Subject: | Mouse drags and the responder chain |
Date: | Wed, 12 Jan 2005 12:58:42 -0500 |
I traced the behavior to [NSWindow -sendEvent:], which does the following:
case NSLeftMouseDragged: v = [_wv hitTest: [theEvent locationInWindow]]; [v mouseDragged: theEvent]; break;Drags are only sent to the object they are over. Thus, even if the scrollbar explicitly requests and gets firstResponder status from the window, it still won't get the events. I'm not sure how the implementation on OS X differs, but it might be that the drags are sent according to the responder chain instead of or in addition to the hit detection. Any thoughts? I'd like to get GNUstep working more similarly to OS X if we can figure out what it does, unless people think there is something incorrect about it.
thanks
