问题 I'm facing a strange behavior with Cocoa NSView on Mac OS X. I've a custom NSView in a NSView container, this custom NSView tracks mouse movements, clicks, and has a tooltip. When I add a NSView above the described view, I can still see the tooltips even if the view with the tooltip is under, behind and not visible. I'm pretty sure that I misunderstood something in the event handling chain. Any help is really appreciated! 回答1: The core issue is that you are not supposed to have overlapping

问题 My app was converted from a non-document-based app to a document-based one. I did that by creating a subclass of NSDocument , called Document . I also created a Document.xib and set its "File's Owner" to Document . Now in Document.xib , I can see there is a window outlet in its "File's Owner". I don't have a window outlet defined in Document . Where does it come from? I guess it is from the super class NSDocument , but I have no access to that variable in Document . What's up with this weird
