- (NSString *)outlineView:(NSOutlineView *)outlineView toolTipForCell:(NSCell *)cell rect:(NSRectPointer)rect tableColumn:(NSTableColumn *)tableColumn item:(id)item mouseLocation:(NSPoint)mouseLocation;
